CLASSIFICATION AND CRITERIA FOR FORECASTING OF BOLSHOI ALTAY GOLD DEPOSITS

Abstract

The result of this researches is developing of regional and local criteria of gold deposits. These were also studied their age position; their connection with different geological formations. Zaisan collision zone has length more than 1000 km (NW-SE), and it width is about 20-40 km). It was formed as a result of collision displacement and coupling of lithosphere plates. Some of the most commercially valuable gold deposits of East Kazakhstan are located in several geochronological levels of the Devonian volcano-sedimentary stratigraphic succession. Flank gold ore belt is traced to Russia on the NW and China on the SE.
