Extension and calc-alkaline volcanism of the submerged orogen of alpine age (OAA) initiated in Early Oligocene (~33/32 Ma) and reached the stage of oceanic opening in Early-Miocene (Burdigalian), Late-Miocene and Late-Pliocene. In the Burdigalian (~20-16 Ma) period of widespread volcanism of calcalkaline type on the margins of oceanic domain, seafloor spreading originated the deep basins of nor...

Three sections of Guri Member the Mishan Formation in Bandar Abbas area are investigated for foraminifera biozonation and lithostratigraphic correlation. The base conformably overlies Gachsaran (or Razak some sections), whereas top member is overlain by marls. Thirty-four foraminifer species identified prove age Burdigalian Gery Sheikh Anguran Burdigalian–Langhan range Bāz section. Two assembla...

A NEW GENUS AND SPECIES OF PYGMY GRASSHOPPER (ORTHOPTERA Tetrigidae) is described from Early Miocene (Burdigalian) Dominican amber. Electrotettix attenboroughi Heads & Thomas, gen. et sp. n. is assigned to the subfamily Cladonotinae based on the deeply forked frontal costa, but is remarkable for the presence of tegmina and hind wings, hitherto unknown in this subfamily.

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....

Within a 5.5 m thick succession of Upper Burdigalian (Karpatian) sediments in the North Alpine Foreland Basin (NAFB; Austria), dated to CNP-zone NN4, a highresolution section was logged continuously. One hundred samples were taken with a resolution of ∼ 10 mm (approximating ∼ 17 years) per layer and analyzed using an integrated multi-proxy approach. Earlier analyses of geochemistry and calcareo...

A new species of fossil bumble bee (Apinae: Bombini) is described and figured from Early Miocene (Burdigalian) deposits of the Most Basin at the Bílina Mine, Czech Republic. Bombus trophoniussp. n., is placed within the subgenus Cullumanobombus Vogt and distinguished from the several species groups therein. The species is apparently most similar to the Nearctic B. (Cullumanobombus) rufocinctus ...

The carbonate strata of the Burdigalian Guri Member are located in Dezful Embayment along northern Persian Gulf shore. Ichnofabric analysis and paleoecology described by investigating three outcrop sections. facies features show a very shallow marine environment with high oxidation content. contains remarkably well-preserved specimens Thalassinoides suevicus. It is mainly recorded as Y T forms ...

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...
