Geological Remote Sensing for the Transverse Structures in Tianshan Area

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.
