摘要: 青海省西秦岭成矿带成矿条件优越, 成矿带内金、铜、汞、钨、锑、砷、石灰岩等矿产主要分布在青海南山—泽库Au-Ag-Cu-Pb-Zn-W-Sb-Fe-As-石墨-花岗岩-盐类-干热岩成矿亚带(IV-28-2)和苦海—作母沟Hg-Au-Pb-Zn-Sb-W-泥炭成矿亚带(IV-28-3)内。金属矿产空间展布上主要产出于构造活动强烈, 深大断裂活动、火山活动、中酸性岩浆侵入活动和沉积地层变形-变质改造较为普遍的地区。并呈现出区域集中、带状、近等距性分布的特点。研究区内34 个矿种的成因类型以岩浆作用矿床和含矿流体作用矿床为主, 其次为沉积作用矿床, 成矿时代以三叠纪和第四纪为主, 石炭纪—三叠纪古特提斯洋演化阶段形成了以接触交代型、岩浆热液型金(银)、铜、铅锌、钨、砷, 浅成中-低温热液型金、锑、铜、铅锌、汞、砷为主的内生矿床, 以化学沉积型石灰岩为主的外生矿床。以区内地质构造演化与成矿时空分布特点为基础, 依据成矿系列理论, 共厘定出西秦岭成矿带成矿系列组3 个, 矿床成矿系列9 个, 矿床成矿亚系列12 个, 矿床式13 个。在成矿远景区的基础上进一步指出了区内的找矿方向。Abstract: The metallogenic conditions of west Qinling metallogenic belt in Qinghai Province are abundant.Gold, copper, mercury, tungsten, antimony, arsenic, and limestone are mainly distributed in the Qinghainanshan–Zeku Au-Ag-Cu-Pb-Zn-W-Sb-Fe-As-graphite-granite-salt-dry-hot rock metallogenic subzone(IV-28-2) and Kuhai–Zuomugou Hg-Au-Pb-Zn-Sb-W-peat metallogenic Ore subzone(IV-28-3).Predominantly, metal minerals are produced in areas with strong tectonic, deep and large fault, volcanic, and intermediate-acid magmatic intrusion activities, as well as deformation-metamorphism transformation of sedimentary strata.Accentuating characteristics of regional concentration, banded, and equidistant distribution.The main genetic types of 34 minerals within west Qinling are: magmatic and ore-bearing fluid deposits, secondary sedimentary deposits, metallogenic epoch is mainly Triassic and Quaternary, Carboniferous to Triassic Paleotethyan evolution stage formed contact metasomatism, magmatic hydrothermal gold (silver), copper, lead-zinc, and tungsten.Epigenetic meso-cryogenic hydrothermal deposits are abundantly contained Au, Sb, Cu, Pb, Zn, Hg and As, whereas epigenetic deposits are dominated by chemically deposited limestone.The evolution of geological structure, the spatial and temporal distribution of mineralization in the area, and the theory of metallogenic series suggest three metallogenic series groups, nine ore deposit series, 12 ore deposit subseries and 13 ore deposit types are located in the west Qinling metallogenic belt.Metallogenic prospective areas highlight the prospecting direction in the district for further explorations.
