广东省鹤山市白云地铅锌矿矿床地质特征及成矿地质条件分析

The analyse on metallogenic geological conditions and prospecting mark of the Pb-Zn deposit in the Baiyundi mine in Heshan County, Guangdong Province

白云地铅锌矿处于中新生代三水断陷盆地南西缘,地处北东向恩平—从化深断裂与东西向高要—惠来深断裂及北西向西江大断裂三者交汇部位,区内构造活动强烈、岩浆活动频繁。矿体呈脉状产于近东西向及次一级北北东向、北西向断裂破碎带中,矿床主要构造和岩浆岩综合控制,初步认为本矿床成因类型为岩浆期后热液充填(交代)型硫化物矿床。

The Pb-Zn deposit in the Baiyundi mine is located in the southwestern margin of Sanshui fault depression basin in Mesozoic and Cenozoic, which is located in the intersection of Enping-Conghua NE to the deep fracture zone and Gaoyao-Huilai WE to the deep fracture and the Xijiang NW to the maior fracture. The structure activity is strong and the magmatic activity is frequent. The main orebody is vein shaped, and occurs in the fracture zone of NNE trending and NW trending faults near the East, The ore deposits are mainly controlled by tectonic and magmatic rocks. It is preliminarily considered that the genetic type of the deposit is magmatic hydrothermal filling（metasomatic） sulfide deposits.
