THE FEATURES OF HIGHLY ELECTRICAL CONDUCTIVITY LAYER IN NORTH CHINA AND NORTHWEST CHINA REGIONS |
| |
| Abstract: | The magnetotelluric soundings reveal the existence of high conductivity layer in the middle crust and upper mantle in certain regions of North China and Northwest China. It has an important significance for studying the structures within crust and upper mantle, physical state of rocks, crustal seismicity and so on. This paper summarizes all the data of highly electrical conductivity layers in these regions and describes their distribution regularity and their conicidence with the tectonic charac |
