The paper presents original data on the inner structure, mineralogy, and geochemistry of the Late Paleozoic Burgasy quartz syenite massif in western Transbaikalia and mafic microgranular enclaves (MME) in its rocks. The composition of the mafic microgranular enclaves is close to that of phase-1 monzonitoids of this pluton, but the enclaves are not ...

Abstract This work evaluates the origin of mafic microgranular enclaves in granites through a process of magma splitting at the boundaries of ascent conduits, where an intermediate, high-silica andesite magma separates into two magma systems without a continuous change, one of Qz-dioritic composition and high-crystal content and another one of ...

The microgranular mafic enclaves included in granitoid bodies are of high petrological interest, inasmuch as they represent records of previous magmatic activity and/or episodes of mafic magma input into evolving granitoid systems. In this paper we report major, trace clement and preliminary Sr isotopic data for a series of mafic inclusions coming from
