The Beyşehir–Hoyran–Hadim Nappes crop out over 700 km from NW to SE. Above a regionally autochthonous Tauride carbonate platform the Beyşehir–Hoyran Nappes begin with a thrust sheet (c. 400 m) of mainly redeposited carbonates, quartzose sandstones and mudstones of Mid–Late Triassic age, interpreted as a proximal slope–base-of-slope succession. Above is a thrust sheet (c. 1 km) of Middle–Upper T...
We analyzed the tectonics and stratigraphy of Southern Great Tarakan Basin to determine its tectonic evolution during Mesozoic-Cenozoic Eras, basin geometry, potential hydrocarbon using integrated surface subsurface data. can be divided into three sub-basins, Berau, Muara, South Tarakan. They comprise deposits Jurassic Quaternary age, which assigned five mega sequences based on their lithologic...
The Diptera (true flies) is one of the most species-abundant orders of Insecta, and it is also among the most important flower-visiting insects. Dipteran fossils are abundant in the Mesozoic, especially in the Late Jurassic and Early Cretaceous. Here, we review the fossil record and early evolution of some Mesozoic lower brachyceran flies together with new records in Burmese amber, including Ta...
Until recently it was thought that all the erratic flints found at Stone Age sites in upper part of Odra Valley were considered as silicites from Baltic Sea. Their age is associated with Cretaceous, more precisely Maastrichtian or Palaeogene. However, turns out among these rocks, there are also different and origin. They first outcrops sands gravels around Opole-Groszowice, SW Poland. So far, h...
lurestan province is petroliferous area. the reserved oil are in ilam and sarvak (cretaceous ) and kangan ( lower triassic ) and dalan (permian) formations. the lurestan area had high exploration activity but contribution of source rocks in hydrocarbon accumulations isn’t clear. in this paper essential elements and process of hydrocarbon accumulation are introduced. candidate source rocks ar...
The Pycnodontiformes is a monophyletic group of predominantly Mesozoic fishes with mostly deep and laterally compressed bodies (Nursall 1996, 1999; Kriwet 2001a; Poyato-Ariza & Wenz 2002). They are highly specialised with regard to their prey, which is expressed in their durophageous dentition with rounded teeth arranged in more or less defined rows forming dental plates on the unpaired vomer i...
West Carpathian Mesozoic paleogeographic development indicates the effect of a left lateral shift of the Alpine- Carpathian microcontinent along the European shelf since the Early Jurassic. The evolution during Late Triassic/Early Jurassic was controlled by convergence along the border of the Meliata Ocean and by contemporaneous divergence along the Middle Atlantic/Penninic rift. During Mid-Cre...
In the present study, the sediments of the Gurpi Formation in the Jafarabad section located in the southeast of Ilam were examined from the point of view of calcareous calcareous nannofossils. The sediments of the upper part of Gurpi Formation with a thickness of about 42 m are composed of limy marl sediments. In this study, 34 species belonging to 22 genera from the group of calcareous nannopl...
