塔里木盆地遥感区域地质研究

Remote Sensing Study on Regional Geology in Tarim Basin, China

本文着重阐述将塔里木盆地（地块）划分出“内、中、外三环体（带）”的构造新格局；提出该区存在着巨大的“环式弧形构造系统”及其相应的“环式弧形成矿带”与“环式弧形地质环境带”的新论点与新概念，揭示该区矿产资源的成矿、控矿规律，建立行之有效“多位一体”的遥感地质找矿模式；发现环绕塔里木盆地油气、钾盐、煤、铀、金属、建材及宝玉石等５个环状成矿带和罗布泊特大型钾盐矿产基地；以及塔克拉玛干大沙漠区内４大富水区，并提出塔里木地壳具“稳定之中不稳定，不稳定中有稳定”等新的认识。

The paper presents the results of study on mineral resources and geological structure in Tarim region, imcluding Tarim basin and its surrounding areas (up to 1 million km2), by using '35' techniques and supplemental research methods such as geology, geophysics and geochemistry. The results show the special kind of tectonic framework constructed by the internal, middle and outside circular zones. Based on the fact above and mineral interpretation, the new structure types, so-called 'arc-looped structure' and 'arc-looped geological environmental belted system ' which control the regional mineral distribution . Are put forward. A comprehensive prospecting model, which is called the integrated analysis on multiple key factors of geology, has beed established. The five circular belts of mineralization zones which favorable are to oil and gas, potash salt, uranium and coal, metal, nonferrous such as construction materials, gem and jade, are distinguished, and the super-large scale potash salt prospects in Luobubo region and four rich-water areas in the Taklamakan Desert are discovered. In addition, the new points of characteristics of Tarim block movement and structural system are proposed as 'stable area in unstable background and unstable area in stable background'.
