摘要
宁国市中溪地区奥陶纪地层中发现较具规模的金矿。该金矿受构造作用控制明显,具有构造角岩型特征,同时又有表现出层控的特点。金矿化体主要产于奥陶纪印渚埠组底部,与西阳山组的界线附近,其物质组分由钙质向泥质过渡。在印渚埠组中发现金矿体扩展了该区金矿的找矿空间,同时提供了新的勘查思路。
larger scale gold mine was found in ordovician strata in zhongxi area of ningguo city. The gold mine is obviously controlled by the tectonic action,and has the characteristics of constructing diagenetic type,and at the same time has the characteristics of layer control. The gold mineralization is mainly produced at the bottom of the Ordovician Indo Formation, near the boundary with the Xiyangshan Formation,and its material components transition from calcium to muddy. The discovery of gold ore body in the Injungbu Formation expanded the prospecting space of gold mine in the area and provided new exploration ideas.
