Yamansu Formation of the Lower Carboniferous comprises the main ore-bearing formation in the Xiaoshitouquan ore district. 摘要小石头泉矿区主含矿层为下石炭统雅满苏组第二亚组，火山穹隆及伴生断裂为主要的控矿构造。
In the li-ght of analysing all factors of controling the distributionof ore deposit, a prediction of distribution of Cu-Fe ore de-posit was made. 综合各种控矿因素对区内铜铁矿的分布做了预测分析。
