内蒙古布敦花岩浆杂岩体成岩成矿特征初析

A Dicussion on Metallogenetic Characteristics of Magmatic Complex in Budunhua, Inner Mongolia

布敦花杂岩体位于大兴安岭铜多金属成矿带中段，东临嫩江深大断裂。布敦花铜矿床的形成与杂岩体多次侵入活动密切相关，岩体具多期次侵入作用特点，成矿作用是在岩浆不同侵入期次过程中充填、交代围岩的过程中发生的，矿床成因类型属与杂岩体关系密切的斑岩型铜矿床。

Budunhua magrnatic complex is situated in the coddle of copper poly’rnetallic metallogenetic belt in Daxinganling and east side of Nen Eiver deep major fracture. Budunhua copper deposit has close relationahip with complex that has character of the multiple intrusion. The its metallogenesis is taken place in process of filling-replacement sourrounding rocks during different magmatic intrusion stages. The deposit’s genesis type is considered to be porphyry copper deposit.
