0318769SchieberThis grant provides partial support to the Indiana University Department of Geological Sciences for the acquisition of a state-of-the-art environmental SEM (ESEM) that has attachments for chemical microanalysis (EDS) and high resolution cathodoluminescence (SEM-CL). The low-vacuum imaging capabilities of the ESEM will foster new avenues of research on hydrated sedimentary rocks, clay minerals and zeolites without the need for conductive sample coatings. The new facility will support faculty and student research on early diagenetic processes in fine grained sediments, studies of the microfabrics of fault materials, and studies of the materials properties of zeolite minerals. The ESEM will also be useful for preliminary microtextural and compositional mapping of hydrothermal ore minerals and planetary materials prior to further quantitative microchemical analysis using an existing electron probe. Studies of petroleum reservoir rocks by researchers from the Indiana Geological Survey will also be facilitated by this new instrument.***

0318769 Schieber这笔赠款为印第安纳州大学地质科学系提供部分支持，用于购买最先进的环境SEM（ESEM），该SEM具有化学微量分析（EDS）和高分辨率阴极发光（SEM-CL）附件。 环境扫描电镜的低真空成像能力将促进对水合沉积岩、粘土矿物和沸石的研究的新途径，而不需要导电样品涂层。 新设施将支持教师和学生对细粒沉积物中早期成岩过程的研究，断层材料微结构的研究，以及沸石矿物材料特性的研究。 环境扫描电镜也将是有用的初步微观结构和成分映射的热液矿石矿物和行星材料之前，进一步定量微化学分析使用现有的电子探针。 印第安纳州地质调查局的研究人员对储油岩的研究也将得到这一新仪器的便利。
