The convergence of world class computational (NERSC) and characterization (ALS) resources has made it possible for ESD scientists Sergi Molins, Carl Steefel, Jonathan Ajo-Franklin, and Li Yang together with CRD scientist David Trebotich to develop and apply Next Generation pore scale reactive transport models to the problem of geological CO2 injection and sequestration in the subsurface.

ESD’s Barbara Romanowicz and others have detected previously unknown channels of slow-moving seismic waves in Earth’s upper mantle, which help explain “hotspot volcanoes” that give birth to island chains such as Hawaii and Tahiti.

ESD’s Shaun Brown and Don DePaolo were part of an investigative team that used oxygen isotope analyses (δ18O) of 16 quartz-epidote pairs from late Cambrian (Betts Cove and Mings Bight, Newfoundland), Ordovician (Thetford Mines, Québec, Canada) and Cretaceous (Troodos, Cyprus) ophiolites to calculate theδ18O of the hydrothermal fluids from which they crystallized.

A team of investigators (including former ESD Division Director Don DePaolo) show that the growth rate dependence of Sr and Mg incorporation into calcite, as well the inhibitory effects on calcite growth of both incorporating and non-incorporating ions, can be predicted with an ion-by-ion crystal growth model where ion attachment is confined to kink sites on the crystal surface.

In a recently published paper, ESD geochemist Glenn Waychunas (and others) shows the existence of pressure-induced polyamorphism (the existence of a substance in different amorphous modifications, akin to polymorphism in crystalline materials) in hydrated ACC, and the formation of “aragonitic” ACC upon a decrease in the molar volume.

To test capillary-scaling-based predictions, ESD’s Tetsu Tokunaga and his investigative team (including ESD’s Jiamin Wong, Jong-Won Jung, Tae Wook Kim, Youngman Kim, and Wenming Dong) developed a high pressure Pc(Sw) controller/meter, allowing accurate Pc and Sw measurements.
