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.

9706359 Buseck这项研究将利用高分辨率透射电子显微镜和补充技术来恢复信息，驻留在结构扭曲，非化学计量，界面，沉淀物，梯度结构，和其他“缺陷”的矿物。 将研究的主题包括：（1）与俄罗斯顺加还原环境有关的异常富碳矿物;（2）蚀变作用形成的间层蛭石-蒙皂石;黄铁矿，（4）海底玄武岩中的磁化作用，（5）洛伦兹显微镜，以及（6）单位细胞尺度的化学成像。 杰出的设施与相关学科的合作科学家的独特组合将有助于追求重要的矿物学发展和高分辨率的应用。
