天山北坡乌鲁木齐至沙湾地区富硒土壤地球化学特征及成因探讨
A discussion on the geochemical features and origin of selenium-rich soil on the northern slope of the Tianshan Mountains from Urumqi to Shawan County
摘要
Abstract
Based on the multi⁃purpose regional geochemical survey, the authors discovered a large area of selenium⁃rich soils on the north slope of the Tianshan Mountains in Xinjiang from Urumqi to Shawan County. The selenium content is relatively high, and a variety of fertile elements are rich. The study shows that the selenium is mostly distributed in the surface soil and exhibits the positive correlation with the or⁃ganic content. It is indicated that the selenium originates in parent soil materials while the enrichment state of selenium depends on the super⁃gene geochemical circumstance of local fluvio⁃lacustrine deposits.关键词
