遥感综合信息在宁芜地区找矿预测中的应用
|
摘要
为了研究宁芜北段火山岩盆的矿产资源潜力及空间分布,本文以Landsat8中分辨率遥感数据及Pleiades1高分辨率遥感数据为数据源,综合运用目视解译法和多种遥感图像增强技术,结合区域成矿地质背景,对研究区进行了遥感影像解译,提取了与预测矿种密切相关的线、环、色、带、块遥感五要素。通过分析遥感五要素矿产地质特征与矿产点分布关系表明,研究区内的铁铜硫金矿床及星罗棋布的矿点大部分位于构造岩浆成矿亚带中,受区内北东向、东西向、北西向及其它断裂纵横交叉形成的断裂网格及火山机构控制,大多分布在数条断裂带交汇位置,另有一些分布在断裂带与环形构造的交汇处附近。基于主要的矿点受区内断裂网格及火山机构控制,遥感图像的综合地质信息特征与找矿目标紧密相联,说明了基于遥感图像的综合信息可以作为找矿预测的标志。
This work aimed to investigate the potential and spatial distribution of mineral resources in the northern Nanjing-Wuhu volcanic basin using remote sensing data. The data employed included Landsat 8 medium-resolution data and Pleiades 1 high-resolution data. Using the visual interpretation method and several remote sensing image enhancement technologies,we interpreted the remote sensing images to extract lines,rings,colors,belts and block elements based on regional geological setting. In addition,this work analyzed the relationship between the mine geological characteristics of the five remote sensing interpretation elements and the distribution of mineral-producing areas. The results show that the iron,copper,sulfur,gold deposits and scattered mines in the study area are mostly located in tectonomagmatic belts,which are controlled by the network of northeast-trending,east-west-trending faults,and northwest-trending faults as well as volcano structures. Most deposits lie at fault intersections,while others are at conjunctions of faults and circular structures. The geological information derived from remote sensing data is closely related to prospecting targets,and thus can be used as clues in prospecting prediction.
