摘要
五台-恒山地区的网状脆性断裂系统控制了中生代花岗岩类及其有关的金、银、多金属矿床的分布。中生代过渡同熔型花岗岩类是成矿的驱动力和成矿物质的母源。次火山岩是岩浆体系分熔侵入-喷发过程中最后集中成矿热液的载体,具有直接的找矿意义。该区中生代次火山岩型矿床与本区太古宙变质热液金矿在成矿地质背景、地球化学特征上具有明显的差异,说明了它们成矿物质来源的不同。
Anastomosing brittle fracture system at Wutai Hengshan region controls the distribution of Mesocoic granites and related Au Ag and polymetal deposits. The transitional Mesozoic syntectic granite drove metallogenesis and supplied materials. Subvocanics is the final carrier of hydrothermal fluid of magmatism thus is the prospecting target. The Mesozoic subvocanic type ore deposits and the Archean greenstone belt type of metamorphic hydrothermal Au deposits are varied in geochemistry and geological background and source materal.
