摘要： 石头滩铜矿位于钦杭成矿构造带中段的衡阳盆地的南缘，沿衡阳盆地周缘分布有多个大中型铜矿床，成矿条件优越。为给衡阳盆地的铜矿找矿提供指导，对矿区区域地质背景、矿床地质特征进行研究分析，得出铜矿层产于白垩系神皇山组褪色化砂岩中，当层间破碎带发育时有利形成高品位的铜矿体，表明矿区成矿时期有深源物质的加入，或与盆地卤水有关，属层控低温热液砂岩型铜矿。

Abstract: Shitoutan copper deposit is located in the middle part of qinhang metallogenic structural belt，It belongs to the southern margin of Hengyang Basin.The metallogenic conditions in this area are superior，Because there are many large and mediumsized copper deposits along the periphery of Hengyang basin.In order to provide guidance for the exploration of copper deposits in Hengyang basin,the regional geological background and geological characteristics of the deposits are studied and analyzed.It is concluded that the copper deposits occur in the fading sandstone of the shenhuangshan formation of Cretaceous system.it is favorable to form highgrade copper ore bodies When the interlayer fracture zone develops.It indicates that the ore deposits are of deepseated materials or related to the brine of the basin,which belongs to stratabound lowtemperature hydrothermal sandstone Type copper deposits.

Key words: Sandstone copper deposits,Light colored beds,Interlayer fracture zones, Geological characteristics, Genesis of deposit
