Is granite made from crystals or grains?
Granite is composed of numbers of individual mineral crystals and these crystals of individual minerals can be referred to as grains. Due to the formative processes involving granite, individual mineral crystals may not have what is popularly thought of as a crystal form, although they truly are mineral crystals. Grains could also be crystals or particles of other rocks which make up some sedimentary rocks. The grain size is part of the determination of the rock's texture: fine-grained, coarse grained, etc..
