| 摘 要： | 通过对辽宁省建平县北部地区遥感影像处理，提取OH-、Fe3+矿化蚀变信息，对照1：20万敖汉旗幅地质矿产图，结合成矿理论，经GPS野外指引实地异常信息检查，在该区发现两处矿化点.此工作方法找矿效果明显，为今后加快地质找矿工作提供了一条可参考的、行之有效的途径.

| Abstract: | With processing for the remote sensing image of the northern area in Jianping County, Liaoning Province, the mineralization and alteration information of OH-and Fe3+ is extracted. Referring to the geologic and mineral map in a scale of 1∶ 200000 in the area, under the metallogenic theory, with field investigation and correctness of the alteration information by GPS, two spots of altering anomaly are finally found. The result of exploration is remarkable. This method provides an effective means for further mineral investigation. |
