REMOTE SENSING GEOLOGICAL INTERPRETATION AND ORE-CONTROLLING REGULARITY OF LINE-RING STRUCTURES IN BEIJING-TIANJIN-HEBEI REGION

Linear and ring structures are closely related to the formation of mineral resources. With obtained Landsat 8 OLI remote sensing images, the geological interpretation for linear and ring structures is carried out on the basis of geological background and mineral data collection in Beijing-Tianjin-Hebei region. The ArcGIS is used to analyze the buffer zones of linear and ring structures and their intersections in the study area. According to the image features of linear and ring structures and their relationship with distribution of ore occurrences, the ore-controlling regularities and models of line-ring structure are summarized, which can provide a basis for remote sensing prospecting and delineation of metallogenic prospects.
