摘要
随着我国国民经济和社会建设的持续高速发展,对矿产资源的需求越来越大,供需矛盾日益加剧。在地质工作程度较低的大兴安岭成矿区带寻找新的矿产资源基地,保证矿产资源的稳定供应,是维持国民经济可持续发展的重要途径之一。充分发挥遥感技术优势,快速勘查评价此地区的矿产资源,是一种十分有效的工作方法。
     本文在内蒙古东南部扎鲁特旗地区选取5个主要铜多金属成矿区作为研究区,利用ETM遥感数据,在充分分析区域成矿地质条件和矿产分布规律的基础上,采用多种遥感图像处理和信息提取技术,提取出了与矿化有关的遥感蚀变信息,以现代成矿理论为指导,进行综合成矿预测研究,取得了以下主要研究成果:
     1、根据ETM波段数据特征值的统计分析,采用多种遥感图像处理技术,获得了研究区基础地质—地貌图像;结合研究区已有的地质资料,通过遥感影像特征分析,建立了遥感地质解译标志,在野外地质调查的基础上,确定了地层、构造和岩体的位置界线,填编了遥感地质解译图,为进一步开展地质找矿工作提供了新的基础资料。
     2、在充分分析岩矿光谱特征和ETM波段性能的基础上,结合研究区已有的地质矿产资料,采用特征主成分分析方法,辅助波段比值、图像掩膜、密度分割等技术,建立了遥感蚀变信息提取模型,去除植被等干扰因素,提取出了与金属矿化有关的遥感蚀变信息。通过对重点地段遥感蚀变异常的野外查证与分析,深入了解了研究区遥感蚀变异常的空间分布特征及其与矿产的内在联系,新发现了多处褐铁矿化、硅化等蚀变地段,为综合成矿预测研究提供了有利依据。
     3、通过对已知矿床(点)的调查分析,认为研究区内的金属矿产主要集中分布于突泉—天山北东向成矿带和黄岗—甘珠尔庙—乌兰浩特北东向成矿带内,孟恩、布敦花和黄合吐等主要矿化集中区均受东西向断裂的控制,金属矿产分布总体呈现出北北东成带、东西成行且等间距展布的空间格局,矿床类型主要有矽卡岩型、脉状热液型及斑岩型,主攻矿种为铜、铅、锌、银、金等。
     4、以遥感地质解译、矿化蚀变信息提取和异常查证结果为基础,结合地质、物化探成果资料的全面分析,在现代成矿理论的指导下,分别建立了铜、铅、锌、铁和金等典型矿区的遥感找矿标志和找矿模式,依据不同的成矿地质背景、成矿环境和成矿条件,进行了研究区的遥感综合成矿预测,共圈定了19处成矿预测区,其中Ⅰ级预测区9处、Ⅱ级预测区6处、Ⅲ级预测区4处,为在研究区部署地质勘查工作提供了科学依据,指明了方向。
With the development of our natioanl economic and social construction, the more and more mineral resources will be needed, and the confict between supply and demand is becoming bigger and bigger. Looking for new mineral resource in the Daxingan mountain metallogenic of low degree of geological works to ensure the steady supply of mineral resources is an important way of maintaining the sustainable development of the national economic. Fully utilizing the advantage of remote sensing technique and rapid evaluating the exploration of mineral resources in this region is a very effective working method.
     This article selected five major copper metal mining areas as the study area in Zhalute county seated in south-eastern of Inner Mongolia. In this article, ETM multi-spectral remote sensing data was used. Based on the full analysis of regional ore-forming geological conditions and distribution of mineral resources, this article applied several remote sensing information extraction technologies to extract alteration information related to the mental mineralization. Under the direction of modern mineralization theory, it is conducted that the ore prospecting research. The major findings are as follows:
     1. Based on statistical analysis of the characteristics of the value of ETM images, this article used a variety of remote sensing image processing technology and got the geological - geomorphological image of the research area; combining the remote sensing image characteristic analysis with the geological minerals material known in this area, the remote sensing image interpretation keys was formed. Based on the field geological investigation, it identified the confines of stratum, structure and rock, filled the remote sensing geological interpretation map ,and it also offered new informations to develop geological exploration.
     2. On the basis of the full analysis of rock mineral spectrum characteristic and the ETM band performance, combined with the geological minerals material known in this area,the characteristic principal components analytic method, the ratio method, the image mask technology,the density separation method are used to bulid the remote sensing alteration information extraction model and to remove the interference information of vegetation,the altered information of relating to metal mineralized was separately extracted. Through the verification and analysis of the key location, we deeply understood the spatial distribution characteristics of remote sensing altered information and it internal relations with the mineral. Many newly discovered limonite and silicides are found; it provides a favorable basis for the ore prospecting research.
     3. Through the survey of the known mineral deposit, it is considered that metal mineral areas are mainly focus on Tuqan - North-East Tianshan metallogenic belt and Huanggang - Kanjur Temple - NE Wulanhaote metallogenic belt. The mineralize focus area of Mengen, Budunhua and Huanghetu were subject to East-West fault control. The study area showed that the spatial pattern of distribution of the overall North-North East into a zone and space travel East-West raw with equal distance. The mainly kinds of mineral deposit are skarn, Hydrothermal vein-type and Porphyry. The mainly mine are Cu, Sn, Zn, Ag, Au and so on.
     4. Based on the remote sensing geological interpretation, altered information extraction and the verification of the key location which combined with the geology and the analysis result of Geophysical-Geochemical,the remote sensing prospecting criteria and model of the diggings of Cu, Sn, Zn, Ag and Au are bulied under the direction of the modern mineralization theory. The research areas's mineralization prognostic were conducted according to the different geological setting, conditions and environment of ore-forming, a total of 19 forecast areas were delineaed , including 9 I level forecast area, 6 II level and 4 III level. It provided an important scientific basis for the deployment of geological exploration work and identicated its direction.
