Abstract: Deep materials of the earth tend to be brought by volcanic activities to crustal derm. A bivariate structural basin with sedimentary rock and volcanic rock has not only low geothermal and biogenic organic materials from the crustal derm,but also high geothermal and abiogenic materials from deep earth, which include gaseous materials such as CO, CO2, CH4, C2H6, C3H8, H2, He, Ar, etc., and liquid materials like hydrothermal juvenile water and various elements carried by water. Therefore, in a depositional basin where volcanic event took place, different natural gas resources composed of hydrocarbon gas and non-hydrocarbon gas should be existed, including biogenetic oil-gas resources, multi-element associated resources carried by water and/or oil as well as geothermal resources carried by water. In other words, crude and formation water existed in bivariate structural basin are not only of resource value by themselves,but also of more valuable associated resources of multiple elements; and they belong to minerals of deposits which will be as major resources in new-type industries such as oil metallurgical industry and subsurface water metallurgical industry in this new century.

Key words: volcanic activity, basin, liquid, gas, oil and gas resource
