A comprehensive remote sensing-structure analysis of the complicated structural district in orogenic belt——with the Tonghuashan-Yushugou area in south Tian mountain as example

Based on the research of structure of Tonghushan-Yushugou area, this paper sets forth the predominance of inter-research of remote sensing and structure. To anatomy the supracrustal composition and structure of orogenic belt with the regional linear structures and their partitioned block and schistous geological masses as the macro-frame(in corresponding to structure units and structure segments) and with the rock masses, structure-rock assemblages, line-featured and belt-featured structures as well as penetrative and non-penetrative foliation (primary stratum and transposition layering) and folds as the texture and structure elements is the main contents of remote sensing analysis. By means of the integration of field survey and image processing, the supracrustal composition and structure of different type in orogenic belt are decomposed, the relationship of these structure are analyzed.
