湖南省新龙锑矿区矿床地质特征及找矿标志
|
摘要
新龙锑矿区内矿床主要受构造控制,表现为断裂和褶皱,断裂为F1导矿断裂及其下盘的一系列NNW—NW、NNE、NE、NWW向的次级容矿断裂,背斜核部及正常翼赋存有较好的锑矿床。近年来,矿区资源储量仅约2 000 t,属资源危机矿山。结合新龙矿区的矿物岩石特点与地层中Sb的富集情况,认为锑矿床是由岩浆热液对Sb高背景值地层中的Sb进行活化、萃取并运移至有利的构造空间堆积形成。根据矿区地质特征及成矿条件、控矿因素的分析,认为矿区有利的找矿标志为地层岩性、构造、蚀变及物化探异常,此外,矿区边深部找矿潜力较大,宜进一步开展工作。
The deposits in Xinlong Sb mining area are mainly controlled by structures,they are characterized as fractures and folds,fractures in the mining area are consisted by F1 ore-transmitting fracture and the NNW—NW,NNE,NE,NWW trending secondary ore-containing fracture,the better antimony deposit is occurred in the normal wings of anticline and anticlinal core. In recent years,the resources reserves of the mining area is only almost 2 000 t,it is belongs to the resources crisis mine. Based on analyzing the mineral rock characteristics and the enrichment characteristics of Sb in strata in the mining area,it is show that Sb in the strata with high Sb background value is activated and extracted by magmatic hydrothermal and migrated to favorable structural space to form the antimony deposit. The analysis results of metallogenic conditions and ore-controlling factors in the mining area show that stratigraphic lithology,tectonics,alteration,geophysical and geochemical anomalies are the favorable prospecting indicators of the mining area,besides that,the prospecting potential of the edge and depth of the mining area is huge,it is necessary to conduct further prospecting and exploration work.
