豫南铜多金属贵金属矿床类型及找矿前景

豫南地区发育着铜多金属及贵金属矿床，在空间上矿化与断裂构造破碎带密切有关，使“矿体、矿群、矿带”呈间距平行展布的特征。矿床可分为产于前寒武纪变质碳酸盐岩系中、产于变质中、基性岩系中和产于燕山期酸性侵入岩体内外接触带中三类铜多金属和贵金属矿床。提出了在围山城、银洞坡、刘山崖和杜家畈矿区外围以及银洞沟—马大庄、河嘴—驼店、犁铧寨—南湾—皇城山和南马畈—柳林等找矿远景区段。

TYPES OF COPPER POLYMETALLIC AND PRECIOUS DEPOSITS AND THEIR ORE PROSPECTS IN THE SOUTHERN HENAN PROVINCE

Copper polymetallic and precious deposits occur in the southern Henan provinee. Spacially their mineralizations are closely related to the fracture zone.The orebodies,ore deposit group and mineralization belt are charactered by parallel distribution as isospace distance.Deposits can be divided into three types occurred in Precambrian metamorphic carbonatite series,in metamorphic medium basic rock series,and in the inner and outer contact zone of the acid intrusion at Yenshan stage.The ore prospecting areas are put forward as follows,the surrounding areas of the known Weishancheng,Yindongpo,Liushanya and Dujiaban mining areas,as well as the Yindongpo-Madazhuang,Hezhui-Tuodian,Lihuazhai-Nanwang-Huangchengshan and Nanmaban-Liulin etc.
