云南矿化集中域影像线环结构定位预测

金属矿床遥感影像特征与地学信息的相关性是矿床遥感地质方法研究矿化集中域矿床展布规律、开展成矿预测的基础。遥感图像中特定的、具一定地质意义的影像线-环结构,标志一定成矿地质构造单元的影像单元(赋矿影像-地质单元),与成矿有关的地质-构造-岩浆-矿化系统相对应的影像线-环构造系(赋矿影像线-环体制),构成赋矿遥感影像网络结构,具有影像特征和地质特征的双重性。影像网络结构的群集性、节律性、贯穿性、对应性;影像网络结构的综合性信息标志功能,可提供矿化集中域成矿地质环境、成矿地质条件、矿床时空展布信息,作为矿床定位预测的重要信息标志。

Prediction on the Location of Mineralization-Centralized Area in Yunnan Province with Line-annulus Structure

Geological remote sensing provides a method to study the distributing laws of metal deposit in mineralization-centralized area, through the combine between the image of remote sensing and geological information, and by which prediction on the location of deposit can be developed. The line-annulus structure with special geological information, indicates a special geological unit with mineralization, indicates a system of geology, structure, magma and mineralization, constitutes a network of remote sensing image, be provided with both of the characteristics of image and geology. The mass, rhythm, transfixion and corresponding of image network, provide a comprehensive information, indicate the geological circumstance and condition of mineralization, and the information of deposit's distributing, which are important signs to predict location of deposit.
