了解和确定元素的背景含量,不但可以确定、对比、分析和解释元素的地球化学异常,进而发现矿体,而且对于地层对比、了解和解决成矿物质来源等基础地质问题,也有很大的意义.但是,元素背景值的计算手续繁杂,花费时间颇多.为适应区域化探中大量资料整理工作的需要,我们经过对计算方法的研究和对比,提出下列较为简便的方法. 一般认为,一定地质过程形成的地质体,其金属含量分布,服从某种统计分布规律——正态分布或对数正态分布.因此,在统计和处理数据
Understanding and determining the background content of elements not only confirms, compares, analyzes and interprets the elemental geochemical anomalies, and then finds the ore bodies, but also has great significance in understanding and resolving basic geological problems such as the source of metallogenic materials for formation stratigraphy However, the procedures for calculating the background value of elements are complicated and time-consuming. In order to meet the needs of a large amount of data collation in regional geochemical exploration, we propose the following simple and convenient methods after comparing and calculating methods: Generally, Geological process of the formation of geological bodies, the metal content distribution, subject to some statistical distribution - normal distribution or lognormal distribution.Therefore, in the statistical and data processing
