应用国际和国内实验室标准样,采用高灵敏度(0.2毫克/吨)高精度(±10％)的原子吸收分析方法,对西伯利亚表生带岩石和矿石、金矿床上覆的疏松沉积物和土壤、以及无矿区的金的分布规律进行了研究。研究确认,水云母、高岭土和红土型区域性风化壳,系由含金丰度值分别为4.5、4.1、和4.4毫克/吨的岩石风化而成。外来沉积物的区域背景值约为2.7毫克/吨,土壤的区域背景值在1.2～10.6毫克/吨之间。山地土壤,尤其是形成于正残积初始地貌条件下的土壤,通常含金量较高;形成于新残积初始地貌条件
Application of international and national laboratory standards, the use of high-sensitivity (0.2 mg / t) high-precision (± 10%) atomic absorption spectrometry analysis of Siberia epikarst rock and ore, gold deposits overlying loose sediments and soil , As well as the distribution of gold in non-mining areas were studied. The study confirms that weathered mica, kaolin and lateritic weathering crusts were weathered from rocks with gold abundances of 4.5, 4.1, and 4.4 mg / t, respectively. The background value of alien sediments is about 2.7 mg / t and the background value of soil is between 1.2 and 10.6 mg / t. Mountainous soils, especially those formed under the conditions of initial deformable initial geomorphology, usually have a higher gold content;
