Porphyry

Igneous Rocks

Porphyry is any of various granites or igneous rocks with coarse-grained crystals such as feldspar or quartz dispersed in a fine-grained, generally aphanitic matrix or groundmass. The name describes a texture, large crystals set in a finer background, rather than one fixed composition.
