区域化探异常的地球化学勘查评价方法技术进展综述

区域地球化学异常筛选与评价之地球化学勘查方法技术一直是矿产勘查技术领域的一个热点问题。章回顾了近十几年来区域地球化学异常筛选的方法与思路以及评价异常的勘查地球化学方法的一些进展，并根据不同的覆盖条件和勘查地球化学技术应用条件，把它们分为厚覆盖区勘查地球化学方法技术、基岩区勘查地球化学技术和生物地球化学勘查技术加以评述，最后提出多种地学信息综合集成，尤其是信息科学技术，如地理信息系统、卫星定位系统和遥感技术等互相协作较准确的筛选异常，多学科结合的立体勘查地球化学方法是区域地球化学异常评价以预测隐伏矿床的主要趋势。

RESEARCH ADVANCES OF GEOCHEMICAL SURVEY METHODS AND TECHNOLOGIES OF REGIONAL GEOCHEMICAL ABNORMITIES

Geochemical survey methods and technologies of regional geochemical abnormities are always hot spots in economic geology exploration field. This paper reviewed and summarized research advances of geochemical survey methods and technologies of regional geochemical abnormities in recent ten years. According to different covering condition and technological application constrains, the geochemical survey methods and technologies can be divided into thick coating area geochemical survey methods and technology and bedrock area bio-geochemical survey methods and technologies. Finally, this paper put forward that kinds of geosciences information integration, especially, IT science, such as GIS/GPS and RS, to choice correct geochemical abnormities, and appraise that will be the main trends of research on prediction concealed mineral deposits.
