New method of sampling by section types
Abstract
The proposed sampling method is based on a regular relationship between the structure of ore deposits in terms of thickness and the content of valuable mineral. The main object of the study was a deposit where the largest ore deposits are genetically and spatially associated with a primary well stratified rock complex. The main reason for the formation of stratified complex of rocks and ore deposits is crystallization differentiation, which apparently consisted in the following: a) movement of crystallizing magmatic melt; b) gravity; c) large accumulation of elements giving volatile compounds; d) increasing viscosity of crystallizing melt; e) non-uniform (consecutive from top to bottom) cooling of the intrusive body; f) two periods of melt crystallization: first - slow crystallization of mainly leucocratic minerals, second - faster crystallization of all other minerals of magmatic origin.
