摘要
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。
Daijiazhuang lead - zinc ore is located in the west part of central Qinling folds belt. It is the west part of xihe - chengxian lead - zinc ore - forming belt, and controlled strictly by the beds. It occur in the contact part of D3L^2-2 and D2L^3, and contain the deal of lead - zinc is always high in this bed. The ore comformations and ore scales is related with the olde sedimentary environment. Because the sedimentary environment formed the minor structures, so the lead - zinc ore bodies isn＇t large. By studying on the geological features, the controlled factors, and the mechanism of formations, the genetics of the ore are discussed.
