摘要:
提要:勘查地球化学诞生于20世纪30年代初期,经历了80年的发展,已经成为一门重要的地球化学分支科学,为矿产勘查做出了巨大贡献。本文对勘查地球化学过去80年发展历程的标志性事件进行了回顾;对勘查地球化学基础理论研究进展和对矿产发现做出的贡献进行了概括总结;对近年勘查地球化学最为活跃的研究领域进行了简要介绍。在20世纪70年代以前勘查地球化学作为一门独立学科已经形成,它的标志性事件是经典教科书的出版、勘查地球化学专业设立、勘查地球化学杂志的创刊、国际勘查地球化学家协会成立和勘查地球化学学术会议定期召开。在基础理论研究方面体现在局部地球化学分散模型和区域分布模式的建立。一些国家大规模区域或国家地球化学调查或填图计划的实施,为全球3次批量矿床发现作出了巨大贡献。近些年勘查地球化学最为活跃的研究领域集中在:(1)在微观尺度上,从纳米水平和分子水平研究化学元素的分散和迁移机理,发展覆盖区找矿的地球化学技术;(2)在区域尺度上,继续开展区域地球化学调查或填图理论与技术研究,为成矿带地球化学评价和靶区圈定提供高质量数据和图件;(3)在全球尺度上,致力于全球地球化学基准建立,为了解全球化学元素分布背景、过去地球化学演化和预测未来全球化学变化提供定量评价标尺。

Abstract:
Abstract:Exploration geochemistry has made great achievements both in basic knowledge of dispersion and distribution of elements and applications in mineral exploration since it was born in the 1930s. The author has generalized its growing up landmarks, reviewed its theoretical studies and contributions to mineral discoveries in the past 80 years, and described most active research fields at present. The growing up progress can be seen from the landmarks such as publication of classic text books, teaching of exploration geochemistry in universities, issuing of journals of geochemical exploration, establishment of associations of exploration geochemists and initiation of international exploration geochemistry symposia. Theoretical studies have been based on dispersion and distribution patterns of elements and mechanisms which control the dispersion and distribution of the elements. Exploration geochemistry, particularly applied to regional geochemical surveys/mapping, has delineated numerous geochemical anomalies leading to mineral discoveries all over the world. At present, the most active research fields are focused on 1)nano-scale and molecular-level understanding of migration mechanism of elements from covered mineral deposits, 2) regional-scale geochemical mapping; 3) global-scale geochemical baselines.
