| 摘 要： | 本文回顾和总结了地矿部12年来在全国范围内开展第二代区域化探工作所取得的找矿成果和经济效益等人们关心的问题.为了更好地评价地矿部各省、区局对目前已取得的区域化探资料的利用和发掘的程度、区域化探异常检查方法运用和工作质量以及对区域化探发现的矿产地所作的进一步普、详查工作,文章根据各局历年报部的各类工作数据的统计提出了单位面积内发现矿产地数(处/万km2)、见矿率(%)以及矿床查明率(%)等三个评价参数.在此基础上对各省、区局的区域化探中的各项工作进行了评论.对今后工作提出了:①当务之急是充分地全面地利用区域化探资料;②异常评价和异常查证仍是我部各局工作中的薄弱环节,特别是异常检查的工作方法和工作质量问题.

| 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. |
