摘要
天合兴碱长花岗斑告为同期多次侵入的复式脉体群,岩石矿物组合、结构构造、岩石化学及地球化学等特征相似,副矿物相同。为S型花岗岩类。成岩初始物质来源于地壳。
The Tianhexing alkali-feldspar granite-porphyry is a swarm of composite veins by contemporaneous and multiple intrusion. The mineral assemblage, structure and texture of rocks,petrochemical and geochemical characteristics, etc. are very similar, the accessory minerals are the same, belonging to Stype granitic rocks. The initial materials for diagenesis are derived from the crust.
