乐东县荣山乡金矿化点 位于乐东县城 附近 矿化点出露地层为上白垩统报万组上段,地层产状平缓,局部有平缓的小褶皱,产状80°∠30°, 240°∠5°。矿化点位于光明向斜北西翼。区内构造主要为光明向斜的次级小褶皱及断裂。断裂为张性,是金矿化的容矿构造。断裂走向北北西,倾向南西西,倾角65°。 矿化点见两条石英脉,延长660m,厚1~2m,赋存于上白垩统报万组上段地层中,严格受近南北向断裂控制。北段为含金石英脉,长170m,厚0.91m,产状70°∠75°。含金石英脉主要由玉髓组成,并有后期细粒石英脉穿插。采2个样品,含金2.08g/t、1.81g/t,平均含Au1.95g/t。 矿石具变余隐晶结构,角砾状结构。矿石金属矿物为自然金、褐铁矿、非金属矿物为玉髓石英。 石英脉型金矿 R 工作程度:踏勘 Ledong County Rong Shan gold point 位于乐东县城 附近 Located in Ledong County near 矿化点出露地层为上白垩统报万组上段,地层产状平缓,局部有平缓的小褶皱,产状80°∠30°, 240°∠5°。矿化点位于光明向斜北西翼。区内构造主要为光明向斜的次级小褶皱及断裂。断裂为张性,是金矿化的容矿构造。断裂走向北北西,倾向南西西,倾角65°。 Mineralization strata are the upper Cretaceous group, gentle strata, locally flat small folds, the occurrence of 80 degree angle 30 degrees, 240 degrees angle 5 degrees. Mineralization is located in Guangming North West Wing syncline. Area is the main structure in secondary syncline folds and faults in the light. The fracture is tensile, and it is the ore hosting structure of gold mineralization. The fault strike NNW, inclination angle of 65 degrees west southwest. 矿化点见两条石英脉,延长660m,厚1~2m,赋存于上白垩统报万组上段地层中,严格受近南北向断裂控制。北段为含金石英脉,长170m,厚0.91m,产状70°∠75°。含金石英脉主要由玉髓组成,并有后期细粒石英脉穿插。采2个样品,含金2.08g/t、1.81g/t,平均含Au1.95g/t。 The mineralization points see two quartz veins, extend the 660m, thick 1 ~ 2m, and occur in the upper Cretaceous strata in the upper Cretaceous strata, strictly controlled by the near North and South fault. The northern section of auriferous quartz veins, 170m long, 0.91M thick, the occurrence of 70 degree angle 75 degrees. Auriferous quartz is mainly composed of chalcedony, and late fine quartz veined. 2 samples were collected, containing 2.08g/t, 1.81g/t, with an average of Au1.95g/t. 矿石具变余隐晶结构,角砾状结构。矿石金属矿物为自然金、褐铁矿、非金属矿物为玉髓石英。 Variable structure with more than Yinjing ore and brecciated structure. The metal minerals are native gold, limonite, nonmetallic minerals are quartz chalcedony. 石英脉型金矿 Quartz vein type gold deposit R R 工作程度:踏勘 Work: reconnaissance
