What is felsic metavolcanic rock?

Felsic metavolcanic rock is a type of metamorphic rock derived from the alteration of felsic volcanic rock, such as rhyolite or dacite, under conditions of heat and pressure. These rocks are typically rich in silica and aluminum, giving them a lighter color and lower density compared to mafic rocks. The metamorphic process may result in the formation of minerals like quartz, feldspar, and mica, contributing to their characteristic texture and composition. Felsic metavolcanic rocks are often found in regions with a history of volcanic activity and tectonic processes.
