The geology of the Darien province of eastern Panama is presented through a new geologic map and detailed biostratigraphic and paleobathymetric analysis of its Upper Cretaceous to upper Miocene sediments. The sequence of events inferred from the stratigraphie record includes the collision of the Panama arc (the southwestern margin of the Caribbean plate) and South American continent. Three tect...

Architecture of slopeand basin-floor-fan systems in growth-faulted subbasins along the south Texas Gulf Coast developed as a result of interplay between synsedimentary tectonics and sedimentation during third-order sea-level lowstands. These subbasins, or intraslope basins, have not been adequately explored for their slope and basin-floor-fan potential, as have the intraslope basins in salt-dom...

The mild compressional structures of Cenozoic age on the passive margins bordering Norway, the UK, the Faroes and Ireland have been the subject of much discussion in the literature. Nevertheless, their origin remains enigmatic. Candidate mechanisms must be able to explain the generation of sufficient stress to cause deformation, the episodic nature of the structures and why they developed where...

at the boundary between jurassic and cretaceous, because of late kimmerian movements, the sea ragressed from many areas of north and cantral iran, and many continental areas rose, which included a number of differentiated basins. the boundary between jurassic and cretaceous in these parts of iran is usually marked by a big diastem or by red, clastic and evaporitic sediments. the whole or part o...

The apatite fission track (FT) analysis of Jurassic sandstones from the Beipiao basin in the eastern China indicates a large variation in FT age peaks. The sandstone of the Beipiao Formation has two peak ages at 178.8 and 40.0 Ma, while the sandstone of the Tuchengzi Formation has three age peaks at 152.0, 77.5 and 32.5 Ma. This implies that the provenance of the Beipiao basin in the early Jura...

I sincerely thank my supervisor Prof. Dr. Wladyslaw (Wlady) Altermann and Dr. Michaela Frei. They do not only adviced me on academic issues, but also on my life in Munich. I thank Wlady for accepting this thesis, for respecting my cultural background and for his tolerance towards my ideas and behaviours. He was always encouraging me, which give me confidence to progress in my research work. Mic...

this study aims to identify favorable oil–gas reservoir facies in the chishan group of the wubao fault zone (gaoyou sag, subei basin, china) using the methods of outcrops and cores observation, granularity analysis, scanning electron microscope, log data, etc. the results suggest that the chishan group in the studied area mainly develops desert sedimentary system, and contains five kinds of fac...

  Introduction Identification of the climate changes is important for understanding the paleoenvironmental characteristics. Sedimentary evidence of the closed basins can be one of the most important methods for identifying the climatic periods and changes in the sedimentary environments. Gavkhouni Playa, as the lowland of the ZayandehRud River catchment area is located in an inter-mountainous...

The formation and deformation history of back-arc basins play a critical role in understanding the tectonics plate interactions. Furthermore, opening extensional during overall convergence between Africa Europe is fundamental process tectonic evolution Mediterranean adjacent areas. In this frame, Miocene western Pannonian Basin Central its connection to inherited Cretaceous structures Eastern A...
