The study area is located in the southern parts of Tuzgolu basin namely closed Konya basin, which is one of the largest inner/closed basin of Neogene age in the Central Anatolia (Turkey). The basin was mostly filled with the Late Cretaceous-Quaternary aged different types of minerals. The basin, in deep, starts red colored clastic sediments which are formed from thick red clastic unit was deposited in shallow-deep-shallow marine environments. This study was primarily focused on the textural properties of halite mineral in the Miocene units. The textural properties of the halite mineral have been investigated mainly for detection of environmental conditions and origin of halites as primary and secondary halites. Remnant of chevrons structures are most common primary texture preserved in ancient halite deposits. Upward-growing chevrons determined in the halite minerals show that these textures contain rich fluid inclusions and have cloudy or milky appearance. Halite minerals are interlayered with carbonate, sulfate and clay minerals in the studied core samples. The halite layers are generally observed in thick of mm-dm, salt deposits in the dm-m in size precipitated when condition are suitable that huge thickness of shoal water evaporite can accumulate in very short time frames. The thin laminates of halite indicate the fluid chemistry causing the precipitation and changed in a short time interval of the environment condition. The presence of hoper-textures in halite minerals indicated that the first precipitated on the shallow hyper saline brine pools and when they were undisturbed by wind and waves. The secondary marks were commonly observed in the drillings as the nodular structure anhydrite and mosaic texture of halite. The ratios of Cl/Br and Na/Br in the studied halite samples have very high values that are in relation to dissolution and mixing.
