东秦岭灵山岩体岩石谱系单位类埃达克质花岗岩及其成因和构造环境意义
The lithodemic units of adakite-like granite on genetic Types and tectonic settings for the Lingshan Pluton, East Qinling
摘要
Abstract
Lingshan Pluton is located in two sides of the Tongbai-Shangcheng Fault, which is the south Qinling metamorphic belt of East Qinling orogenic belt. According to the internal contact relation and structure differ-ences, Lingshan Rock stage divided into four main units as well as another three independent units. Lingshan granite show high silica- alkali, potassium-rich , low magnesium, poor calcium alkaline series. The high total REE is rightward incline, and the features of trace elements are rich in large ion lithophile elements (K, Rb, Ba). while the high field strength elements (Zr, Hf, P, Ta, Nb, Ti) are depleted. Lingshan granite is syntectic S-type with the geochemical characteristics of I-type and adakite-like granite, which was formed in the arc-continent post collision (anorogenesis) tensional environment.关键词
