摘要
论证了中国丰度及地壳表层物质成分研究的必要性和重要性 ,利用区域地球化学勘查所提供的高精度分析数据 ,经严格统计计算 ,发表新疆地区及其一级构造单元表层岩石、岩屑、水系沉积物的 39种元素背景平均值。
This paper has expounded and proved the necessity and importance of the investigation into element abundances and composition of the crustal surficial materials and, based on strict statistical analysis and calculation of the high-precision data provided by regional geochemical exploration, presented average background values of 39 sorts of elements in rocks, debris and stream sediments in Xinjiang region and its first-order tectonic units.
