通过图像显示系统,实现了铀资源多种地学信息数字图像的综合处理。其内容包括资料的输入处理;资料的配准、插值处理以及多源地学信息的增强、分解、提取、分类、叠合、复合等处理。以65盆地为样区进行了试验性研究。利用图像的信息增强、叠合技术研究了试验区的地质构造环境;利用图像信息的分解、叠合技术分析了U、Th、K的分布格局及其地质意义;通过矿床找矿判据的复合、提取进行了找矿靶区的初选;采用信息的分类技术进行了65盆地地区铀资源的总体评价。通过上述计算机信息处理技术,对这个研究程度较高的老矿区,在某些重要地质问题上,取得了一些新认识,并经野外检验预测了6片成矿远景地段。在上述研究基础上,初步建立了铀资源多种地学信息数字图像综合技术系统。
Through the image display system, a comprehensive processing of a variety of geo-information digital images of uranium resources has been achieved. Its contents include data input and processing; data registration, interpolation and multi-source geo-information enhancement, decomposition, extraction, classification, overlapping, compounding and other processing. A pilot study of 65 basins was conducted. Using the image information enhancement and superimposition technique, the geological tectonic environment in the experimental area was studied. The distribution pattern of U, Th, K and its geological significance were analyzed by using the decomposition and superimposition of image information. By the combination of prospecting criteria , Extracted primary targets for the prospecting target area, and classified the uranium resources in 65 basins using the information classification technology. Through the above computer information processing technology, some new geological conditions have been obtained in the old mining area with higher degree of research, and six ore prospecting locations have been forecasted through field test. On the basis of the above research, we have preliminarily established a comprehensive digital image technology system for uranium resources and various geosciences.
