Fractionation, Evolution, Petrogenesis and Mineralization of Laiziling Granite Pluton, Southern Hunan Province
详细信息   
摘要

///The Laiziling granite stock was emplaced in the early Yanshanian period. Its zircon U-Pb age is dated at (154~155) Ma. This granite pluton is characterized by enrichment in Li, Rb, Sn, W, Nb, Ta etc. rare metal elements, Pb, Zn etc. base metal elements and H2O, F etc. volatiles. A vertical zonation is well developed within a vertical distance of (450500) m. From the deeper level upwards to the top of the Laiziling Mountains peak, the following zones are successively observed: protolithionite granite zone, leucogranite zone, albite granite zone, greisen zone, massive quartz and pegmatoid stockscheider. The authors propose that the primary magma source of the Laiziling granite might be derived from the A-type Qitianling batholith, or a fractionated deeper magmatic chamber similar to the Qitianling granite.
