Carst marble on Tyrnyauz deposit

The karst of marbles is considered as the least studied type of karst. Here we have pinpointed the karst area of the ore field of the Tyrnyauz deposit. Lithological and petrographic characteristics of the skarned marbles of Tyrnyauz are given, their chemical activity is determined. Tectonogenic fissure-karst drainage system of the deposit is analyzed. The main factors of karst formation have been determined and the development of the karst marbles of the Tyrnyauz ore field at various depths is predicte

Вiochemical impact of the Tyrnyauz field development on the Baksan river

The influence of the Tyrnyauz tungsten-mofybdenum plant on the water ecosystem of the Baksan River is investigated. The anomalies cased by mining activities in groundwater and surface waters, in suspended matter and in bottom sediments in long sections of the river valley are revealed. The relationship between the protein in bottom sediments and the concentrations of some heavy metals is determined and explaine
