龙门山构造带北段岩石物性研究
The physical properties study of the northern section of iongmenshan tectonic belt
摘要
Abstract
Before starting many geological work ,in order to carry out the work effectively and successfully ,we often need to understand the physical differences of rocks and minerals in study area ,including the electrical differences 、magnetic differ‐ences and density differences .The study of physical properties is not only the essential foundation of geophysical field work and geological interpretation ,but also reflects geological and weather conditions in which they are formed .This study find that the physical properties of the north section of Longmen mountain tectonic belt have big differences ,especially the resistivity 、mag‐netic susceptibility and density .Electrical method ,magnetic method ,and gravity method can be carried out in the study area . We find the characteristic of physical properties in study area .It can guide electrical method ,electromagnetic method ,gravity and magnetic exploration method .After acquisition physical data of rocks ,combing the geological characteristics of the study area and the results of statistical and correlation analysis to analyze the physical distributions of rocks and the main influencing factors of the study area .Choosing relevant profile and comparing with the result of Audio - frequency Magneto telluric ,find‐ing that the near - surface resistivity features have a good correspondence .It also certificates the accuracy of the AM T test re‐sults .It can provide better overview for geophysical survey and geological interpretation in the study area .关键词
