摘要
甘肃省成县大安山铅锌矿位于西成铅锌矿田属秦岭铁铅锌(铜)多金属成矿带的西延部分。西成矿田位于秦岭造山带西段腹地的中秦岭南缘华力西-印支期褶皱带与南秦岭北缘印支褶皱带的衔接部位。先后发现了大中型铅锌矿床多处。大安山铅锌矿含矿层位为西汉水组第二岩性段第二层,赋矿层位为含泥炭质钙质板岩与绿泥绢云石英千枚岩之含泥炭质钙质板岩层间破碎带。
The Daanshan lead-zinc deposit in Chengxian county,Gansu province is located in the west extension part of the qinling iron,lead,zinc(copper)polymetallic metallogenic belt.The Xicheng ore field is located at the junction of the huali-indo-chinese folding belt at the southern margin of the middle Qinling mountains and the indo-chinese folding belt at the northern margin of the southern Qinling mountains.Many large and medium-sized lead-zinc deposits have been discovered.The ore-bearing horizon of Daanshan lead-zinc deposit is the second layer of the second lithologic member of the west hanshui formation,and the ore-bearing horizon is the interpeaty calcareous slab fracture zone between the peaty calcareous slate and the peaty calcareous slate.
