摘要:
河南内乡夏馆—西峡二郎坪一带金矿床(点)广泛分布,成矿类型多样,产出条件复杂,岩体与 围岩接触带以及中元古代和早古生代地层中都有金矿形成。根据成矿物质、成矿流体来源和成矿机制, 将产于接触带和地层中的金矿体分为5种类型,它们是在火山、火山沉积和正常沉积等不同背景下,由 岩浆热液、变质热液或地下水热液叠加改造(再造)形成的,每类矿床都经历了多期多阶段成矿过程,以 后期热液交代、充填成矿为主。构造对金矿形成有明显控制作用,区域性深大断裂控制金成矿带,二级 韧脆性剪切带控制金矿床分布,三级层间破碎带、断裂裂隙带和接触带构造控制矿体就位。构造热液 的叠加改造或再造主导了成矿作用。
Abstract:
From Xiaguan to Erlangping in Henan gold deposits(mineralized pits)occur extensively; they vary in mineraliza- tion type and their conditions of occurrence are complex. Gold deposits formed in intrusive bodies and contact zone between intrusive bodies and wall rocks, and in Mesoproterozoic and early Palaeozoic strata. The authors divide gold deposits in con- tact zones and strata into five types on the basis of ore source, metallogenic fluid origin and mineralization mechanism. The gold deposits are formed because of magma hydrothermalism, metamorphic hydrothermalism and hydrothermal superimpo- sion on the background of volcanism, volcanic sedimentation and normal sedimentation. Each type of gold deposits is experi- enced multiphase and polystage mineralization, but mainly late hydrothermal replacement and packing mineralization. Tec- tonics controls the formation of gold deposits distinctly. The regional deep fault belt controls gold deposits belt. Second-or- der ductile-brittle shear belt controls the distribution of gold deposits; three-order tectonics of interlayer fractured zones, fracture crack zones and contact zones control the ore forming. In all, the main mineralization was hydrothermal superimpo- sion or regeneration.
