👉 Trachyandesite is a type of mineral that consists of grains or crystals embedded in a sedimentary rock. It is commonly found in rocks such as granite, schist, and gneiss, but it can also occur in other types of rock, such as basalt, feldspar, and quartzite. Trachyandesites are often associated with metamorphic processes that result in the formation of new mineral grains or crystals within the original rock.
