MAGMATIC DEPOSITS ARE ACCUMULATIONS OF MAGMATIC MINERALS. THEY ARE CHARACTERISED BY THEIR CLOSE RELATIONSHIPS WITH INTERMEDIATE OR DEEP SEATED INTRUSIVE IGNEOUS ROCKS. THEY CONSTITUTE EITHER THE WHOLE IGNEOUS MASS OR A PART OF IT OR MAY FORM OFFSET BODIES. THEY ARE MAGMATIC PRODUCTS THAT CRYSTALLISE FROM MAGMA.
A pegmatite is an igneous rock, formed underground, with interlocking crystals usually larger than 2.5 cm in size (1 in). Most pegmatites are composed of quartz, feldspar and mica, having a similar silicic composition as granite.
