中国区域化探全国扫面计划卅年

The Implementation of the Regional Geochemistry-National Reconnaissance Program(RGNR) in China in the Past Thirty Years

区域化探全国扫面计划是一项科学研究研究与大规模调查密切结合的大科学计划。在20世纪70年代为计划的提出进行了许多预研究。1978年项目得到国家地质总局的批准。批准后正式展开之前进行了五年的技术准备。包括拟定工作方法规范、举办培训班、研制多元素多方法分析系统、制备水系沉积物土壤及岩石标准样,拟定分析质量监控方案及对各种特殊景观地区野外工作方法进行研究。这项计划至今已进行了30年,覆盖了全国700余万平方公里的面积。根据这项计划提供的地球化学异常的线索找到了数百个新矿床,特别是金矿。所取得的海量数据还对基础地质研究、环境、生态及农业的研究提供新的依据。并为国内外地球化学填图的思路与方法技术作出了极大贡献,使中国的地球化学填图走在了世界的最前列。

Regional Geochemistry-National Reconnaissance Program（RGNR） was a big science program incorporating scientific research with extensive surveying.Feasibility studies were carried out in the 1970s.The program was approved by the National Bureau of Geology in 1978.Before the full implementation of the program,a five-year project for technical preparation was carried out,which included the preparation of sampling protocol,the orientation of field surveys,the development of multi-elements,the multi-method analytical schemes,the preparation and certification of standard reference materials,and many courses for training working staff members,All these measures were aimed at overcoming the deficiencies commonly met in existing geochemical mapping programs in the world,such as the incomparability of elements mapped,the insufficiency of trace and subtrace element information and the incomparability of data.The program has been carried out in the past 30 years covering more than seven million square kilometers of China＇s territory.Hundreds of new mineral discoveries,especially gold discoveries were obtained.The immense amount of data obtained is also useful for geological,environmental ecological and agricultural studies.
