GEOLOGY AND PROSPECTS OF THE SHU-ILE BELT GRANITOIDS AS BUILDING MATERIALS (SOUTH KAZAKHSTAN)

Abstract

Granitoids are very developed and widespread geological formations on the territory of Kazakhstan. Many mineral deposits are associated with them, in addition, they themselves are useful minerals, like building materials. The Shu-Ile tectonic belt in Kazakhstan is a large region of the Paleozoic granitoid massif. Many deposits of gold, non-ferrous metals and rare earth elements are associated with them. One of them is the Jeltau leucogranites complex, with which most of the facing stone objects are associated. In the region, due to the increased mechanical strength of leucogranites, along with deluvial rubble material, coarse-grained eluvium and outcrops of bedrocks are widely developed. One of the most significant factors affecting the quality of the mined stone is the fracturing of the rocks, which determines the possibility of obtaining blocks, taking into account the consumer demand of the customer. Therefore, during the exploration of the Jeltau deposit, special attention was paid to the study of the actual disturbance of rocks at bedrock outcrops, including those in the immediate surroundings of the exploited block, in wells and an experimental quarry. In general, granites have stable physical and mechanical properties over the entire area of the site, uniform petrographic and chemical composition. According to the geological conditions of occurrence and morphology of the mineral body, the deposit is simple. The deposit is characterized by sustained quality of raw materials and simple structure.
