Abstract: Geophysical-geochemical technical method library is an integral part of China Geological Survey Technology Information. On the basis of comprehensive research, geophysical methods were summarized as gravity, magnetic, electrical, seismic, radiological and geothermal six classes, twenty-five kinds, geochemical methods were summarized as sediment, soil, rock, gas, water, biological and other seven classes, sixteen kinds, and each technology method was briefly introduced. After screened, 208 messages relating to geophysical-geochemical technical method, instruments and equipment, software and application examples were compiled and warehoused. On these bases, the contents of geophysical-geochemical technique method library were preliminarily enriched, and these provided a basic operation condition for the service platform of geophysical-geochemical method library
