摘要
沃溪金锑钨矿床赋存于元古界板溪群马底驿组中、上段紫红色板岩中.划分出逆断层、层间断层、成矿后断层和褶皱等4类构造.区内见有层间石英脉、网状石英脉、节理石英脉3类矿体.金主要赋存于黄铁矿和辉锑矿等硫化物中.矿化与褪色化、中细粒黄铁矿化和硅化有关.认为矿床是沉积一变质热液改造成因,并提出了论据和找矿方向.
The Woxi Au-Sb-W ore deposit is present in slate, purplish red in colour, located at the mediumand upper members of the Madiyi Formation of the Proterozoic Banxi Group. Four kinds of structuresare recognized: reverse fault, interformational falt, post mineral fault and fold. In the mining area orebodies occur as interbeded quartz vein, network quartz vein or joint quartz vein. Gold is mainly foundin pyrite and antimonite. Mineralizations bear a relationship with decolourization, the medium to finegrained pyritization and silicilication. It is believed that the ore deposit is polygenetic, being of sedimento metamorphic and hydrothermal-reformation origins. Grounds for explaining the origions of the deposit and exploration guide are also put forward in this paper.
