This project will examine the range of mineral assemblages and possible microbial environments present within seafloor hydrothermal vent deposits, and observe how mineral precipitation in hydrothermal systems is affected at near criticl point conditions. Focus will be on 29 selected pairs of vent fluid/vent solid samples collected at a diversity of vent microbial habitats within chimneys are affected by differences in the temperature and composition of the vent fluid, map pones in chimneys where different groups of microbes could thrive, document the effects of phase separation near the criticl point of water on mineral deposition.

该项目将研究海底热液喷口矿床内存在的各种矿物组合和可能的微生物环境，并观察在接近临界点的条件下热液系统中的矿物沉淀如何受到影响。重点将是在烟囱内的各种喷口微生物生境中收集的29对选定的喷口流体/喷口固体样品，这些样品受到喷口流体温度和成分差异的影响，绘制不同微生物群体可能茁壮成长的烟囱中的池塘，记录水临界点附近的相分离对矿物沉积的影响。
