Feature Composition of the Basic Mass of Kimberlites Yakutiya

Kimberlite pipes, dykes, veins and sills quite often represent the rocks which were altered to various degree by postmagmatic and hypergene processes. Generated at this new formations are referred to secondary minerals, which are main rock-forming components, composing the basic mass of rocks. Distinction of kimberlite bodies is conditioned by intensity of development and evenness of distribution of dominating secondary minerals, their associations and varieties (calcite, dolomite, lizardite, chrysotile, phlogopite, chlorite, pyroaurite and others). It has been established that processes of serpentinization, carbonatization, chloritization and brucitization in each diatreme have individual character, leading to diversity of kimberlite types
