摘要
通过1:50000骑田岭花岗岩基单元—超单元填图,笔者从岩石学、岩石化学、暗色包体、微量元素、稀土元素和副矿物等特征研究入手,指出岩基的物质来源与成因,应是地壳物质重熔型,可能有少量幔源物质参与混熔,岩体的成岩方式,为岩浆侵入冷却而成。
Through 1:50000 scale unit--superunit geologic mapping of Qitianling granitic bathlith, proceeded from studies on petrological,petrochemical, trap rock inclusion, trace element, rare earth element and accessory mineral features, the author pointed out that the origin of the granitic bathlith belongs to crustal source material anatexis type, possibly with a little amount of mantle source material mixed in. The rock mass is formed by magma intruding and cooling.
