不列颠哥伦比亚省的矿床成因研究是根据1200多个矿床的资料进行的.这些资料包括所记录的金属与金属矿物、沉积岩与火山母岩的年龄和岩性以及任何有关的花岗岩类侵入体的性质.对这些资料的分析确定了斑岩矿床金属的双峰态来源.铜、钼源于原生花岗岩类熔融体,铜/钼比值则反映了此熔融体的成分.铅、锌、银、金产于斑岩侵入体周围的脉中,这些脉的金属含量受脉围岩的岩性控制.岩百学的制约意味着花岗岩类主要是深源地壳熔融成因.这样,我们就运用斑岩的分布与各不相金属比值来确定地壳深部构造图,因此就构成了构造模式.两个主要的火山-深成弧(海岸的:侏罗纪-早第三纪;Takla:三叠纪)产于两个俯冲带上.伴生底板的深熔作用产出了含铜斑岩.山间带的铜-钼斑岩是由混合火山岩、火山碎屑岩及碎屑沉积岩的深熔作用而产生的.这些岩石是在侏罗纪时期沉积于由两个岩浆弧圈闭的洋壳碎片上的.
A study of the genesis of the deposits in British Columbia is based on data from more than 1,200 deposits, including the age and lithology of recorded metal and metal minerals, sedimentary and volcanic rock, and the nature of any pertinent granite intrusions. Analysis of these data identified the bimodal source of the metal from the porphyry deposits, copper and molybdenum originated from primary granite-like melts, and the copper / mol ratio reflects the composition of the melt. Lead, zinc, silver, The porphyry intrudes into the vein around the body, and the metal content of these veins is controlled by the lithology of the surrounding rocks.The restriction of the rockery means that the granites are mainly derived from the melting of the deep source crust, so we use the distribution of porphyry The two major volcano-deep arcs (coastal: Jurassic-Early Tertiary; Takla: Triassic) are produced in two Subduction zones.The copper-bearing porphyries are produced by the deep melting of the accompanying floor.The copper-molybdenum porphyry in the mountain area is produced by the deep-melting of mixed volcanic rocks, pyroclastic rocks and clastic sedimentary rocks, The rock was in Jurassic Deposited on the oceanic crust by the two fragments of magmatic arc traps.
