Lithologically; the Asmari Formation consists of limestone; dolomitic limestone; dolomite; argillacious limestone; some anhydrite (Kalhur Member) and sandstone (Ahvaz Member). this study based on the analysis of core samples from four subsurface section (well Mn-68; Mn-281; Mn-292 and Mn-312) in the Marun oieldfield in Dezful Embayment subzone in order to infer their provienance; tectonic setting of the Ahvaz sandstone member. petrographic data reveal that the Ahwaz sandstone comprise 97.5 % quartz; 1.6% feldspar and 0.9% rock fragments and all samples are classified as quartz arenit. the provinance and tectonic setting of the Ahvaz sandstone have been assessed using integrated petrographic and geochemical studies. petrographic analysis reveals that mono and poly crystalline quartz grains from metamorphic and igneous rocks of a craton interior setting were the dominant sources. chemically; major and trace element concentrations in the rocks of the Ahvaz sandstone indicate deposition in a passive continental margin setting. as indicated by the CIW index (chemical index of weathering) of the Ahvaz sandstone (average value of 82) their source area underwent intensive recycling but moderate to high degree of chemical weathering. the petrography and geochemistry results are consistent with a tropical; humid climate and low relief high land},
