â â â  abstract â  in this study, 129 samples of the qom formation in kaltakeh, south east mahneshan, were investigated. the thickness of qom formation in the examined section is 565m and comprises of limestone, sandy limestone, marl, shale and argillaceous limestone . at this locality, the qom sediments disconformably overlies the lower red formation and underlies the upper red formation. amon...

The subject of the study is real and probable connections Aquitanian (and in particular Poitevin) poetry High Middle Ages with traditions early Medieval Celtic Welsh) literature. A narrower topic research was influence Welsh poems form Englyns on samples Guillaume IX's poetry, primarily forms englyn milwr penfyr. An additional metric features these Englyns. At same time, a broader possible orig...

Abstract The precise ages of Cenozoic basaltic rocks from 20 localities (24 samples) in south-western Poland were studied by means the 40 Ar/ 39 Ar isotope method. Three phases volcanic activity identified this area. older, Ruphelian phase took place 31–29 Ma ago and younger, Aquitanian occurred 22–21 ago. Significantly younger (4.8–4.6 Ma: Zanclean phase) obtained for basalts cropping out vici...

a total 7 species and 13 genera of marine gastropod assemblages are reported for the first time from the varehh zard section (asmari formation), north of pole dokhtar, lorestan basin. the section under study, the asmari formation, lies between the shahbazam formation at the base and gachsaran formation at the top. according to the distribution of index foraminifera, the asmari formation is earl...

The Cenozoic sedimentary cover of the Malaguide Complex (Internal Betic Cordillera, Spain), in Almería and Málaga areas, consists a suite successions from continental shallow-marine to deep-marine environments. Structural stratigraphic relations, petrological geochemical signatures reveal evolution (CMC) pre-orogenic (Palocene-Eocene) syn-orogenic (Oligocene-Early Miocene) stages. Sandstones de...

The Pyrenean orogen extended eastward, across the present-day Gulf of Lion margin. late or post-orogenic dismantling this segment, contemporaneous with ongoing shortening in Spanish Pyrénées, is still debated. Understanding transition between two geodynamic events requires to document precise timing succession tectonic processes involved. We investigate superposition rifting structures over thr...

Abstract Background The earliest Miocene (Aquitanian) represents a crucial time interval in the evolution of European squamates (i.e., lizards and snakes), witnessing high diversity taxa, including an array extinct forms but also representatives extant genera. We here conduct taxonomical survey along with histological/microanatomical approach on new squamate remains from Saint-Gérand-le-Puy, Fr...

In this study, four well-exposed outcrops of the Asmari Fm in the southeastern part of the Izeh Zone of the Zagros Mountains were measured and sampled. In this region, the Asmari Fm is Oligocene to Early Miocene in age as determined by large benthic foraminifera. Based on depositional geometries, biogenic contents and lateral and vertical variations of facies, three depositional models are prop...
