NEW DATA ON THE GEOLOGICAL STRUCTURE OF THE SYNNYR ULTRA-K INTRUSIVE FORMATION

The Synnyrsky massif is the largest intrusive containing ultra-potassium syenites, synnyrites, which are raw materials for production of potash fertilizers and aluminum. An extensive complex geological geochemical studies has been carried out, including exploratory drilling, was out on first time. data obtained made it possible to significantly change idea structure massif, a different look at regularities placement potash-alumina ores, increasing ore potential reliability its assessment. present study discusses existence within third, previously undetected, large phase, own features.
