stratigraphy, paleontology and paleoecology characteristics of stars valley deposits in qeshm island
stars valley is one of the tourism areas in the qeshm island and is located at the southwest of qeshm city, south eastern corner of the island. sediments forming this unique landscape are not completely lithified and is composed of marl and marly limestone which is formed by erosional and weathering processes. deposits of stars valley contain diverse assemblages of echinoids, bivalves, gastropo...
rainfall is recognized as one of the main triggering factors of landslides. researchers have long attempted to determine the amount of precipitation required to trigger slope failures. one of the landslide zones in iran is chaharmahal & bakhtiari province where many landslides cause high casualties in recent decades. it is significant that most of these landslides occur after a rainy period...
Abstract The Schrattenkalk Formation represents a complete succession of Lower Cretaceous shallow-water carbonate platform series cropping out in the Alpstein massif north-eastern Switzerland. is traditionally divided into two sedimentary units, “Lower” and “Upper” Schrattenkalk, separated by more marly Rawil Member. habitually dated to late Barremian, while Member are early Aptian. New field o...
Groundwater is the main resource for irrigation and drinking supply in most parts of Syria, as Mediterranean countries, however this suffers from mismanagement. In study area (northeast Mt. Hermon), lack information makes water management extremely difficult. Assessing groundwater pollution risk essential issue resources management, especially regions where complex interaction between climate, ...
The hilly landscape of the Periadric area in Central Italy is characterized by mainly marly–clayey foredeep basin deposits (Plio–Pleistocene age). These lithotypes are generally considered aquicludes, if compared with regional limestone aquifers Apennines. However, a coarsening upward trend characterizes upper portion this stratigraphic sequence, arenaceous and even conglomerates on top. From g...
During many decades, the town of Moulay Yacoub underwent an important urban expansion to meet high demand on housing fuelled by tourism activities, which constitute backbone town’s economy. Unfortunately, majority buildings, both private and public, suffer from varying levels damage related lithological, climate, geomorphic settings area. In fact, is built a marly hill prone various types mass ...
The copper skarn deposit at Gowdal is located in northeast of Shivardagh batholithic body, north of Ahar, East-Azarbaidjan Province. The Shivardagh intrusive body is a part of the magmatic belt of the Alborz-Azarbaidjan-Lesser Caucasus which in turn is related to the magmatic arc of the Meso-Tethys Ocean. The skarn mineralization of copper, iron, and molybdenum (chalcopyrite, pyrite, molybdenit...
Abstract Our understanding of the stratigraphic expression astronomically driven climate-change cycles in Milankovitch frequency band has improved significantly recent decades. However, several aspects have been little studied to date, such as nature climatically regulated environmental processes that ultimately control cyclic sedimentation. Similarly, relatively is known about successions accu...
The well-known fossiliferous and lithologically variable Middle Devonian Shaly-Calcareous Skały Formation in the Łysogóry Region (northern part of Holy Cross Mountains, central Poland) was studied for first time terms elemental geochemistry, carbon isotope stratigraphy limestone microfacies. Three Lower to Givetian marly-limestone successions, exposed at Miłoszów, represent middle outer facies ...
Type Ia supernovae (SNIa) have been used as approximate standard candles to measure cosmological parameters such as the Hubble constant and the deceleration parameter. These measurements rely on empirical correlations between peak luminosities and other features that can be observed in the supernovae spectra and their light curves. Such correlations deserve further study since they have been es...
