These laboratories house a broad range of shared equipment for the initial steps of preparing rock samples. Numerous SES research groups use these labs, before completing more specialized procedures in their own facilities. Equipment is available for rock sawing, polishing, coring, crushing, grinding, powdering, sieving, washing, drying, separating, concentrating, etc. (formerly Rock Preparation and Mineral Separation Labs)
Our research seeks to understand what controls mineral-fluid reaction rates and how these rates are linked to long and short-term carbon cycling. I use natural laboratories that span gradients in time, hydrology, biology and parent material to establish the relationships between geochemical processes and hydrologic/climatic, geomorphic and geophysical processes. To quantify reaction rates I couple radiogenic and stable isotopic tracers with reactive transport modeling approaches.
We comprehensively examine the evolution of the Earth's crust using highly integrated geochronologic approaches conducted in a wide spectrum of analytical facilities that are all housed within the School of Earth, Energy & Environmental Sciences. Our highly collaborative research provides fundamental data to many disciplines throughout the geosciences, including tectonics, geodynamics, petrology, geochemistry, geomorphology, sedimentology, stratigraphy, paleontology, and paleoclimatology.
Earth history and the evolution of life, and the interactions between the biosphere and the geosphere.
Nuclear materials, such as those used in nuclear reactors and waste forms, are subjected to extreme environments on long timescales. Nuclear reactors need to operate safely for decades, and next generation reactors will only require even more durable materials than those currently in use. Nuclear waste, which currently has no long term disposal plan in the United States, is required to be safely isolated for one million years. Designing and testing materials used for waste packaging is critical to the overall goal of safe storage.
Our research combines macro-scale, field-based work on the stratigraphy and paleontology of carbonate platforms with micro-scale, laboratory-based work on the petrography and geochemistry of individual limestone samples and mineral phases. In addition to field and laboratory study, I also compile literature-based data and use theoretical models to help constrain interpretation of field-based data and to determine the extent to which local biotic patterns reflect global processes.
The Sedimentary Geochemistry and Paleoenvironments Project (SGP) is an open, community-oriented, database-driven research consortium that seeks to address questions of environmental evolution across Earth history through statistical analyses of the sedimentary geochemical record.
The Sedimentary Geology Research Group at Stanford University studies a variety of problems in basin analysis, deep-water systems, process sedimentology, micropaleontology, and Archean environmental conditions.
The focus of our research is on fundamental issues of structure and dynamics in crystalline, glassy, and liquid silicates and oxides, and on glass-forming liquids in general. Our goal is to relate experimental measurements of atomic-scale processes to macroscopic properties of interest to the earth sciences (including mineralogy, igneous and metamorphic petrology, volcanology and geochemistry), materials sciences, and physical chemistry.
