Material composition and internal structure of granite-pegmatite bodies of the Mamsko-Chuyskaya mica province

Abstract
In the Mamsko‑Chuyskaya mica province, many deposits are confined to the bodies of the so‑called giganto‑migmatites, representing a system of bedded and cross‑cutting pegmatite bodies, so they were studied by many geologists. One of the first researchers was N.V. Petrovskaya, who called these bodies giganto‑migmatites. In subsequent years, all geologists unanimously noted that more than half of the pegmatite varieties involved in the structure of giganto‑migmatites are granitic rocks. They were named granite‑pegmatites.
