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).

Large Igneous Provinces (LIPs) are manifestation of large-volume magma (>0.1 × 10 6 km 3) transfer from the Earth’s mantle to the crust within a time span <1−10 Myr (main eruption within 1–5 Myr) that spreads across an area >0.1 × 10 6 km 2 (Bryan and Ernst, 2008); Sheth (2007) proposed an areal extent of ≥5 × 10 4 km 2.
