NEW DATA ON THE GEOLOGICAL STRUCTURE OF THE SYNNYR ULTRA-K INTRUSIVE FORMATION
https://doi.org/10.5800/GT-2022-13-4-0658
Abstract
The Synnyrsky massif is the largest intrusive containing ultra-potassium syenites, synnyrites, which are raw materials for the production of potash fertilizers and aluminum. An extensive complex of geological and geochemical studies has been carried out, including exploratory drilling, which was carried out on the massif for the first time. The data obtained made it possible to significantly change the idea of the structure of the massif, including a different look at the regularities of the placement of potash-alumina ores, significantly increasing the ore potential and the reliability of its assessment. The present study discusses the existence within the Synnyrsky complex of the third, previously undetected, large intrusive phase, which has its own geological and geochemical features.
Supporting agencies: The studies are performed as a part of the state assignment of the Ministry of Science and Higher Education of the Russian Federation to conduct research on theme 0284-2021-0008 "Geochemistry, petrology and ore content of intrusive and volcanic alkaline complexes and deposits of strategic metals, their mantle sources" and the project of Baikal Nedra Geo Ltd.
