Abstract

This study covers the investigations related to the glauberite-halite minerals detected in Neogene deposits of the Ereğ- li-Bor Basin in the Central Anatolia. The basin consists of Paleozoic basement rocks, the unconformably overlying Paleocene-Eocene-Oligocene marine sedimentary and volcano-sedimentary rocks, and the Lower Miocene-Pliocene lake deposits at the top which unconformably overlie all underlying layers. In the study, core drillings related to the determination of geological characteristics and investigation of the mineral potential of buried salt deposits were carried out in the Ereğli-Bor basin. As a result of drillings carried out, glauberite-bloedite, halite and bituminous shale horizons, which possess significant thickness and grade values, were cut for the first time in the Konya-Ereğli-Bor basin. Glauberite minerals were observed in three different structures as; 1- the Glauberite Mineral intercalated with High Graded, Bedded Clays, 2- the Glauberite Mineral with Disseminated Rosette Type in Low Graded Clays and 3- the Prismatic High Graded Glauberite Mineral intercalated with Halites. Bloedite minerals are mostly observed with halite. It was detected that the economical evaporitic formations in the Konya-Ereğli-Bor Basin had occurred within the Upper Miocene-Pliocene Katrandedetepe formation which represents the playa-lake environment.
