Fluid Inclusion Microthermometry Stage

这项提议用于购买替换设备，用于对矿物中流体包裹体的相变进行非破坏性温度测量。流体包裹体是在热液矿物结晶时捕获的液体或气体的微观小块，因此代表了这些矿物生长的流体的实际样品。测量相变温度，如冰融点，可以提供有关这些流体的盐度和一般组成的信息，而高温测量提供了对其原始温度的最低估计。利用本提案中要求的设备获得的测量相对简单、快速和廉价，所产生的数据通常是热液矿床形成和碳氢化合物成熟度和运移研究的关键组成部分。特别是，在进行更详细的分析工作之前，微温测量是必不可少的初始步骤，例如对流体包裹体溶质的粉碎-浸出分析(如在共同申请者格里森的实验室中进行的)。我们的许多研究生已经并将在他们的学习中使用这种设备。

This proposal is for the purchase of replacement equipment used for making non-destructive temperature measurements of phase transitions in fluid inclusions in minerals. Fluid inclusions are microscopic pockets of liquid or gas trapped within hydrothermal minerals at the time of their crystallization, and therefore represent actual samples of the fluids from which these minerals grew. Measurement of the temperature of phase changes such as ice melting points can provide information about the salinity and general composition of these fluids, while high temperature measurements provide minimum estimates of their original temperatures. The measurements are relatively simple, quick, and cheap to obtain with the equipment requested in this proposal, and the resulting data are typically a key component in studies of the formation of hydrothermal ore deposits, and the maturation and migration of hydrocarbons. In particular, microthermometric measurements are an essential initial step before more detailed analytical work, such as crush-leach analysis of fluid inclusion solutes (as carried out in co-applicant Gleeson's lab), can be conducted. Many of our research students have been using and will use this equipment in their studies.
