The authors first develop a simulating system-EGCLTH having application in geochemical mapping. It is a nonlinear data processing and graphic systen. Using EGCLTH system high den- sity geochemical measuring results can be achieved automatically from low density sampling data. For example, we have constructed the geochemical maps of China corresponding to a sampling density of 1 sample/6400 km2 from the data of 529 samples, nearly covering the whole land surface of China, rpovided by Xie Xuejin (1995). Global Sampling Committee, International geochemical Mapping Project is taking a lpan in which the world’s land surface will be covered with 5000-6000 smaples. EGCLTH system will make quickly it possible to construct an Asia and World geochemical Atlas from the data of these samples.

During the long evolution of petroleum formation,some aromatic components such as benzene, phenol and anthracene would migrate from the oil and gas reservoirs to the surface of the earth and form the so-called geochemical anomalies. Both chromatography and chemical element analysis are commonly applied to investigation of these anomalies. Since 1981, we have been working by method of ultraviolet absorption analysis in research of the geochemical anomalies and have obtained some results which may be beneficial to the fluorescence analysis of ground water. Ground water samples were collected
