Quantitative Statistics of Linear Structure Based on Remote Sensing Image and Metallogenic Prediction for Lingqiu

选用Landsat7 ETM+图像做数据源,进行预处理、741波段合成加强图像构造信息,以此进行线性构造解译。利用定量统计方法绘制出线性体强度图、密度图。依据研究区线性体异常高值区、地球化学异常和已知矿床(点)分布资料归纳分析,圈定出3个级别的7个成矿前景区。

The Landsat7 ETM ＋ image is used as the data source, and the 741 band synthesis is used to enhance the image structure information, and the linear structure interpretation is carried out. Using the quantitative statistical method to draw a linear body intensity map, density map. Based on the analysis of the data of high-level linear anomalies, geochemical anomalies and known deposits （points） in the study area, seven metallogenic foreground areas are delineated.
