Impurity elements in fluorite crystals from granite pegmatites of Kazakhstan
Authors:
Abstract
Pegmatite-bearing granite massifs of Kazakhstan are composed of Alaskite granites of essentially potassic (microcline) composition. Pegmatite bodies containing fluorite and quartz crystals are located in granites. Pegmatites, as a rule, have an irregular isometric shape. The size of the bodies varies from 5-10 to 20-25 m in the largest cross-section. According to their internal structure, pegmatites belong to the fully differentiated type. They are composed of a quartz core concentrically surrounded by a blocky, feldspar zone and further by a zone of graphic granite. Cavities with fluorite and quartz crystals are usually located at the lower contact of the quartz core.
