摘要
河南省桐柏金矿带位于桐柏山北麓。金矿带构造为桐——商韧性剪切带的一部分;出露地层为中元古界龟山岩组;岩浆岩有中——基性岩、花岗岩、脉岩。龟山岩组地层中Au、Ag、As、Cu、Pb等为主要成矿成晕元素。金矿床异常轴向分带序列(由上至下)为:Sb—As—Ag—Au—Cu—Pb—Ni—Mo。金矿床异常轴向分带,具正向分带特征,没有出现反向分带和逆向分带,表明不同成矿阶段形成的矿体为同位叠加,因此轴向分带序列用于成矿预测具有较好的效果。
Tongbai Gold belt in Henan province lies in the north of Tongbai mountain.. The structure of gold belt belongs to Tong-Shang ductile shear zone; On the top of formation is turtle rock group Yuan in the ancient world; There are basic rock, granite and The vein rocks in the Magmatic rocks. In the layer of Turtle rock, the main Ore-forming elements into a halo are Au, Ag, As Cu Pb and so on. The sequence of Go）d deposits＇ Abnormal axial （from top to bottom） are： Sb-- As--Ag--Au--Cu--Pb--Ni Mo. The sequence of Gold deposits＇ Abnormal axial have a feature of Positive zoning, no P, everse zoning or Converse zoning, which shows Ore body in different Metallogenic stage is a stacking. Because of this, there will be a good result if axial zonality sequence is put into use of precticting the oreforming.
