DIFFERENCES OF MAGNETIC SUSCEPTIBILITY'S INTERPRETATION MECHANISM BETWEEN CAOXIAN LOESS AND XIAOLIANGSHAN LATERITE SEDIMENTARY SECTION

Because of fastly,conveniently,and nondestructivly,magnetic susceptibility,it had been widely used as a research method to indicate paleoenvironment,and played an important role in analyzing the moving,transforming of magnetic minerals in environment system and then got a series of research achievement.In fact,the influence factors of magnetic susceptibility were various,so when analyzing paleoenvironment by use of magnetic susceptibility data,it should be necessary to prudently use and combine with other experiment data,especially pay more attention to the magnetic susceptibility's response to different sedimentary types.In order to analyse the instruction meaning of paleoenvironment by useing of magnetic susceptibility,two different sedimentary types has been chosen in this paper,which are loess and laterite,we can know the instruction meaning of magnetic susceptibility of different sedimentary types,and load a foundation to correctly analyse magnetic susceptibility.
