京津冀地区线环构造遥感地质解译与控矿规律分析

线性构造和环形构造与矿产的生成有着密切的内在联系. 在京津冀地区地质背景与矿产资料搜集的基础上，获取京津冀地区Landsat 8 OLI遥感影像，继而对遥感影像上的线性和环形构造进行遥感地质解译；并借助于ArcGIS平台对研究区内的线性构造和环形构造及其交汇部位进行缓冲区分析，根据线性、环形构造的影像特征及其与矿点的产出关系，总结出线-环形构造的控矿规律及控矿模式，为以后遥感找矿、圈定成矿远景区提供依据.

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.
