Secondary-quartzite

This page is currently not sponsored. Click here to sponsor this page.
A medium to low-temperature metasomatic rock mainly composed of quartz with subsidiary high-alumina minerals, such as pyrophyllite, diaspore, alunite and kaolinite. Common accessories include fluorite, dumortierite and lazulite. Secondary-quartzites are associated with volcanic and subvolcanic rocks of rhyolitic to andesitic composition. Normally they form as replacements of acid igneous rocks and more rarely of sedimentary rocks. They may host mineral deposits of alunite, pyrophyllite, Au, Cu, Sb Hg.
