摘要
庄寨铅锌多金属矿矿体赋存于三叠系上统南梳坝组中下部钙质粉砂质泥岩与薄层状泥质灰岩接触带、二叠系砂子坡组下段碎裂状白云岩与丙麻组上段紫红色玄武质泥岩接触带附近构造破碎带及丙麻组上段紫红色玄武质泥岩之碎裂状白云岩内。矿床类型为构造热液型矿床,“硅钙二元结构面+构造破碎带”复合部位是主要的控矿成矿构造。
The ore bodies of the Zhuangzhai Pb-Zn polymetallic deposit occur in the tectonic fracture zones near thecontact zones between calcareous silty mudstone and thin-bedded argillaceous limestone of the middle-lower section of Upper Triassic Nanshuba Formation,and contact zones between cataclastic dolomite of the lower section of PermianShazipo Formationand purplish-red basaltic mudstone of the upper section ofPermian Bingma Formation,or within cataclastic dolomite of the uppersection ofBingma Formation.This deposit is of tectonic hydrothermal type,with the composite part of"Si-Ca binary structural plane and tectonic fracture zone"being the main ore-controlling structure.
