In this paper, different applications of stereographic projections are utilized for the structural analysis Ranikot anticline. Structural data anticline from Southern Kirthar Fold Belt Pakistan is used to construct diagrams such as beta-diagrams, pi-diagrams and contour diagrams. These visualize inter-limb angle, plunge trend fold axis, dip strike axial surface, symmetry, vergence principle str...
Subsurface migration and accumulation of oil gas have interested researchers for a long time, but these processes may occur over very geological periods are difficult to observe directly, so experimental simulations warranted. In this study, an method was developed model hydrocarbon in the subsurface structure. Oil simulated sandbox model, industrial CT scanning used both internal geometry path...
As one of the predominant diagenetic products in clastic rocks, calcite cements are typical fingerprints cement-forming fluids and key controls on reservoir quality. The Puig-reig anticline, south-eastern Pyrenees (Spain), exposes excellent outcrops conglomerates, sandstones claystones, which were deposited from a proximal to medial fluvial system underwent folding, fracturing cementation. This...
In the Slovenian part of Gulf Trieste/Trst, submarine springs occur as funnel-shaped depressions in Holocene sandy-silt marine sediment that forms seafloor. These exhibit both elevated temperatures (up to 29.6 °C) and sulphur content. Based on their location, they are divided into three groups: Izola group (three springs), Bele skale (two Ronek (seven springs). Previous investigations linked th...
The Gurpi Formation with a thickness of 190 m at the Kouh-e sefid anticline is investigated with regard to the calcareous nannofossils. In this section, Gurpi Formation is mainly consists of shale, marls and argillaceous limestones. As a result of this study, 21 genera and 41 species of calcareous nannofossil have been recognized. Based on distribution of index species calcareous nannofossils...
In January 2010, we conducted a multichannel seismic (MCS) reflection survey in Sagami Bay. As a result of this study, the deformation of the Manazuru Knoll, which is located near the plate boundary, was obtained. The Manazuru Knoll was formed by an asymmetric anticline, and the knoll has a geometry that is bent in a shape similar to that of a crank. The anticlinal axis, which was confirmed by ...
The studied area covers two outcrops they are located within Sulaimaniya, northeastern of Iraq (Rania and Sargelu sections). Sections in village Unstable Shelf, High Folded Zone, including Surdash anticline, while Rania Sectionis city near Hanjira the Shaweri anticline. carbonates represent major microfacies constitute lime mudstone microfacies, wackestone Calcisphere-Posidonia submicrofacies, ...
Identifying the offshore thrust faults of Western Transverse Ranges that could produce large earthquakes and seafloor uplift is essential to assess potential geohazards for region. The in southern California are an E-W trending fold-and-thrust system extends west Ventura. Using a high-resolution seismic CHIRP dataset, we have identified Last Glacial Transgressive Surface (LGTS) two Holocene sei...
planktonic foraminifera are useful in determining the relative age of the upper cretaceous strata. based on distribution of planktonic foraminifera in kuh-e siah section (212 m thickness), eight biozones have been recognized including dicarinella concavata interval zone (earliest santonian), dicarinella asymetrica total range zone (santonian to earliest campanian), globotruncanita elevata parti...
