The earlier units contain abundant mafic micro-enclaves, and the petrographic study of the enclaves indicates the crust-mantle mixing origin of the granitic magma.
A granitic rock composed chiefly of quartz and mica.
Remelting magmatism, hydrothermal circulation drived by heat from granitic bodies and concentration of water in thermal fluid may be the most important factors to mineralization of gold.
The Dashankeng gneiss located in the northeastern Dabie mountains is composed mainly of potassium feldspar, plagioclase and quartz with minor hornblende, biotite and allanite, belonging to monzonitic granitic in composition.
The tin mineralization dies not depend on wall rocks in a certain extent, butchiefly relies on orogenic granitic belts of the obduction side of the continental crust.
Granitic gneiss is the most extensive geologic unit in the Sulu ultra-high pressure metamorphic belt and the age of protoliths of granitic gneiss is Neoproterozoic era.
A batholith has been defined as a huge intrusive mass of granitic rock.
The granitic gneissic rock series contained the early rich-agpaitic TTG-granites and the later rich-potash granites.
The research on geochemical characteristics and isotope age suggests that the deposit belongs to a magma-metasomatic pegmatite type deposit related to Fufang and Huitong granitic mass in genesis.
The meta-somatic processes predominating in the granitic rocks in Zhejiang Province include alkali enrichment caused by metasomatism, i. e. seriatization, microclirization, and silicification.
