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.
