The Wadi Hodein area contains a wide variety of late Precambrian igneous and metamorphic rocks, represented by gneisses, serpentinites, metagabbros, metasediments, metavolcanics, metagabbro-diorite, granodiorite and granitoids. The Wadi Hodein metavolcanics (WHV), including G. Khashab and G. El Anbat, represent one of the significant metavolcanic suites in the southern part of the Nubian Shield...

Two ancient asbestos mines, one near Karystos, Greece, and the other southeast of Mount Troodos, Cyprus, were located in what we now know to be ophiolite terrane. Evidence suggests that asbestos was discovered and utilized in Cyprus, perhaps as long as 5,000 years ago, for manufacture of cremation cloths, lamp wicks, hats, and shoes. Some of the adverse health effects of asbestos became known o...

Libby, Montana is the site of a large vermiculite deposit that was mined between 1920 and 1990 to extract vermiculite for commercial applications such as insulation, gardening products, and construction materials. The Libby vermiculite deposit also contains amphibole minerals including tremolite, actinolite, richterite, and winchite. Historically, Libby mine workers experienced high exposures t...

Five main apatite deposits from the Moroccan Central High-Atlas —including Anemzi, Tirrhist-Inouzane, Tassent, Ait-Daoud-Toumliline and Tasraft— have been investigated through integrated field, petrographic, mineralogical, geochemical studies. The ore occurs as veins, few mm to several cm thick, spatially associated with syenite-quartz monzonite (dominant) monzodiorite-gabbrodiorite bodies empl...

We report two experiments using 13 mineral and rock samples exposed to a complex synthetic Venus atmosphere composed of nine gases for durations 30 11 days conducted the NASA Glenn Extreme Environments Rig (GEER). Examination our run products scanning electron microscope equipped with an energy dispersive spectrometer reveals secondary minerals predominantly formed from reactions Fe Ca in solid...
