摘要
河南省某地周庵铜镍矿床为岩浆深成熔离作用和岩浆期后热液作用叠加的多期次成矿的岩浆矿床。矿区内的构造主要表现为褶皱构造,断裂构造不发育,矿区内分布的岩浆岩体主要为燕山期侵入的超基性岩体。该矿床的地质特征表明其形成是多种地质因素综合作用的结果,其中,岩浆成分和大地构造因素起主导作用。但是,同化作用、挥发性组分作用以及岩浆的多期多次侵入作用也是不可缺少的因素。
Zhouan cupro nickel deposit is in Henan Province, which is a superimposed multi--phase mineralization magmatic deposit of magmatie subnate differentiation by liquation and magmatie hydrothomalism. The structure in ore area is mostly showing up to folding tectonics, faulted structures are not developed, the magmatie body distributed in ore area is mainly Yansbanian intruding uhrabasic body. The geologic character of this deposit indicate that its formation is a result of a variety of geological factors comprehensive function, in which magma composition and tectonic structure play a leading role. However, assimilation constituent volatilization and multiple episodes of magma instruction are indispensable factors.
