WebbRhyolite is a volcanic rock with high silica content. Rhyolite has silica content similar to that of granite while basalt is compositionally equal to gabbro. Intermediate volcanic rocks include andesite, dacite, trachyte, and latite. [citation needed] Pyroclastic rocks are the product of explosive volcanism. They are often felsic (high in silica). Webb13 apr. 2024 · The lavas include basalt, andesite and rhyolite, whereas the volcaniclastic rocks primarily include tuff and breccia. In addition to extrusive igneous rocks, a few intrusive rocks are present in the basin, the main lithologies of which are granitic porphyry and granite (Fig. 9).
