广东省韶关市武江区赤老顶锑矿成矿条件浅析

Analysis on metallogenic conditions of chilaoding antimony deposit in Wujiang District,Shaoguan City,Guangdong Province

勘查区所处大地构造为粤北“山字型”构造脊柱南缘—瑶山复背斜的东侧、一六多金属矿田南部,区内构造发育,具有良好的成矿地质条件,找矿潜力巨大。矿床以层控型为主,兼有断裂构造控矿的特点。锑矿层呈似层状或透镜状赋存于上泥盆统天子岭组含矿硅化岩中。

The geological structure of the exploration area is located in the southern margin of the"mountain shaped"structural spine in northern Guangdong,the eastern side of Yaoshan anticline and the southern part of the No.16 polymetallic ore field.The structure in the area is well developed,with good metallogenic geological conditions and great prospecting potential.The ore deposits are mainly stratabound and have the characteristics of ore controlling by fault structures.Antimony deposits occur in the ore bearing silicified rocks of the upper Devonian Tianziling formation in the stratoid or lenticular form.
