The author postulates the formation of a primary and then a secondary magmatic chamber. The primary chamber is the formation site of the original magma. From this chamber it rose to the secondary chamber in the crustal sections of the earth, where it differentiated by gravity into its various magmatic fractions. From the secondary chamber these fractions were intruded or extruded or both in the upper crust. As examples of his theory he describes and quotes the geology of the alkalic basaltic rocks of the northwestern Talas-Alatau spurs. M.A. Klugman
