闪长玢岩

铅、锌矿化多与二长花岗岩有关，铁铜矿化多与黑云母花岗岩关系密切，而铜矿化多与闪长岩（或闪长玢岩）有关。

Pb-Zn mineralization in the studying area is usually related to adamellite , and Fe - Cu mineralization to biotite granite , while Cu mineralization to diorite or diorite porphyrite .

后者由闪长岩、石英闪长玢岩、安山岩、安山玄武岩组成。

The latter is composed of diorite , quartz diorite porphyrite , andesite , andesite basalt .

闪长玢岩和花岗闪长斑岩具有同源岩浆房，属于同源异相的产物。

Diorite porphyry and granodiorite porphyry have the same comagmatic room , belonging to homology-phase of the product .

该岩体主要由石英闪长玢岩、石英二长斑岩和花岗闪长斑岩组成，与铜矿化关系密切。

The intrusion mainly consists of quartz diorite porphyry , quartz monzonite porphyry and granodiorite porphyry , and has close relationship with the copper mineralization .

在Haker图解中，石英闪长玢岩和石英闪长岩样品与镁铁.超镁铁岩石样品构成良好的分异演化趋势，说明二者均为镁铁质岩浆演化末期的产物。

Samples of quartz diorite porphyry , quartz diorite and mafic rocks compose a well fractionate trend on the Harker diagrams , which indicate that the quartz diorite porphyry and quartz diorite should be products formed at the end of the evolution of mafic magma .
