Abstract

In geochemical studies, two basic parameters, mean grade and variance, are used to characterize rocks and ores. It is easy to show that regardless of the nature of the spatial distribution of element content in the studied object at a sufficiently dense and uniform sampling network, the average content of the element is equal to the arithmetic mean ...
