甘肃省祁连山西段地球化学分区及其特征
Geochemical divisions of Yanchiwan area in western Qijian Mountain of Gansu Provinceand their characteristics
摘要
Abstract
The geochemical data of stream sediments contain significant geological and geochemical information. In this study,R factor analysis method was applied to 1:250 000 stream sediments data from Western Qilian Mountain. Five geochemical zones were recog-nized and their geological implications were discussed according to element association.The geochemical zones correspond to the tecton-ic units,and therefore these results can provide abundant geochemical implications for basic geology research,prediction of prospective areas and further division of Grade IV ore-forming belts.关键词
