美国地质调查所受原子能委员会的委托,进行了科罗拉多高原砂岩型铀矿床中微量元素分布的研究工作。研究的主要目的是为了提供一些基础资料,以便用来对新矿床进行地球化学勘探工作。本文描述了一种基本统计方法——它与沉积岩石学中所应用者相类似。下述的原则是,频率分布曲线符合于或接近于正态分布的形状。
The United States Geological Survey Commission commissioned by the Commission on the Colorado plateau sandstone-type uranium deposits in the distribution of trace elements. The main purpose of the study was to provide some basic information for geochemical exploration of the new deposit. This article describes a basic statistical method - it is similar to that used in sedimentary petrology. The following principle is that the frequency distribution curve is at or near the normal distribution.
