Abstract: It is China's special continental Crusl that decides the unique of petroleunl in China. Because of small area of lhe conlinentaI crust. being compressed o11 all sides and volcanic movenent and new tectonic activities, there exist abundaurt dcep materials from the carlh in domestic crude oils. Particularly, the elements from the core and mantle sn1ch as various metal ones should be rnorc paid atlention to. To focus on theoreti-cal and technical studies in peLrolcuni metallurgical industry will greatly inerease the eronomic values of the crude (ils, thus allowing the short-age of domnestic mineral resources to Le flleld up and China's petrochemical industry to be further developed rontinually.

Key words: crust, mantle, metal element, resource proteclion, metallurgy
