Silver deposits, melt-inclusions, isotopes, and thermobarometry

The objective of the proposed research program is to develop an enhanced understanding of how silver is speciated, transported, partitioned, and precipitated in a variety of hydrothermal environments. A series of experiments will be undertaken to test: 1) the existence of low-temperature silver-alloy melts; 2) the indirect measurement of melting temperatures of silver melt inclusions by Surface Enhanced Raman Spectroscopy (SERS); and 3) the feasibility of a using silver isotopes as a geothermometer and a fluid tracer.
