The type section of the Middle and Upper Jurassic Chaman Bid Formation is in the western Koppeh Dagh Basin (Northeast Iran). It is unusually thick and contains a rather rich ammonite fauna, ranging from Bathonian to Tithonian. The ammonites described here come from a 134-m-thick interval in the upper part of member (D) in the middle part of the formation, consisting of an alternation of grey li...

The Fatha Formation, formerly known as the Lower Fars was deposited in a shallow basin, southern Iraq during Middle Miocene. By using description of cores, we found large heterogeneity lithology; contains mixing limestones, mudstone, marl, marly limestone, sandstone, and gypsum, or anhydrite. In this study, Formation divided into three main units according to lithofacies, namely, marl-anhydrite...

the qom formation in southwest kashan in sanandaj-sirjan fore arc basin has a thickness of 190 meters and is composed of medium to thick and massive bedded limestone, marly limestone, sandy limestone, marl and coglomerates. study of these deposits led to recognition of nine microfacies related to a carbonate platform. the high presence of perforate foraminifera in most of the recognized microfa...

calcareous nannofossil assemblages of the boundary paleocene-eocene deposits (pabdeh formation) of the zagros, dezful embayment-mansouri oilfield have been studied in detail. it consists of shale and grey marlstone with inter layers of calcareous argillites and marly claystone. we present a study focused on changes in calcareous nannofossils of the pabdeh formation during the paleocene/eocene b...

Abstract. At the interface between lithosphere and atmosphere, critical zone records complex interactions erosion, climate, geologic substrate, life can be directly monitored. Long data (30 consecutive years for sediment yields) collected in sparsely vegetated, steep, small marly badland catchments of Draix–Bléone Critical Zone Observatory (CZO), SE France, allow analyzing potential climatic co...
