多源地学数据综合处理技术在金属矿产预测中的应用

以计算机图像分析技术为手段、采用概念模式资源评价方法, 对多源地学信息进行综合分析。 获取多种地质异常和综合信息, 建立各类矿产的找矿标志和概念模式, 发现找矿线索, 选择找矿 靶区, 再次评价老矿区和正在普查找矿的成矿地段, 以及寻找新的工作靶区。采用多元统计方法与教学图像处理相结合的新技术, 以特定的专题图像、图示表达物探、化 探、遥感和地质等多因素的统计特征及综合模型的结果, 再现出各成矿区的地质构造骨架、岩浆 岩形态产状、岩性地层、矿化异常以及与它们的相互关系和空间分布特点, 为分析特定地区的成 矿地质环境, 研究构造一岩浆活动特征, 揭示深部构造与成矿关系, 建立综合解译标志, 提取新 的综合性二次信息等提供了可靠的科学依据。

APPLICATION OF INTEGRATION PROCESSING TECHNIQUE FOR MULTISOURCE GEOSCIENTIFIC-DATA IN PREDICTING FOR METAL MINERAL DEPOSITS

The multisource geoscientific-data are comprehensively analysed by means of the computer image analysis technique and the resources evaluating method of concept pattern. We can obtain the varied geological anomalies and comp- rehensive information, establish the ore guides of prespecting and concept pattern for a variety of metal mineral deposits, find the clues of prespecting, select prespecting targets. and reevaluete the old ore-fields and minerogenetic areas being searched. We combine the two types of new technique of multi-variate statistic and digital image processing. the multi-factors statistic fealure and results of comprehensive model from the geophsical. geochemical. remote sensing and geological data, etc., are presented by the special thematic images and graphys. In every minerogenetic-areas. it is reappeared that the tectonic framework, shape and attitude of magmatic rock, lithological strata, mineralizing anomalies. and their inter-relationship and spatial distribution charactor. The reliable scientific basis is provided for analysing the minerogenetic geological environment of special areas, studying the feature of tectonic magmatic activity, revealing the relationship between the deep tectonics and the minerogenetic, establishing the guides of comprehensive interpreting and extracting the new comprehensive secondary information.
