DISCUSSION ON GENESIS OF LINGLONG GRANITE

Systematic study on geology, mineralogy, petrology, petrochemistry, REE and isotopic geochemistry reveals that gneissic granite and monzonitic granite in Linglong granitic body are derived from Neoarchean Lower Proterozoic TTG rock series. strong fracturing of Yishu fault gave rise to large heat flow leading to partial melting materials. Diapirism of the melts took place under tectonic pressure to form the complex Linglong granitic batholith.
