The present paper makes a systematic description on advances made by Chinese Academy of Geoexploration in such aspects of exploration technology as aerogeophysical prospecting, surface geophsical exploration, borehole geophysical prospecting, geochemical prospecting and remote-sensing geology.

Based on geological; geophysical and geochemical studies of the Yindongpo gold deposit; the authors established its prospecting criteria and ore - search model and; furthermore; made prognostic appraisal of geochemical anomalies in the ore dePOSit and ore zone as well as outside the ore zone. The utilization of the model to ore prospecting has improved the theory of geophysical and geochemical prospecting and raised research level of the ore dePOSit; thus yielding obvious geological and ore - prospecting effects. The present paper has given a detailed description of the results obtained in the research.

By utilizing surface geochemical data; one may effectively delineate geochemical anomalies and determine the range of vertical migration of hydrocarbon. Nevertheless; this merely meets the basic requirements for oil and gas exploration and is hence unsatisfactory. Through an analysis of vertical geochemical data and surface geochemical free hydrocarbon data; the present paper has made a preliminary discussion on the appliccation of geochemical kinetic indices to the determination of preservation conditions and buried depth of oil and gas accumulations.

Aimed at remedying the defects in quality inspection of cement - concrete highway; as well as in routine test methods currently used; the present paper has recounted the basic principles of adopting combined Rayleigh method; ultrasonic method and audio - frequency resonance method to test strength of road surface and roadbed as well as thickness of roadbed; and analysed some construction examples.

Geological radar is a modern high and new technology whose principle lies in utilization of propagation regularity of high - frequency eletromagnetic wave in underground media to conduct exploration and inspection. The present paper has made a preliminary discussion on the role played by geological radar at various stages of highway construction; with emphasis given to basic interpretation theory on non - destructive inspection of highway quality. Some application examples are also given.

High - resistance carbonate rocks that form karst merely show weak absorption of electromagnetic wave; basides; the specific layered deposition environment of carbonate rocks has caused fairly obvious anisotropic phenomena of rocks in carbonate rock areas. The existence of air - earth interface and the distinct interface caused by the obvious difference in electrical properties between media on both sides of the karst cave also lead to intense reflection and scattering of electromagnetic wave. The present paper made a study and analysis of the specific electromagnetic wave propagation phenomena in carbonate areas and; on such a basis; reached some conclusions.

Geophysical exploration work in the Yangbajing geothermal field might be divided into two stages.Employing the direct current method as the main method with the help of ground gravity and magnetic survey; the first stage aimed at delineating spatial limits of the thermal reservoir. The second stage was designed to meet the demand of deep thermal reservoir exploration and adopted suh methods as magnetotelluric sounding; frequency electromagnetic sounding; microseismogram sounding and ground noise survey in combination with gravity; magnetic and electric sounding data as well as geochemical and geological data. Such an integrated study yielded some' new achievements: the heat source of foe thermal field is further proved to be a localized magma chamber at the depth of more than 10km; the deep thermal reservoir is mainly located in the north of the thermal field and occurs in the shatter fissure zone at the depth of some 1000 - 3000m with the temperature evidenced by borehole data to be in excess of 300℃; the shallow thermal reservoir in the southern district of the thermal field is a secondary reservoir: the thermal fluid came mainly from the depth of the northern district; and when percolating southeastward; the thermal fluid was mixed with large quantities of cool groundwater; thus reducing the temperature but increasing the flow rate.

With the invention of proton magnetometers in 1960' s; magnetic exploration has become one of the main geophysical methods for exploring paleorelict. Meanwhile; the development of paleomagnetism has rendered magnetic stratigraphy very important in determining ages of paleorelict and fossils of ancient mankind. With the deepening of the research into magnetic characteristics of Quaternary sediments; a new way has also been opened up for environmnetal archaeology.Through practice and investigation; the author holds that; based on magnetic characteristics of the paleorelict itself and the strata it lies in; one may combine space; time and other aspects of environmental archaeology into unified archeological magnetics.With full and accurate data and examples; this paper has recounted its application effect as well as its working methods and techniques.
