摘要
通过对桑木场地区铅锌矿地质特征研究,区内矿床(点)受NE向构造控制明显,次级正逆断层都显示出了明显的容、控矿特征。构造复杂段内的低序次张性断裂或扭张性断层、断层交汇处往往形成陡矿体,而褶皱构造的倒转翼、倾伏端等处的层间剥离、层间破碎带常赋存缓矿体。围岩蚀变以白云石化和重晶石化为主。根据该区铅锌矿独特的矿床地质特征,建立找矿模式。
According to the study of geological characteristics of the Pb-Zn deposits in Sangmuchang area,it shows that those deposits are obviously controlled by the NE structures.Secondary normal and reverse faults display obvious features of containing and controlling the ore body.The steep ore body is formed in tensional faults and shear-tensinal faults of lower order and fault interjunction area in the structural complex sections.The gentle-dip ore body is hosted in the zone of interlayered fractures and fissures in the inverted limb and plunging part of fold.Wall rock alterations are mainly dolomitization and baritization.The prospecting model is established on the basis of the unique geological characteristics of Pb-Zn deposits in the area.
