SUMMARY:[ESS] Kip Hodges (Arizona State U.)
DESCRIPTION:“Refining the Impact History of the Moon: The Value of Multisystem Geochronology and Thermochronology”\nMost exposed rocks on the Moon are highly brecciated as a consequence billions of years of meteorite impacts. As is the case with breccias of all origins on Earth\, these “impactites” are extremely difficult to date accurately and precisely. In this seminar\, we will explore the nature of these complexities and learn why the application of multiple geochronometers to individual impactite samples is helping to disentangle such complexities and improve our understanding of the impact history of the Moon\, a high priority for lunar science over the coming decade. \n\nEarth Science Seminar — \n\nLecture portion of the EAPS graduate-level class 12.571\, covering current research in geophysics\, geology\, geochemistry\, and geobiology. All members of the MIT community are welcome to join for presentations by guest speakers\, held approximately every two weeks during the term. \n\nContact: earth-science-seminar-info@mit.edu earth-science-seminar-info@mit.edu \n\nAttend Virtually: \nhttps://mit.zoom.us/j/94298370383 \n\nEAPS Calendar Detail Page: \nhttps://eaps.mit.edu/events/ess-kip-hodges-arizona-state-u/

SUMMARY:[DLS] Kip Hodges (ASU)
DESCRIPTION:“Co-Evolution of Tibetan Plateau and the Himalayan Orogenic Wedge”\nMany large\, hot orogenic systems feature both orogenic wedges and adjacent\, high-elevation\, low-relief orogenic plateaus. This duality has important geodynamic consequences because lateral expansion of plateau crust under the influence of gravity may strongly affect wedge evolution. In the Himalayan-Tibetan orogenic system\, the southern Tibetan Plateau margin is a long-lived – not transient – feature\, represented by deformation zones with complex kinematic histories that record plateau-wedge interactions through time. The modern boundary that separates the Tibetan Plateau and the central Himalayan orogenic wedge appears not to have migrated significantly since middle Miocene time a significant fraction of the entire evolutionary history of the orogenic wedge. It is marked by multiple generations of oblique-slip faults striking subparallel to the Himalayan arc. In the past\, these structures accommodated both normal and dextral strike-slip displacement\, reconciling contemporaneous arc-parallel displacement of the extending Tibetan crust and arc-normal shortening within the Himalaya. Several lines of geomorphic\, structural\, and geochronologic evidence combine to indicate ongoing structural activity along this boundary in the central Himalaya west of 88° East longitude. However\, surface evidence for similar deformation at the plateau-wedge boundary is lacking farther east along strike. This change coincides spatially with a zone of predominantly dextral transcurrent faulting separating the orogenic wedge into distinctive central and eastern domains. Seismicity in this zone reflects active strike-slip deformation in the sub-wedge Indian basement\, in contrast to the thrust-related seismicity characteristic of the basal decollement of the central Himalayan wedge. My colleagues and I suggest that this change in the nature of the orogenic wedge as well as the plateau-wedge transition zone is not only related to changes in the subjacent Indian lithosphere but also to focused\, south-southeastward flow of Tibetan Plateau crust. In our model\, this flow may have played an important role in broadening of the Himalayan orogenic wedge to include the enigmatic Shillong Plateau region of NE India and a substantial (up to ca. 6 mm/yr) increase in the rate of net shortening across the wedge. \n\nEAPS Department Lecture Series — \n\nWeekly talks aimed to bring together the entire EAPS community\, given by leading thinkers in the areas of geology\, geophysics\, geobiology\, geochemistry\, atmospheric science\, oceanography\, climatology\, and planetary science.

SUMMARY:[FISH] Andrew Seltzman (MIT PSFC)
DESCRIPTION:Brimstone: A New Computational Model Integrating Microwave Physics with Drilling Economics for Ultra-Deep Geothermal Access\n\nSuperhot-rock geothermal energy could provide clean power generation over broad geographic areas if economical access to deep crystalline rock becomes feasible. Conventional drilling becomes prohibitively expensive beyond 5 km depth\, while millimeter-wave (MMW) drilling offers an alternative by using high-power electromagnetic radiation to ablate rock without mechanical contact. We present Brimstone\, a simulation package that couples microwave physics to drilling economics – providing the first comprehensive model for evaluating economic viability of MMW drilling for superhot-rock geothermal access at 10–15 km depths. This simulation integrates first-principal RF transmission physics\, borehole pressure management\, drilling operations\, and project economics. RF losses from ohmic dissipation are small compared to loss contributions from waveguide junction angular misalignment and pressure-driven absorption on the nitrogen-filled waveguide.\n\nBy coupling RF simulations with drilling simulations tracking pressure constraints and casing requirements\, an economic analysis reveals that rig time dominates borehole cost\, largely due to time for waveguide segment insertion and casing operations to maintain borehole pressure between blowout and fracturing limits as a nitrogen borehole fill provides lower hydrostatic pressure than conventional drilling mud. Frequent casing operations are necessary\, demanding time-consuming waveguide withdrawal and reinsertion. For 15 km boreholes in crystalline rock\, predicted costs range from $160–250 million and LCOE of $250–395/MWh-e for a 250 MWe plant when utilizing currently available casing operations used in mechanical drilling applications. MMW drilling may enable in-situ generation of a vitrified glass borehole casing\, increasing the incremental depth between casing operations and reducing borehole cost. Development of vitrified glass casings\, improved waveguide insertion times\, and transmission line engineering may reduce the LCOE of superhot-rock geothermal to be competitive with near surface plants.\nFriday Informal Seminar Hour — \n\nPostdoc-run seminar series within the Earth Resources Laboratory http://erlweb.mit.edu (ERL). Features talks by ERL members as well as special guests from academia and industry on earth science and energy transition topics including geothermal energy\, carbon sequestration\, geologic hydrogen\, and critical minerals / in situ mining. \n\nContact:  fish_seminar_organizers@mit.edu \n\nAttend Virtually: \nhttps://mit.zoom.us/j/95374035027 \n\nEAPS Calendar Detail Page: \nhttps://eaps.mit.edu/events/fish-andrew-seltzman-mit-psfc/

SUMMARY:[PAOCQ] Hanqin Tian (BC)
DESCRIPTION:“Toward a Predictive Understanding of Coupled Carbon–Nitrogen Cycles in the Earth System: A Scientific Journey”\nThe Earth system is shaped by largely invisible biogeochemical fluxes and pathways connecting land\, water\, and atmosphere. This presentation traces a scientific journey toward making these processes measurable\, attributable\, and predictable. Four turning points are highlighted: from single to multiple interacting environmental and human drivers; from carbon to integrated COâ‚‚\, CHâ‚„\, and Nâ‚‚O budgets; from an overlooked Nâ‚‚O cycle to comprehensive global assessment; and from terrestrial ecosystems to inland waters and the land–ocean continuum. Together\, these advances demonstrate how connecting biogeochemical cycles\, greenhouse gases\, ecosystems\, and human activities can deepen predictive understanding of the Earth system and inform climate mitigation and sustainability. \n\nHanqin Tian is an Institute Professor at Boston College\, where he directs the Center for Earth System Science and Global Sustainability and the Boston Office of the Global Carbon Project (GCP). His research focuses on Earth system biogeochemistry\, terrestrial biosphere modeling\, and interactions among climate change\, carbon\, nitrogen\, water\, and human activities. Dr. Tian is a Clarivate Highly Cited Researcher with more than 500 scientific publications and an h-index of 130+. He received the 2025 AGU Bert Bolin Global Environmental Change Award and the 2026 Humboldt Research Award (Humboldt Prize). He is an Andrew Carnegie Fellow (Brainy Award) and Fellow of American Geophysical Union (AGU)\, the Ecological Society of America (ESA)\, and the American Association for the Advancement of Science (AAAS). \n\nPAOC Colloquium — \n\nInterdisciplinary seminar series that brings together the whole PAOC (Program in Atmospheres\, Oceans\, and Climate) community. Seminar topics include all research concerning the physics\, chemistry\, and biology of the atmospheres\, oceans and climate\, as well as talks about societal impacts of climatic processes. \n\nContact: paoc-colloquium-comm@mit.edu paoc-colloquium-comm@mit.edu \n\nAttend Virtually: \nhttps://mit.zoom.us/j/99778456236 \n\nEAPS Calendar Detail Page: \nhttps://eaps.mit.edu/events/paocq-hanqin-tian-bc/

SUMMARY:[ESS] Lubna Shawar (California Institute of Technology)
DESCRIPTION:“Intramolecular Isotope Structure of Biomarkers: A Frontier Tool for Source Attribution”\nBiomarkers\, molecular fossils derived from once-living organisms\, preserve biosynthetic signatures that reflect biological sources\, environmental conditions\, and depositional settings. Their structural fidelity makes them powerful tools in geochemical reconstructions\, petroleum exploration\, and environmental forensics. However\, structurally similar or identical compounds can originate from taxonomically diverse organisms\, and post-depositional (diagenetic) processes may further alter biomarker structures\, complicating source attribution. \n\nIn this talk\, I will present two complementary research efforts aimed at addressing these challenges. The first draws on classical organic geochemistry: identifying novel biomarkers\nthrough structural analysis\, source comparison\, and model compound synthesis. Specifically\, I will share results from my postdoctoral work at MIT\, where I identified two previously unrecognized C31 steranes (namely: 24-n-butylcholestane and 24-sec-butylcholestane) in Neoproterozoic sedimentary rocks. Their structures were confirmed through synthesis of model compounds\, coinjection with geological extracts\, and analysis using GC-QQQ-MS. These steranes were traced to C31 sterol precursors found in modern demosponges\, reinforcing the value of C31 steranes as molecular fossils of early animal life. \n\nThe second part of my talk introduces a new analytical frontier for biomarker-based source attribution\, developed during my research at Caltech. This work presents the first successful application of site-specific isotope analysis (SSIA) to steroidal compounds\, providing a foundation for extending this approach to steranes preserved in the geological record. SSIA uses isotopically resolved molecular fragments to recover position-specific isotope information within a molecule\, revealing source and transformation signals that are obscured in conventional bulk and compoundspecific isotope analyses. As a proof of concept\, we selected androsterone\, a structurally simple steroidal androgen well suited to controlled experiments\, to evaluate whether SSIA can distinguish isotopic patterns arising from different precursor sources and chemical transformations. \n\nOur findings demonstrate that SSIA can resolve position-specific isotopic patterns obscured in conventional analyses. This capability establishes a high-dimensional isotopic fingerprinting framework\, enabling more precise interpretation of biomarker sources and transformation pathways. Extending this approach to geological biomarkers opens a new dimension in molecular geoscience\, with the potential to improve source attribution in complex petroleum systems\, refine oil–source correlations\, and enable more robust reconstructions of organic matter origins\, paleoenvironmental conditions\, and thermal histories. \n\nEarth Science Seminar — \n\nLecture portion of the EAPS graduate-level class 12.571\, covering current research in geophysics\, geology\, geochemistry\, and geobiology.

SUMMARY:[FISH] Qingwang Yuan (Pennsylvania State U.)
DESCRIPTION:“Unlocking Earth’s Potential for Subsurface Hydrogen Production”\nSubsurface hydrogen has recently emerged as a potentially low-cost and low-carbon source of energy. Depending on the host geological formation and the underlying generation mechanisms\, subsurface hydrogen production can be broadly categorized into two pathways: (1) in-situ hydrogen generation from petroleum reservoirs through thermochemical reactions\, and (2) natural and stimulated geological hydrogen (GeoH2) generation through water–rock reactions involving iron-rich formations. \n\nIn this talk\, I will first provide a high-level overview of these two emerging research areas and then focus on stimulated GeoH2 production from subsurface iron-rich rocks. I will discuss the fundamental mechanisms governing GeoH2 generation through serpentinization\, potential stimulation strategies\, and ongoing research in our group aimed at enhancing and quantifying GeoH2 production under dynamic subsurface conditions. \n\nSpecifically\, I will present results from a series of core-flooding experiments using both packed beds of rock powders and consolidated core samples containing engineered fractures over a range of temperatures. Experiments involving injection of pure water\, nickel-containing catalyst solutions\, and bicarbonate solutions were designed to investigate enhancement of GeoH2 generation through modification of fluid chemistry\, catalytic acceleration of water-rock reactions\, and increased reactive surface area. These flow-through experiments are complemented by autoclave-reactor studies\, enabling systematic comparison between closed-system and open-system hydrogen generation. \n\nBuilding on insights from these laboratory experiments\, I will discuss a simplified modeling framework that incorporates the effectiveness of stimulations to estimate field-scale GeoH2 generation rates and cumulative hydrogen yields. The model is further used to quantify the sensitivity of hydrogen production to key geological\, geochemical\, and stimulations parameters. Finally\, I will discuss how these results can guide experimental design\, identify key controls on stimulated GeoH2 production\, and inform the translation of laboratory-scale observations toward potential field-scale applications. \n\nDr. Qingwang Yuan is an Associate Professor in the Department of Energy and Mineral Engineering at Penn State University starting from August 2026. In 2020\, he joined Texas Tech University and established The Hope Group focusing on subsurface hydrogen production\, enhanced geothermal recovery\, and CO2 sequestration. He is a Co-founder and the President of the Association of Geological Hydrogen (AGH)\, a non-profit organization aiming to advance the global GeoH2 community. He worked as a Postdoc at Stanford University and University of Regina. He received his PhD degree from University of Calgary and MSc and BSc degrees from the China University of Petroleum (East China)\, all degrees in Petroleum Engineering. \n\nFriday Informal Seminar Hour — \n\nPostdoc-run seminar series within the Earth Resources Laboratory http://erlweb.mit.edu (ERL).

SUMMARY:[ESS] Pascal Audet (University of Ottawa)
DESCRIPTION:Deep Roots of a Mountain Belt: Lithospheric Structure and Mantle Dynamics Beneath the Canadian Cordillera\nThe Canadian Cordillera\, a vast Phanerozoic mountain belt from the US border to Alaska\, is classically attributed to terrane accretion\, subduction\, and strike-slip tectonics\, but its deep architecture and the geodynamics of the northern Canadian Cordillera (NCC) have been unclear\, fueling controversial models of its amalgamation and current tectonic deformation. New seismic data from the EarthScope USArray and other recent networks across Alaska and Yukon provide new constraints on its architecture and tectonic processes: the orogen is characterized by a shallow\, flat Moho\, with temperatures of ~800–900°C\, which can support high topography without a conventional crustal root. Rigid lithospheric elements—the buried Mackenzie craton and the Liard Transfer Zone—act as buttresses that localize deformation and shape the arcuate deformation front. The Tintina Fault\, a large-scale transcurrent fault\, cuts through the full lithospheric mantle\, displacing cratonic fragments. Furthermore\, depressions of the 410 and 660 km discontinuities beneath a slab window created by subduction of the Resurrection/Farallon spreading ridge suggest mantle transition-zone temperatures are 100–300 K higher than in the surrounding mantle. Overall\, a fossil divergent plate boundary provides a long-lived conduit for deep-mantle heat\, linking whole-mantle convection to a hot\, weak lithosphere and promoting long-term uplift of the Cordillera. \n\nEarth Science Seminar — \n\nLecture portion of the EAPS graduate-level class 12.571\, covering current research in geophysics\, geology\, geochemistry\, and geobiology. All members of the MIT community are welcome to join for presentations by guest speakers\, held approximately every two weeks during the term. \n\nContact: earth-science-seminar-info@mit.edu earth-science-seminar-info@mit.edu \n\nAttend Virtually: \nhttps://mit.zoom.us/j/94298370383 \n\nEAPS Calendar Detail Page: \nhttps://eaps.mit.edu/events/ess-pascal-audet-university-of-ottawa/
