中国化探走向2000年

总结了80年代中国化探的成就与不足之处。目的是更好的对中国化探走向2000年进行战略部署。中国的区域化探全国扫面计划在80年代取得了重大成就。已覆盖了400万km²的面积,发现了600余新的矿化产地,其中158个已成为新的有工业价值的矿床。研制了适用于乾旱、半乾旱、高寒山区、卡斯特及黄土覆盖地区的野外工作方法。研制了高效率低检出限的多元素分析系统及质量监控方案。所有这一切使得中国在系统进行地球化学填图工作方面在全世界居于领先地位,并带动了中国化探的全面发展。主要的不足之处是从80年代后半叶起,研究工作在指导整个这项计划的作用逐渐削弱,而整个计划逐渐变成纯生产性的例行工作。地球化学填图将成为地学及勘查地球化学新前沿已为国际上许多杰出科学家所承认。中国在填图技术以及信息累积上所占有的优势将给中国勘查地球化学家在90年代提供激动人心的新机会。简略的提出了一些新的研究方向。

GEOCHEMICAL EXPLORATION IN CHINA TOWARD THEYEAR 2000

Achievements and shortcomings of geochemlcal exploration in China inthe 1980s are reviewed with aim to better strategic planning of geochemicalexploration research and development works toward the Year 2000.China's national geochemical mapping project （Regional Geochemistry-Reconnaissance RM Project） has been very successful in the 1980s. About4 million km² of China's territory have been covered by this project. Morethan 600 new mineral occurrences and 158 new economic mineral deposits havebeen discovered. Optimum sampling methods for arid, semi-arid, igh mou-ntains, karst and loess-covered terains have been developed. Effective multi-element analytical systems and data quality monitoring procedure have beenworked out. All these make China ahead of the world in systematic geochemi-cal mapping. The main shortcoming is that the research imputs have becomelesser and the project has changed more and more into purely routine opera-tions in the later half of 1980s.That geochemical mapping will be one of the most important researchfrontiers in geosciences and exploration geochemistry has been acknowledgedby many prominent earth scientists of the world. The preponderance intechnics developed and information accumulated in this field of study isproviding exciting opportunities for Chinese exploration geochemists in the1990s. Some important and promising research topics are briefly suggested.
