WebbTo identify pegmatite, first observe the individual grains of the rock. They should be crystalline and very large (1 cm across or more) and interlocking with one another. Look for quartz, feldspar, and mica, which are very common in pegmatites. There should be no visible porosity, banding, or layering.
