Features of the formation of muscovite crystals in pegmatite veins

Abstract

As is known, there are many works on the issues of pegmatite genesis, including the processes of formation of large muscovite crystals in them. Despite this, various researchers until very recently have very contradictory opinions on a number of the most important patterns of mica formation. Therefore, the ideas about the patterns of spatial distribution of muscovite in pegmatite rocks, about the nature of the distribution of lication to depth, etc. are also contradictory. The absence of a definite solution to these main practical issues in a number of cases complicates the correct choice of methods for the prospective assessment of veins, exploration and exploitation of muscovite deposits. Let us recall that at present there are the following ideas about the genesis of large muscovite crystals.
