Compositions of micas in peraluminous granitoids of the eastern Arabian shield - Implications for petrogenesis and tectonic setting of highly evolved, rare-metal enriched granites
Compositions and pleochroism of micas in fourteen peraluminous alkali-feldspar granites in the eastern part of the Late Proterozoic Arabian Shield are unlike those of micas (principally biotite) in most calc-alkaline granitoid rocks. Compositions of these micas are distinguished by elevated abundances of Li2O, F, and numerous cations and by low MgO abundances. These micas, constituents of highly e

Campground talk and slide show on volcanoes for Chiricahua National Monument
The slides and the accompanying script presented here are based on a campground presentation at Chiricahua National Monument in 1994. Examples of eruptions at active volcanoes are used to help the audience visualize events that took place in the National Monument 27 million years ago. This presentation stresses the following themes: 1) The National Monument lies on the flank of an ancient volcano
