摘要
将连山关地区航空放射性伽玛能谱数据经过通用计算机进行插值、数据压缩和灰阶转换后, 输入到数字图像处理系统进行增强、分解、叠合、复合、分类、提取等处理,并与地质、遥感等 数据拟合,形成各类专题图像。在此基础上进行综合地质分析研究,新发现一些地质构造及矿化 现象,并提出一些新看法,不仅对认识连山关地区铀成矿的地质构造环境和进一步找矿有重要意 义,而且会促进伽玛能谱数据的二次开发和多源地学信息数字图像综合处理技术的深入发展。
This paper focuses on how to process the airborne comma data of GR- 800D high sensitivity spectrometer and apply them into uranium exploration. In order to get a matrix of array data which is similar to tile MSS image intensity .of pixels, the interpolation method, data compression and gray scale conversion method are employed. Then the data are input into image processing system in which a variety of manipulations such as enhancement, abstraction, integration and decomposition are utilized. Also multi-geological data such as geophysical and geochemical data are integrated with remote sensing data. Based on the comprehensive, analyses of the processed data, some new geological structure and mineralization have been found and some flew understandings have been obtained. All these not only are of geological importance for understanding of the tectonic setting of uranium mineralization and further explorating in Lianshanguan, but also promote the second development of airborne gamma data and the advancement of digital image integration technique of multi-geological data.
