TRACING RETROGRADE METAMORPHIC FLUIDS IN A SUBDUCTION ZONE USING LI: FRANCISCAN COMPLEX, CALIFORNIA
Centimeter-scale layers of eclogite and blueschist from Tiburon Peninsula, Franciscan Complex, CA were contrasted with a similarly layered sample from Dos Rios, CA. Eclogites from both localities have similar mineral ...
Lithium and delta7Li behavior during metamorphic dehydration processes and crustal evolution
Li isotopes have been used as a tracer of a wide range of geological processes, because the two stable isotopes of Li have significant relative mass difference and large elemental dispersion in Earth. In order to understand ...
Lithium and its isotopes as a tracer of fluid flow mechanisms in the Catalina Schist melange zone
Mélange zones are areas of highly mixed and deformed rock believed to form from shearing between subducting slab and peridotite mantle wedge. They have high -pressure/low-temperature mineral assemblages and contain a ...
CHARACTERIZING THE DURATION, PERIODICITY AND CHEMICAL IMPACT OF FLUID TRANSPORT IN THE SUBDUCTING SLAB: INSIGHTS FROM ISOTOPE GEOCHEMISTRY OF HIGH-PRESSURE METAMORPHOSED OCEANIC CRUST
Subduction zones are key loci of geochemical cycling and natural hazards on Earth including large earthquakes and explosive volcanic eruptions. Fluids produced during subduction are thought to play a role in all these ...
