中亚天山地区横向构造的航天遥感分析

Geological Remote Sensing for the Transverse Structures in Tianshan Area

运用中小比例尺航天图象。对中亚天山地区的横向构造进行研究，探讨深部构造信息的地表遥感特征及深部不均一性与地表不均一性的关系，并分析了天山地区大－超大型金、铜矿床的遥感地质背景。

According to the appearance on which nonuniformity of surface on the earth reflect deep structural nonuniformity, the paper studies the transverse structures, acrossing the Tianshan orogen, by morphostructural analysis based on NOAA AVHRR and LANDSAT MSS images. Formed in Variscan orogeny and due to multiperiodic activities, they appear to have diffuse belt and neotectonic feature, con sisting of series if tensional fractures and faults. Interpretation on image and geophysical survey suggest that they have deep seating and probably extend to lower-crust. More important, intersecting area of transverse structure and strike ones usually indicate the position of large metal deposit. Therefore, remote sensing survey of transverse structure is significance for prospecting metal deposits.
