中文摘要
Tivey 9314005 这项研究将采用各种技术来确定从热液凸缘矿床中采集的样品的特征。PI将确定孔隙度、矿物学、孔隙流体和硫矿物的结构和化学性质。这些数据将与其他人测量的温度和流体成分相结合,并用于计算机模型中,以量化质量和能量通量。该项目应提供有价值的见解形成的法兰,这是最好的模拟已知的块状硫化物矿床。
英文摘要
Tivey 9314005 This study will apply a variety of techniques to characterize samples taken from hydrothermal flange deposits. The PI will determine porosity, mineralogy, texture and chemistry of pore fluids and sulfur minerals. These data will be combined with temperature and fluid composition measured by others, and used in a computer model to quantify mass and energy fluxes. The project should provide valuable insights into the formation of the flanges, which are the best analog known for massive sulfide ore deposits.
