Abstract. Folds associated with inverted extensional faults are important exploration targets in many basins across our planet. A common cause for failure to trap hydrocarbons inversion structures is crestal breaching or erosion of top seal. The likelihood increases as the intensity grows. Inversion also decreases amount overburden, which can adversely affect maturation source rocks within unde...

The detailed mechanism of electronic bipolar resistance switching (BRS) in the Pt/TiO(2)/Pt structure was examined. The conduction mechanism analysis showed that the trap-free and trap-mediated space-charge-limited conduction (SCLC) governs the low and high resistance state of BRS, respectively. The SCLC was confirmed by fitting the current-voltage characteristics of low and high resistance sta...

The stratigraphic framework of the uppermost Jurassic Lower Cretaceous interval of the Gulf area is revised using both historical and recently acquired paleontological (ammonites, calpionellids, foraminifers, 'calcareous' algae), sedimentological and sequential information. The Kahmah regional Series ranging in age from Late Tithonian to Gargasian (= middle Aptian) times is subdivided into regi...

During the Miocene prominent oxygen isotope events (Mi-events) reflect major changes in glaciation, while carbonate isotope maxima (CM-events) reflect changes in organic carbon burial, particularly during the Monterey carbon isotope excursion. However, despite their importance to the global climate history they have never been recorded in shallow marine carbonate successions. The Decontra secti...

The fossil record of dinosaurs from the Early Cretaceous of Eastern North America is scant, especially since a few stratigraphic units from the east are fossiliferous. Among these stratigraphic units, the Arundel Clay of the eastern seaboard has produced the best-characterized dinosaur faunas known from the Early Cretaceous of Eastern North America. The diverse dinosaur fauna of the Arundel Cla...

Marine stable isotope records provide the basis for much of our understanding of past climates. During the past four decades of research, the exploitation of climatic information contained in marine stable isotopes led to the generation of a global network of marine stable isotope records. In particular, oxygen isotope records have been used to estimate past water temperatures, ice sheet sizes,...

during the period of april to november 1994, an investigation was carried out on fauna of phlebotominac in ilam province, west of iran. about 12000 sandflies were caught by sticky trap, light trap and aspirator from different ecological regions and were identified. these sandflies consist of 22 species (11 species from the genus phlebotomus: ph. paptasi, ph.sergenti, ph.alexandri, ph.rnajor, ph...

In the past 10 years an abundance of new models aimed at finding a better or even the ultimate solution for the structure and evolution of the Mediterranean Tethys have been published. These models are based on new geophysical (mainly paleomagnetic) results, refined stratigraphic and facies data, and sometimes even on detailed geochemical analyses. They were constructed with the help of paleaog...

It is suggested that homotaxial biostratigraphic units are an unsuitable basis for the definition of a New Zealand Tertiary geological time scale. Three other possible ways of setting up a time scale are discussed, and it is concluded that stratigraphic marker pegs offer the best basis for a rigorously defined time scale. In order to avoid the disadvantages of a hierarchical system of naming it...

Botrychiopsis has been considered an important floristic element of Westphalian/Artinskian associations of the Paraná Basin. The occurrence of Botrychiopsis in roof-shales of the Rio Bonito Formation in Southern Paraná Basin (Quitéria area), supported by the identification of Botrychiopsis valida, enlarges the genus biochron. Consequently, the stratigraphic hierarchy for Botrychiopsis plantiana...
