Solid State Geochemistry: High-Resolution Transmission Electron Microscopy of Minerals

这项研究将利用高分辨率透射电子显微镜和互补技术来恢复存在于矿物结构扭曲、非化学计量、界面、沉淀、分层结构和其他“缺陷”中的信息。研究的主题包括：(1)与俄罗斯顺加还原环境有关的不寻常的富碳矿物；(2)绿泥石蚀变过程中形成的层间蛭石-蒙脱石；(3)非立方？黄铁矿，(4)海底玄武岩的岩浆成矿作用，(5)洛伦兹显微镜，(6)单位细胞尺度的化学成像。卓越的设施与同源学科的合作科学家的独特结合将有助于追求重要的矿物学发展和高分辨率的应用。

9706359 Buseck This research will utilize high-resolution transmission electron microscopy and complementary techniques to recover information that resides in the structural distortions, non-stoichiometry, interfaces, precipitates, gradational structures, and other "defects" in minerals. Topics to be studied include: (1) the unusual carbon-rich minerals associated with the reducing environments of Shunga, Russia, (2) interstratified vermiculite-smectite formed during chlorite alteration, (3) non-cubic ?pyrite, (4) maghemitization in ocean-floor basalts, (5) Lorentz microscopy, and (6) chemical imaging at the unit cell scale. The unique combination of an outstanding facility with cooperating scientists in cognate disciplines will help the pursuit of important mineralogical developments and applications of high-resolution.
