Acquisition of a Heating/Freezing Stage, Microscope, and Video System for Fluid Inclusion Research

小行星9709783 该补助金提供20，000美元，作为购买加热/冷冻台以及显微镜和视频系统的部分费用支持，用于研究流体包裹体的物理和化学性质。最近资助的一项研究提案（ESTA-9614683）将依赖于使用该仪器产生的数据来限制流体包裹体捕获压力，以增加同位素和岩石学数据，用于解释热液流体成分的时间演变和随后的围岩蚀变，这些蚀变导致蒙大拿州Butte斑岩矿石存款的形成。 此外，这一系统将与基性岩斑晶和捕虏体中流体包裹体所含原始氦的同位素分析结合使用，以深入了解洋中脊和大洋热点玄武岩的岩石成因。 将从该系统中受益的其他项目包括，在交代蒸发岩矿床中的流体包裹体的研究和碎屑沉积岩中的成岩石英增生中捕获的流体包裹体的研究。 ***

9709783 Dilles This grant provides $20,000 as partial support of the costs of acquiring a heating/freezing stage coupled with a microscope and video system for use in studies of the physical and chemical properties of fluid inclusions. A recently funded research proposal (EAR-9614683) will rely on data produced using this instrument to constrain fluid inclusion trapping pressures to augment isotopic and petrologic data in the interpretation of the temporal evolution of hydrothermal fluid compositions and subsequent wall rock alteration that led to the formation of the porphyry ore deposit at Butte, Montana. In addition, this system will be used in combination with isotopic analyses of primordial helium contained in fluid inclusions trapped in mafic phenocrysts and xenoliths to yield insight into the petrogenesis of mid-ocean ridge and oceanic hot spot basalts. Other projects that will benefit from this system include, studies of fluid inclusions in metasomatized evaporite deposits and studies of fluid inclusions trapped in diagenetic quartz overgrowths in clastic sedimentary rocks. ***
