构造-蚀变填图在贵州泥堡金矿床的初步实践
|
摘要
黔西南泥堡金矿床属于滇黔桂"金三角"地区的大型微细浸染型金矿床之一,是非岩浆热液成矿作用的典型代表。通过对泥堡金矿区开展1∶10000大比例尺构造-蚀变填图,查明了与金矿化密切相关的硅化、褐铁矿化、黄铁矿化及少量萤石化、毒砂化、辉锑矿化、方解石化等围岩蚀变的空间展布规律,厘定了矿区控矿构造格架为F1逆冲断层及其牵引形成的二龙抢宝背斜,以及枢纽北西向与北东向褶皱叠加所形成的穹隆构造。并据此提出了泥堡金矿找矿靶区,即位于玉家坪以南的乡道旁、次级逆断层与背斜构造组合样式发育区。
The Nibao gold deposit is one of the large Carlin-type gold deposits in the"golden triangle"of southwestern Guizhou Province, and it is typical for mineralization of non-magmatic hydrothermal fluid. Based on the 1∶10000 large scale structure-alteration mapping, the authors detected the main alterations comprising silicification, ferritization, pyritization with minor fluoritization, arsenopyritization stibnitization and carbonatization and their spatial distribution, and revealed that the ore-controlling structures are structural assemblages of reverse fault (F_1) and Erlongqiangbao anticline, and dome structures formed by superposed folds with northwest and northeast extending hinge. Furthermore, the authors hold that the prospecting targets of the Nibao gold deposit lie near the Yujiaping Village where the reverse faults and anticlines are well developed.
