| 摘 要： | 栖霞地区金矿点繁多，但仅有两处规模近中型的金矿床。根据对马家窑、台前金矿床特征及成矿地质条件的分析，并与招莱地区金矿床进行类比，认为栖霞地区金矿成矿条件与招莱地区基本相似，但由于重熔花岗岩体侵位较深，含矿热液未能运移至浅部，因而热液矿床赋存深度较大，地表及浅部金矿呈现“矿点多，规模小”的分布特点。栖霞地区深部找金潜力很大，重点勘查区应为隐伏的深熔、重熔花岗岩发育区，以及ＮＥ、ＮＮＥ向断裂及其下盘次级断裂所在部位。

| Abstract: | Gold spots widely spread in Qixia area,but occur only two medium scale gold deposits which are Majiayao and Taiqian. According to the analysis of their deposits characteristics and mineralization conditions,and analogging them with the gold deposits in Zhaolai area,it is recognized that the granitoid intrued deeply,the mediumlarge scale gold deposits occur in deep part (unfound) and in surface of shallow part occur small scale gold deposits of gold spots in Qixia area. The gold mineralization condition between Qixia area and Laizhou area is quitely similiar, so it has a high potential to prospect gold deposits in deep crust in Qixia area. The major prospecting areas should be the ones where develop deepmelt granite,remelt granite,faults trending in NE and NNE, and their subgrade on their lying wall faults. |
