Pegmatite

Pegmatites occur in all parts of the world and are most abundant in rocks of relatively great geologic age. Some are segregations within much larger bodies of intrusive igneous rocks, others are distributed in the rocks that surround such bodies, and still others are not recognizably associated with igneous rocks.

Gener- ally, a fractured aggregate particle will be found at the bottom of the hole with the other part of the aggregate still adhering to the point of the popout cone. Most popouts are about 25 to 50 mm (1 to 2 in.) wide; however, popouts caused by sand particles are much smaller, and very large popouts may be up to 300 mm (1 ft) in diameter.
