以找矿预测和成矿作用为目的的线性构造解译和研究已成为构造、遥感和成矿作用共同关注的热点。本文对IKONOS遥感影像的全色波段与多光谱波段进行Gram-schmidt方法融合,通过傅立叶变换和空间滤波,进行空间频谱变换以分离并突出各种频率成分,增强和提取了甲马矿区微线性线性构造信息。利用GIS技术统计分析线性构造的一般特征及其与矿床空间分布上的耦合关系,根据线性构造的规模和对甲马铜多金属矿床控制作用的意义不同,将其分为区域尺度一级控矿构造和二级控矿构造,从而指导甲马的外围及深部找矿勘查实践。

In ore prediction and mineralization process,linear structure interpretation and research have been common focuses among structure,remote sensing and prospecting for ore deposits.Fusion of multispectral and panchromatic images based on the Gram-schmidt method is carried out on IKONOS images,and spacial frequency spectrum transformation is used to separate and highlight the various frequency components through the Fourier transforming and spatial filtering,then the micro linear structure information of Jama mining area is enhanced and extracted.By using GIS to statistical analyse the general characteristics of linear structure and the relation between linear structure and deposit distribution,in light of the scale of linear structure and different meaning of linear structure in controlling Jama polymetallic deposit,the linear structure is divided into regional scale level ore-controlling structure and secondary ore-controlling structure,so as to guide the ore exploration practice in periphery and deep position of Jama.
