我国西部特殊景观区化探方法研究进展

西部特殊景观区的化探方法研究一直是中国化探界的一个研究热点和难点.在岩石出露、水系发育地区可以沿用传统的水系沉积物化探方法,但在覆盖景观区,常规化探方法效果并不理想.目前,谢学锦和王学求所提出的深穿透地球化学方法,经过一系列的实验研究,证明其能在覆盖区达到快速有效地圈定战略靶区的作用,具有广泛的应用前景.要做好西部特殊景观区的化探工作,化探科研人员必需采取新方法、新思路,继续系统地开展化探方法技术研究,通过不懈的努力最终找到一套适合中国西部特殊景观区特别是覆盖区的行之有效的化探方法.

ADVANCES IN THE RESEARCH OF GEOCHEMICAL EXPLORATION METHODS IN SPECIAL LANDSCAPE AREAS OF WESTERN CHINA

The study of the geochemical exploration methods in special landscape areas of western China has been a hotspot and difficult research point in geochemical prospecting work. In rock-exposed and stream-developed areas we can still use the traditional geochemical stream sediment survey method, but in the covered landscape areas it is not proper to use the conventional methods. At present, with the performance of lots of experiments, it has been proved that the Deep-Penetrating Geochemical Prospecting Method introduced recently can define strategic targets speedily and effectively in the coverage area, thus having wide application prospect. To improve geochemical exploration in special landscape areas of western China, geochemical exploration researchers need to take new methods and new thoughts and systematically develop the research on geochemical methodology, thus finally formulizing a full set of effective geochemical methods suitable for special landscape areas, especially for coverage areas in western China.
