9725248 Bodnar拟议研究的目的是开发热液金刚石砧室（HDAC），用作加压流体包裹体阶段。HDAC然后将与合成流体包裹体技术结合使用，以获得PVTX数据的地质上重要的系统H2O-CO2氯化钠在温度和压力范围以外的常规实验技术通常用于确定PVTX性能的流体。试验研究的结果证明了使用HDAC作为加压流体包裹体阶段的可行性，以通过加热气体来防止这种包裹体的非弹性体积变化 在高静水围压下的含盐包裹体的HDAC。在这项研究中，HDAC将被用来作为一个加压流体包裹体阶段，以确定P-T位置的H2O-CO2溶线和斜率的等值线在压力高达约7-9千巴。该研究还将导致开发一种协议，用于最有效地使用HDAC作为加压流体包裹体阶段，用于研究目前无法在传统的一个大气压加热阶段中研究的天然流体包裹体。

9725248 Bodnar The objective of the proposed research is to develop the hydrothermal diamond anvil cell (HDAC) for use as a pressurized fluid inclusion stage. The HDAC will then be used in conjunction with the synthetic fluid inclusion technique to obtain PVTX data for geologically-important system H2O-CO2 NaCl at temperatures and pressures beyond the range accessible with conventional experimental techniques normally used to determine PVTX properties of fluids. Results of a pilot study document the feasibility of using the HDAC as a pressurized fluid inclusion stage to prevent non-elastic volume changes for such inclusion by heating the gas salt-bearing inclusions under a high hydrostatic confining pressure in the HDAC. In this study, the HDAC will be used as a pressurized fluid inclusion stage to determine the P-T location of the H2O-CO2solvus and the slopes of isochores at pressures up to approximately 7-9 kbar. The research will also result in the development of a protocol for the most efficient use of the HDAC as a pressurized fluid inclusion stage for the study of natural fluid inclusions that currently cannot be studied in the conventional one-atmosphere heating stage.
