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.

提出的研究计划的目的是提高对银在各种热液环境中如何形成、运输、分区和沉淀的理解。将进行一系列实验来检验：1)低温银合金熔体的存在；2)用表面增强拉曼光谱（SERS）间接测量银熔体包裹体的熔化温度；3)银同位素作为地温计和流体示踪剂的可行性。
