石英二长斑岩

斑岩的主要岩石类型为花岗闪长斑岩、二长花岗斑岩、石英二长斑岩。

The main rock types of the porphyries are granodiorite-porphyry , monzonitic granite-porphyry and quartz monzonitic porphyry .

石英二长斑岩侵入于前奥陶纪松多岩群和石炭-二叠系来姑组中，并被帕那组火山岩呈火山沉积不整合覆盖。

The quartz-monzonite porphyry intrusived in the Pre-Ordovician Songduo Group and Carboniferous-Permian Laigu Formation , unconformably covered by the volcanic rocks of Pana Formation .

根据杂岩体相互之间的接触、穿插、包裹等关系，厘定他们形成的先后顺序为正长闪长岩、霓辉正长岩、石英二长岩、花岗斑岩、正长斑岩。

According to the complex interspersed 、 cutting 、 wrapping relations among all the complex , we can determine their order of formation which is syenodiorite to aegirine-syenite to quartz-monzonite to granite-porphyry to syenite porphyry .

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 .
