F. González-Lodeiro (Y) 7 F. Aldaya 7 J. Galindo-Zaldívar A. Jabaloy Departamento de Geodinámica, Universidad de Granada, E-18071 Granada, Spain E-mail: jgalindo6goliat.ugr.es Abstract In the internal zones of the Betic cordilleras, extensional structures have developed from the Upper Oligocene to the present day; they are contemporaneous with compressional structures (folds and thrusts) in the...
asmari formation was deposited in the foreland zagros basin (southwest iran). in this research, biostratigraphy related to the asmari formation in north of khorram abad, robat namaki section, is discussed. in the studied stratigraphic section, the asmari formation overlies the shahbazan formation and underlies gachsaran formation and consists of cream to gray medium to thick limestone and marl....
This work introduces one of the first palynostatigraphic study conducted on formations from Eocene and overlying lowermost Miocene successions (Cunga Quifangondo formations) exposed in Onshore Kwanza Basin, Angola. To improve Cunga age, new biostratigraphic correlations palaeoenvironmental interpretations based qualitative quantitative analyses organic walled dinoflagellate cysts sedimentary ro...
Opening of the Alboran Sea-THE Alboran Sea contains two basins deeper than 1,000 m separated by a ridge which we shall cal1 the Alboran marginal fracture (Fig. 1). Seismic reflexion studies and data from the Joides drill site 121, situated exactly on the northern limit of the western basin, show that the deepest sedimentary layers, lying on the substratum, are older than upper Burdigalian (14 m...
The Cenozoic Malaguide Basin from Sierra Espuña (Murcia, S Spain): An Example of Geological Heritage
The Cenozoic Malaguide Basin from Sierra Espuña (Internal Betic Zone, S Spain) due to the quality of outcropping, areal representation, and continuity in sedimentation can be considered a key-basin. In last 30 years, large number studies with very different methodological approaches have been done area. Models indicate an evolution passive margin wedge-top basin Late Cretaceous Early Miocene. S...
One hundred and forty-four published successions of shallow-water carbonates, deposited between the Palaeocene Miocene, from Levant to Himalayas, have been re-analysed using a standardised approach investigate distribution carbonate facies carbonate-producing organisms. Large benthic foraminifera were found be volumetrically most important group producers during whole period, with peak in abund...
