Summary
[edit]DescriptionRhyolite pmg ss 2006.jpg |
English: Photomicrograph (crossed polarized light) of rhyolite volcanic rock. The width of the view is approximately 3 mm. The rock shows porphyritic texture, and contains vesicles. The main phenocrysts are quartz and potassium feldspar. Groundmass is composed of quartz, potassium feldspar, volcanic glass (partly crystallized to spherulitic aggregates), iron hydroxides and chlorite. Vesicles have quartz growing on their walls, forming miarolic structure.
