代家庄铅锌矿位于中秦岭华力西褶皱带南亚带西段,为西成铅锌矿带的西延部分,受层位控制明显,泥盆系上统龙鳞桥组是铅锌矿化有利含矿层位,该含矿层含炭千枚岩、板岩铅锌含量普遍较高,矿体赋存于其与生物灰岩的接触部位,矿体形态、规模与沉积古地理环境有关,根据矿体地质特征、控矿因素,提出本矿床属含炭泥—粉砂质低温热水沉积成因。 The Daijiazhuang lead-zinc deposit is located in the western segment of the southern sub-belt of the Hurixi fold belt in the Central Qinling Mountains and is the west extension of the Xicheng lead-zinc ore belt. It is obviously controlled by the horizon. The Devonian Longlongqiao Formation is a lead-zinc mineralization Favorable ore-bearing layer, the ore-bearing layer contains phyllite, the slate is generally high in lead and zinc, and the ore body exists in the contact area with biological limestone. The ore body morphology and scale are related to the sedimentary paleogeographic environment. According to The geological characteristics of ore bodies and the ore-controlling factors suggest that the deposit belongs to the genesis of low-temperature hot-water sediments with carbonaceous muddy silt.
