摘要
研究区位于南祁连盆地,属于南祁连褶皱带,构造特征明显,其断裂、褶皱、凹陷发育,以往的地质勘探较少。由于其复杂的地质特征和高原环境,人们至今未对其进行详细勘察。本文通过对研究区所获取的岩心进行采样,分析了泥岩、砂岩等47件标本的电参数,29件标本的密度参数,53件标本的放射性参数及磁化率参数,32件标本的纵波波速等物性特征。其间通过分析岩石的物性特征差异,归纳总结了岩矿石的电性、密度、放射性、磁化率及纵波波速等物性特征。
The study area is located in the South Qilian Basin and belongs to the South Qilian Fold Belt,the structur⁃al features are obvious,and its fractures,folds and depressions are developed,and there have been few geological ex⁃plorations in the past.Due to its complex geological features and plateau environment,people have not carried out de⁃tailed surveys to date.In this paper,by sampling the cores obtained in the study area,The physical parameters of 47 specimens such as mudstone and sandstone,density parameters of 29 specimens,radioactivity and magnetic suscepti⁃bility parameters of 53 specimens,and longitudinal wave velocity of 32 specimens were analyzed.During the analysis of the differences in physical properties of rocks,the electrical properties,density,radioactivity,magnetic susceptibil⁃ity and longitudinal wave velocity of rock ores were summarized.
