The early magmatic stage of pegmatite formation is often subsequent to hydrothermal processes involving aqueous fluids, which leave their unique mineralogical overprint, like the crystallization of fine-grained albite, natrolite, zeolites, exotic carbonate minerals, and fibrous or spherulitic aegirine.In some cases, the chief mineral muster and texture are completely eradicated by late-stage hydrothermal reworking. These complex linkages of minerals are defined collectively as pegmatites or, to differentiate them from granite pegmatite counterparts, alkaline pegmatites.Its name is immaterial to its mineral composition. Its composition is the same as granite with copious quartz, feldspar, and mica. They may be referred to as granite pegmatites signalling their mineral composition. Others may also be feasible such as gabbro pegmatite, syenite pegmatite, diorite pegmatite and various other plutonic rocks combined with pegmatite.
