This study presents calcareous nannofossils biostratigraphy of the Campanian‒Danian interval at the Gurpi Formation in the southwest of Ilam Province, in the Zagros Basin. The studied sequence of the Gurpi Formation mainly consists of marly shale and limestones. The thickness of Gurpi Formation was measured as approximately 230 m. Forty-five species belonging to twenty-eight genera were recorde...

It is very important to identify the source of sediment yield in a drainage basin for any practical soil conservation program. Clay minerals in litological units, can be used as an indicator for prediction of soil erosion. Marl and marly-limestone of Neogen red beds, Hezardarreh Formation and Quaternery alluvium, are exposed in the Lateshure watershed. 21 sampels from surface soils of diff...

In this paper, we present a RC-in RC-out model order reduction method which takes RC circuits and accurate reduced models which can be realized using passive RC elements. The reduced models are accurate up to 2nd order moment and hence are more accurate than the first order moment matching based algorithm [3], [4], [ 5 ] . The runtime and reduction ratios of our method are not dependent on the ...

The current research studies the depositional setting of Jeribe Formation in south Mosul area northern Iraq, which is tectonically located Low Folded Zone characterized by deposition limestone and marly during Middle Miocene. Petrography has provided a diversity fauna such as benthonic foraminifera (Miliolid, Peneroplis sp., Dendritina sp. Borelis melo curdica) addition to Red Algae Mollusca. c...

Abstract Upper Miocene sedimentary deposits of Sierra de las Cabras in the Prebetic Ranges (Jumilla, Región Murcia, Spain) yield a exceptional fossil site diverse vertebrate ichnofauna, including mammals and birds. This paper presents detailed study those ichnites that which correspond to mammals. The footprints are located stratigraphic surfaces found thin marly limestone succession can be ass...

Shallow earth translational slides and earth flows, affecting colluvial soils derived by the weathering of the clayey bedrock, are a recurrent problem causing damage to buildings and roads in many areas of Apennines. The susceptibility assessment, e.g. slope stability models, requires the preliminary characterization of these superficial covers (lithology, geotechnical and hydraulic parameters)...

Meyers, P.A., 1993. Origin of the Plio-Pleistocene Vrica laminites: Organic geochemical evidence. Mar. Geol., 115: 117-127. Organic geochemical properties of samples from lower Pleistocene laminite Layer H at Vrica, Calabria, have been examined for evidence of the origin of these dark-colored sediments. The laminite samples are geochemically distinct from the surrounding gray marly clays. They ...
