概要地介绍了阿力安萨铜矿床区域成矿地质背景和矿床特征，区内共发现两个铜矿化层、4条铜矿体。铜矿体均产于上第三系渐新统第二岩性段含铜砾岩、砂砾岩层中，矿体呈似层状、层状、透镜状，其形态严格受地层控制，矿床成因类型为沉积砂砾岩型。火山活动为成矿带来了大量的物质来源与成矿条件，第三系大孔隙度的砂岩、砂砾岩为成矿提供了空间和场所。
概要地介紹瞭阿力安薩銅礦床區域成礦地質揹景和礦床特徵，區內共髮現兩箇銅礦化層、4條銅礦體。銅礦體均產于上第三繫漸新統第二巖性段含銅礫巖、砂礫巖層中，礦體呈似層狀、層狀、透鏡狀，其形態嚴格受地層控製，礦床成因類型為沉積砂礫巖型。火山活動為成礦帶來瞭大量的物質來源與成礦條件，第三繫大孔隙度的砂巖、砂礫巖為成礦提供瞭空間和場所。

this paper summarily introduces the Alianza metallogenic geological background and characteristics of the copper deposit area , where two copper layer 4 copper ore body areas were found .Copper ore body are produced in the second li-thologic section copper tertiary Oligocene conglomerate , gravel strata, with layered, stratified, lenticular form, its configu-ration is strictly controlled by strata , deposit genetic types of sedimentary sand conglomerate type .Volcanic activity for met-allogenic belt a lot of material sources and metallogenic conditions , tertiary large porosity of sandstone and glutenite provid-ed ore-forming space and place .
