摘　　要：针对甲龙矿区的成矿地质条件、蚀变特征等,应用卫星遥感技术对该区的成矿信息进行了综合解译和提取,指出了进一步的找矿方向。遥感构造解译结果显示,甲龙矿区发育一直径约2.5～3km的大型环形构造,两个直径约1km的小环形构造相交于大型环形构造内。北东向构造为矿区主导构造,次为北西西-近东西向构造,与环形构造均具有较好的空间相关关系。遥感蚀变信息与环形构造关系密切,在环形构造里面及其近外围,尤其是在环形构造与线性构造的相交部位以及环形构造里面的线性构造部位矿化蚀变更为强烈,是该区的有利找矿预测区。According to the geological conditions and alteration characteristics of ore-forming in Jialong metallogenic area,the further ore-prospecting direction in the area was suggested based on the extraction and integrated interpretation of remote sensing information of mineralization.The interpretation of remote sensing information of geological structures indicated that there is a large ring structure with diameter of about 2.5 ～ 3 kilometer in Jialong metallogenic area,and there are two small ring structures intersecting in the large ring structure.NE-trending structure is dominant in this area,secondly for NWW-EW trending structure,which all have excellent spatial relationship with the ring structure.And there is close relation between alteration information of remote sensing and the ring structure,in and around of which,specially the intersection part of the ring structure and linear structure,and linear structures inside the ring structure,the alteration information became stronger than other area.Of course the above sites just belong to the favorable prospecting prediction areas.
