利用卫星遥感影像,结合1∶5万地质调查资料,通过野外调查验证,从砂石资源地质体光谱特征(色调)、影纹特征(影纹)、形态特征(地貌)、水系、植被等方面建立了山东省砂石资源遥感解译标志,采用目视解译和人工交互解译,对9类矿种赋矿层位岩性组进行解译,大致查明具有开发前景的含矿层位岩体或岩性组分布,通过开展野外查证与现场修正工作,完成60处重点调查区9类矿种遥感解译区块的数量合计965处,面积合计2 050.79 km2.为野外专项地质工作提供了技术支持,同时为砂石土类矿业权的区块设置提供了一种较为快速准确的方法,在矿产规划、矿产资源开发管理等各方面具有较好的应用前景.
By using satellite remote sensing images,combining with geological surveying data with the scale of 1:50000,through field investigation and verification,the remote sensing interpretation marks of sand-stone resources in Shandong province have been established from the aspects of spectral characteristics(hue),shadow characteristics(shadow),morphological characteristics(landform),water system and vegetation.The lithology groups of 9 types of ore-bearing horizons have been interpreted by using visual interpretation and manual interactive interpretation.The distribution of ore-bearing strata or lithological groups with development prospects has been roughly identified.Through field verification and on-site correction work,a total of 965 remote sensing interpretation blocks of 9 types of minerals in 60 key survey areas have been completed with a total area of 2050.79km2.It will provide technical support for specialized geological work in the field.It also will provide a relatively fast and accurate method for setting up blocks of sand,gravel and soil mining rights.It has good application prospects in planning,development and management of mineral resources.
