Modeling Calcite Growth Among Ions1 min read

The concentrations of Sr, Mg, and other elements in calcite are
widely used to infer the conditions of mineral growth. However, such
inferences are dependent on the mechanisms that govern the incorporation
of minor constituents into the calcite lattice during growth. 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. This model should be widely applicable
for understanding the impurity content of a large range of sparingly
soluble minerals that form by precipitation from aqueous solutions.

The research was done as part of the Center for Nanoscale Control of
Geologic CO2
, a Basic Energy Sciences Energy Frontier Research Center.
General support for isotopic geochemistry is also provided by Chemical
Sciences, Geosciences and Biosciences Division, Office of Science,
Office of Basic Energy Sciences, of the U.S. Department of Energy under
Contract No. DE-AC02-05CH11231.

  Scientists from the Energy Geosciences Division have begun working with European partners on three new geothermal research projects through the Department of Energy’s membership in GEOTHERMICA, a transnational consortium that combines the in-country financial resources and research expertise of 15 participating countries to demonstrate and validate novel concepts in geothermal energy use. This marks the…

EESA Senior Scientist Talks Earthquake Building Resilience1 min read

Berkeley Lab senior scientist David McCallen leads a subproject called Earthquake Sim, or EQSIM, for the DOE’s Energy Exascale Computing Project. He is also professor and director of the Center for Civil Engineering Earthquake Research in the Department of Civil and Environmental Engineering at the University of Nevada, Reno. McCallen recently spoke with Scott Gibson of…

EESA Scientist Coauthors New Comprehensive Guide on Removing CO2 from the Atmosphere2 min read

January 18, 2021

Berkeley Lab researchers are working on ways to sequester more carbon in soil, including through agricultural practices. (Credit: Berkeley Lab) Scientists say that any serious plan to address climate change should include carbon dioxide removal (CDR) technologies and policies, which makes the newly launched CDR Primer an especially vital resource, says Berkeley Lab scientist Margaret Torn, one…
