基于多源遥感影像的吉林敦化塔东铁矿断裂构造解译

Multi-source remote sensing image-based interpretation of faults in Tadong iron mining district,Dunhua,Jilin province

采用多源遥感数据对断裂构造信息进行提取,具有更高的准确度和可信度。文章对吉林省敦化市塔东铁矿区及周边区域采用ETM+、资源一号02C和高分一号3种遥感数据对断裂构造进行解译。在利用中低分辨率的ETM+遥感影像进行地质构造的宏观特征信息提取、解译基础上,利用高分辨率的高分一号遥感影像,读取影像反映出来的微观地质特征。通过野外实地踏勘,验证并修正解译的构造信息。研究工作共解译出5组不同方向的断裂或线性构造,提高了地质调查工作的准确率和可靠性。

Data of ETM+,Resource-02c,Gaofen-1 are combined to interpret the fault structures in Tadong iron mining district,Dunhua city,Jilin province.Macroscopic feature information of geological structure is extracted and interpreted from ETM+remote sensing images with medium and low resolution.Then the micro-features of geology were directly observed on high-resolution remote sensing images of Gaofen-1.Field check is conducted to verify and correct the interpreted structural information.Five groups of faults or linear structure in different dirctions were interpreted and proved improving the accuracy and reliability of geological survey.
