MINERALOGY AND PETROLOGY OF THE BRNJICA GRANITOIDS (EASTERN SERBIA)

Contributions to mineralogy and petrology

High-silica topaz-bearing rhyolites of Cenozoic emplaced as domes, lava flows or shallow intrusions. They age are widely distributed across the western USA and may also contain Fe-Mn garnet, beryl, bixbyite, pseudoMexico. They are characteristically enriched in fluorine brookite, hematite and fluorite in miarolitic cavities or with(>0.2 wt.%) and incompatible lithophile elements (e.g. Li, in th...

Mineralogy and Petrology of Stardust Particles Extracted from the Walls

Introduction: Since the return to Earth of the Wild 2 comet samples by the Stardust mission, most of the studies have been performed on terminal particles located at the end of the deceleration tracks. However, the major fraction of the cometary material is unevenly distributed along the track walls [1,2]. Particles within samples extracted from the walls show strong collectinduced thermal alte...
