甘肃地球化学景观特征及区域地球化学方法技术评价

Landscape geochemistry features and evaluation for working method and technique of regional geochemical prospecting in Gansu Province

在总结甘肃省地质矿产局20年来区域地球化学工作方法的基础上,系统地分析了甘肃省的地质、地形、地貌及气候特征,将甘肃省划分为6个不同的景观地球化学分区。通过统计过去区域化探的工作方法,分析现有数据,总结近年来的找矿效果,认为在甘肃省的区域化探工作中,除甘肃东南部工作方法正确,找矿效果突出外,其他各景观区1:20万水系沉积物测量的工作方法技术不同程度地存在问题,有待进一步研究。

The paper analyzed geology and topography, as well as climate in Gansu Province in detail and divided Gansu into 6 geochemical landscapes on the basis of summarizing working methods of region geochemistry in 20 years in Gansu Bureau of Geological and Mineral.Through making statistic to working methods of region geochemistry past and analyzing data in existence and summarizing effect of looking for mine approximately, we think working methods of region geochemistry of the 5 geochemical landscapes have more or less errors except southeast Gansu Province, which is to be studied further.
