摘要
本文对夹皮沟地区水系砂金矿床的地质特征及资源潜力进行了系统研究。通过野外调查、样品分析和资料整理,详细阐述了该区的地质背景、砂金矿床特征及分布规律。研究结果表明,老牛沟砂金矿床主要赋存于第四纪冲积层中,金矿物以自然金为主,粒度较细。矿体呈带状分布,受地形和水系控制明显。资源量估算显示该区具有较大的找矿潜力,为今后砂金矿勘探开发提供了重要依据。
The geological features and resource evaluation of the aquifer gold deposit in Jiapigou area were systematically studied in this paper.Through field investigation,sample analysis and data collection,the geological background,features and distribution of placer gold deposits in this area are described in detail.The results show that the Laoniugou placer gold deposit mainly occurs in Quaternary alluvium,and the gold minerals are mainly natural gold with fine grain size.The orebodies are distributed in bands and are obviously controlled by terrain and water system.The estimation of resources shows that the area has a large prospecting potential,which provides an important basis for the exploration and development of sand gold deposits in the future.
