Abstract

This paper is the first to document the presence of Triassic evaporites from the Anatolide-Toride carbonate platform by providing stratigraphic, structural, mineralogic, petrographic and isotopic analyses. We have performed isotopic analyses on selected gypsum samples with delta S-34 values vary between + 15. 1% and + 18.1 parts per thousand. and Sr-87/Sr-86 ranges between 0.707761 and 0.707772. The new isotopic data is very similar to Late Triassic gypsum of the Mediterranean belt, and therefore, the age of the gypsum-bearing formation is assigned as Late Triassic. We have carried out a detailed study in the area of Honaz Dagi, 20 km east of Denizli, SW Turkey and its close vicinity. Here, gypsum-bearing rocks are well exposed, allowing us to establish the stratigraphic and tectonic position of the sequence.
