摘要
胶东地区内生金矿的成矿溶液是深溶岩浆连续分异演化而成.成岩成矿作用产生于同一个地质时代,并可分为包括岩浆岩体、脉岩、矿床及其诸成矿阶段在内的早晚两期成矿系列.早期的内生金矿为主生金矿期.晚期为共生—伴生金矿期.早期成矿系列生成时代于156～136Ma之间,晚期为124～100Ma.
The ore-forming fluid of endogenous gold deposits in east Shandong province is derived from the successive differentiation of anatectic magma. The diagenesis and mineralization processes occur in the same geological time and they can be divided into two ore-forming series (early and late stages) including magmatie rocks, vein rocks, ore deposits and ore-forming periods. The primary gold deposits are attributed to the early stage while the intergrown and associated gold mineralization belong to the late stage.
