ABSTRACT

Ulukisla (Nigde/Turkey) evaporites that compose the study area are situated in Ulukisla
Basin at the east of Nigde, South of Central Anatolia. The aim of the study is to
investigate the geological, mineralogical and geochemical properties of the gypsum and
anhydrites in Ulukisla Evaporites and to determine usage area of the evaporites as an
industrial material. For this scope, 50 anhydrite and gypsum samples were collected
systematically from the Ulukisla evaporites in 900 m thick area. By XRD (X - Ray
Diffraction) investigations, the structure of minerals that forms the anhydrites and
gypsum, by geochemical analysis major oxides and trace elements percentages, by
polarizing microscope, binocular microscope and SEM their mineralogical properties
were determined.

Result of the geochemical analysis, samples are pure gypsum minerals including some
trace elements. Trace elements are Mg, Al, P, K,, Fe, Rb, and Sr. SEM studies show that
there is no different crystal structure in evaporites. Parallel to the surface of lamination
and perpendicular to the surface structure was examined. Polarizan microscope studies
show the mosaic (lumpy) and diamond mesh textured gypsum. In binocular microscopy
examination selenitic gypsum has transparent structure, and under approximately 1-2
mm thick layer of gypsum, there are needle-like objects can be seen easily.

According to the analysis results, gypsum in the region are good quality gypsum for the
plaster production.
