Influence of Paleotectonics on the Structure and Mineral Composition of Potash Salts of the Upper Jurassic Formation of Central Asian Basin (Example of Tubegatan Deposit)

Abstract

Investigations of salt-bearing bed Nizhniy-2 of the Tubegatan field were conducted. The structural, textural features and mineral composition of the rock were determined that allowed to draw conclusions about the mechanisms and conditions of formation and diagenesis alteration of sylvinite and salt rock. The description of rocks, their typization along with clarification of the results by X-ray fluorescence and X-ray analysis were made. Analysis of paleotectonic environments, their division into different levels, and the assessment of impact of processes at each level on the structure and composition of potash rocks of the Upper Jurassic formation were described.
