摘　　要：九台区大青山金矿位于北东向与北西向断裂交汇部位,金矿化主要赋存于白垩系下统营城组中酸性火山岩系中,是该区近年来新发现的一处金矿。笔者通过总结该矿点的地质特征,认为该金矿点是一处岩浆喷溢低温热液型金矿。该矿点是在地质、物化探密切配合下发现的,其发现过程对该地区今后的金矿勘查找矿工作具有重要意义。Daqingshan gold deposit in Jiutai District is located at the intersection of NE and NW faults.The gold mineralization mainly occurs in the middle-acid volcanic rock system of Yingcheng Formation of Lower Cretaceous,which is a newly discovered gold deposit in recent years.By summarizing the geological features of the gold deposit,the author thinks that the gold deposit is a magmatic effusion epithermal type gold deposit.This deposit was discovered under the close cooperation of geology,geophysical and geochemical exploration,and its discovery process is of great significance for the future gold exploration and prospecting in this area.
