摘要
Abstract
In the Altay high latitude glacial till covering area, an analysis of rock magnetic data shows that magnetic properties of rocks are different from each other conspicuously. The magnetic anomaly identification marks have been established preliminarily. The mag⁃netic field can be divided into three districts:Ⅰ⁃1 high stability zone corresponding to biotite granite, andⅠ⁃2 highly jumping magnet⁃ic field zone reflecting the distribution of Silurian hypometamorphic rocks; Ⅱ medium stability magnetic field zone corresponding to two⁃mica granite; Ⅲ low magnetic field zone representing the reflection of Sinian⁃Cambrian weak to non⁃magnetic epimetamorphic rocks. Eight NW⁃and NE⁃trending concealed faulted structures were determined through deduction. The results achieved by the author provide geophysical basis for the construction of the structural framework of this area. The ground high⁃precision magnetic survey is ef⁃fective in supplementary geological mapping of the glacial till covering area and plays a guiding role in practical geological mapping.关键词
