Structure and genesis of written granites in pegmatite veins
Authors:
Abstract
Graphic granites by the peculiarity of their structure have long attracted the attention of researchers. It is known that these rocks are similar to ordinary granites in their chemical and mineral composition, but all the quartz in them is enclosed within feldspar crystals in the form of numerous correctly oriented inclusions. The latter often resemble the pattern of ancient graphics. This peculiarity of the rock structure determined their name: runites, Hebrew stone, graphic pegmatites, pegmatite and the most accepted in our literature - graphic granites. Graphic granites are part of various geologic formations. They are known in dikes of acidic igneous rocks, in the apical parts of granite massifs, as part of strata of deeply metamorphosed rocks such as gneisses and others. The most spectacular and coarse-grained samples of written granites are found in pegmatite veins. It was here that they were studied in detail, and their first descriptions are more than a century and a half old. Since then a great deal of work has been devoted to the study of graphic granites and especially to a discussion of the genesis of these rocks.
