造山带复杂结构构造区遥感-构造综合解析——以南天山东段铜花山—榆树沟地区解剖为例

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

通过对铜花山—榆树沟地区的解析研究,阐述了造山带复杂结构构造区遥感解析与构造解析交叉互动的优势。遥感解析以区域线状构造及由它划分的块状、片状地质体为宏观骨架(对应于构造解析划分的构造单元、构造均匀区段),以地质体中的岩体、构造岩石组合,线状、带状构造,透入性、非透入性面状(原始层理、新生面理)和褶皱等构造作为解析的结构构造要素,以造山带表壳组成和结构构造解析研究为主要内容。采用野外实测构造要素与遥感图像处理技术相结合,分解造山带不同层次、不同构造单元的物质组成和结构构造,达到解析造山带内各级各类构造及其内部构造要素之间的相互关系。

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.
