摘　　要：为更好地了解湘阴地区建筑用砂卵石矿的矿石质量和资源潜力,通过野外勘查、实验室测试等方法,分析该地区建筑用砂卵石矿矿石质量特征、沉积特征和成矿规律。研究发现:矿床为河相沉积矿床,矿层赋存于第四系中更新统白沙井组下段;砂卵石主要由砂、卵石及泥质组成,经过长时间的物理和化学作用,形成了建筑用砂卵石矿;覆盖层砂土含砂率低,洗砂开采不经济,推荐其用途为城镇开发建设路基填料、场地填方。In order to research the ore quality and resource potential of the sand pebble mine for construction in Xiangyin area,the ore quality features,sedimentary features and metallogenic regularity of the sand pebble mine were analyzed by field survey and laboratory test.It was found that the deposit is a fluvial sedimentary deposit,and the ore layer exists in the lower member of Baishajing Formation of Middle Pleistocene in the Fourth system.The sand pebble is mainly composed of sand,pebble and mud.After a long time of physical and chemical action,sand pebble ore for construction is formed.The sand content of the cover layer is low and the sand washing mining is not economical.It was recommended the sand pebbleas subgrade filling and site filling for urban development and construction.
