Abstract: Microelements of crude oil and isotope compositions (Pb, Sr and Nd) show petroleum is a product from deep mantle source. The facts that there is coexisting relationship among petroleum, metal and diamond deposits, and hydrocarbon and bitumen occur in the inclusion and kimberlite indicate that petroleum even took part in the hydrothermalism. That crude oil and natural gas lie in petroliferous basins is related to the basinal basement crust's insulation which allows the preservation of volatile compositions in asthenosphere of upper mantle bulge and the full geochemical actions. The basinal basement crust is the more stable hard block, its rotation occurred under the global strike-slip process may lead to forming variety of deep faults and traps under the compresso-shear and tenso-shear stresses besides uplifting of mantle. The deep faulting in late periods of tectonic movements becomes the channels for oil-gas migration, when the oil-gas reservoirs will be formed as long as there is any trap. The theory of deep source origin is based on strict experiments. The petroleum thermodynamic equilibrium calculation demonstrates that oils can be originated in mantle's asthenosphere. The different depths of hydrocarbon composition occurrences provide rational explanations for zonations of oil and gas.
