Abstract
The article deals with the mineralogical peculiarities of the Upper Cretaceous basalt-basaltic andesite and dacite-rhyolite complexes of the Gazakh trough and the crystallization conditions of mineral parageneses. Separated mineral paragenesis characterizes the stages of crystallization of primary alloys of rock complexes in intermediate magmatic chambers. Mineral paragenesis consists of olivine-chrome spinel-clinopyroxene, olivine-clinopyroxene-plagioclase-titanium magnetite, orthopyroxene-clinopyroxene-plagioclase-titanium magnetite-amphibole, orthopyroxene-clinopyroxene-plagioclase-titanium magnetite-quartz, biotite-plagioclase-titanium magnetite-quartz. The process of crystallization differentiation played a leading role in the evolution of rock compositions of the basalt-basaltic andesite and dacite-rhyolite complexes.
