About alkaline igneous rocks

Abstract

The author dwells on the issue of differentiation of primary planetary magma (see article). In addition to the factors that acted and determined magmatic differentiation during the period of cooling of the planet and its solidification, other factors subsequently acted that continued the work of their predecessors. Such factors must be recognized as water and the atmosphere after their appearance on earth. These figures continued to differentiate the rocks, separating bases and acids and concentrating them at individual points, for example, depositing thick layers of limestones, quartz sandstones, alkali chlorides and other compounds. These concentrated bases and acids, absorbed again by the magma, may have been the reason for the violation of homogeneity and excessive enrichment in bases, which led to the appearance of basic rocks, both alkaline and alkaline earth. Standing on this point of view, we can, based on a single primary, for example, granite magma, explain all the diversity of magmas that gave rise to the emergence of igneous rocks on the earth's surface, with which we are gradually becoming acquainted.
