Abstract This paper makes a review and summarization of the second generationregional geochemical prospecting work carried out by Mnistry of Geologyand Mineral Resources all over China in the past 12 years with special refere-nce to its ore-prospecting achievements and economic benefits with whichpeople are concerned. For the purpose of better evaluating the state of utili-zatidn of the available regional geochemical data by geological bureaus ofvarious provinces and autonomous regions affiliated to MGMR, the applica-tion of regional geochemical anomaly inspection method as well as the qualityof this work and the further reconnaissance and detailed survey for ore occur-rences discovered by regional geochemical prospecting, this paper, based onthe statistios of various sorts of data provided by all the bureaus, advancesthree evaluation parameters, i. e. sites/10,000 km2, ore-detection percentageand thorough investigation percentage of all deposits. On such a basis, a commentis made on every item of work concerning regional geochemical prospectingconducted by geological bureaus of various provinces and autonomous regions.As for future work, it is pointed out that (1) the most urgent matter at pre-sent is to make full use of the availab1e regional geochemical data; (2) ano-maly appraisal and anomaly inspection, especially the working method andquality of anomaly examination, remain a weak link in the geochemical workof every geological bureau.
