Collaborative: Chimneys Forming from Vent Fluids at 231 deg to 405 deg C: Examination of Critical Point Phenomena, Mineral Assemblages, and Implications for Microbial Haitats

该项目将研究海底热液喷口沉积物中存在的矿物组合范围和可能的微生物环境，并观察热液系统中的矿物沉淀在接近临界点的条件下是如何受到影响的。重点是在烟囱内不同的排气口微生物栖息地收集的29对排气口流体/排气口固体样品，这些样品受到温度和排气口流体组成差异的影响，绘制烟囱中不同微生物群可能茁壮成长的电话，记录水临界点附近相分离对矿物沉积的影响。

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.
