摘　　要：彝良沙木沟石英砂岩矿赋存于泥盆系中统缩头山组中,属陆源碎屑来源滨海相沉积型石英砂岩矿床,单斜层状产出。沿矿体走向和倾斜方向均具较大的找矿潜力。受上扬子陆块隆起区控制,为古陆隆起滨海前滨带反复冲洗沉积形成。矿石中Fe_(2)O_(3)含量略大于一般工业指标,其他指标与一般工业指标要求一致,其矿石可达到平板玻璃用硅质原料一级品要求。The Yiliang Shamugou quartz sandstone deposit is located in the Middle Devonian Suotoushan Formation,and belongs to the coastal sedimentary quartz sandstone deposit of terrigenous clastic source.There is great prospecting potential along the strike and inclined direction of the ore body.Controlled by the uplift area of the upper Yangtze block,it is formed by repeated flushing deposits in the coastal foreshore zone of the ancient land uplift.The content of Fe_(2)O_(3) in the ore is slightly higher than the general industrial index,and the other indexes are consistent with the general industrial index requirements.The ore can meet the first-class requirements of siliceous raw materials for flat glass.
