Abstract: To understand the crust-mantle material density and velocity structure geological significance, the crust-mantle physical property parameters of data are intergrated based on the years of geological and geophysical comprehensive interpretation work. Generally speaking, along with the increased depth of the earth's crust, mantle and outer core density and velocity are positive correlation. From various perspectives (graphs, bar charts, forms, structural layer, rock mineral) of crust-mantle physical parameters change rule, geological and geophysical comprehensive interpretation key basic data of matter in the interior of the earth are provided in the research.
