摘　　要：山门银矿位于山门Ag-Au-Ni找矿远景区中南部.通过对典型矿床及远景区的ETM数据、ALOS图像处理及遥感地质特征解译,总结出山门银矿的形成与依兰-伊通断裂带附近的次级断裂关系密切,并受北东向区域性脆韧性变形构造及环形构造控制.根据这一特征,在远景区内圈出7个最小预测区,总结了各预测区遥感预测依据,为在该地区成矿预测及找寻该类型矿产提供遥感依据.The Shanmen silver deposit is located in the southern part of Shanmen Ag-Au-Ni prospecting area.With the ETM data,ALOS image processing and remote sensing interpretation of geological features of typical deposits and the prospecting area as well,it is concluded that the formation of the Shanmen silver deposit is closely associated with the second-order faults near the Yilan-Yitong fault zone,and controlled by the NE-trending regional brittle-ductile deformation and circular structures.Based on this result,seven minimum prediction areas are delineated.The remote sensing basis for the prediction is also summarized,which would hopefully provide a guide to the mineral prospecting by remote sensing in the area.
