The importance of the landscapes for development recreation and ecotourism is significant but very little studied. Usually, scientists use spatial units to map assess ecosystem services CORINE land cover or similar classifications. Traditional multi-level landscape classifications, well-known developed in XXth century Bulgaria, Russia, other Eastern Central European countries, could give valuab...
The Northparkes district, central New South Wales, hosts several economic Cu–Au deposits associated with discrete, thin, porphyry intrusive complexes emplaced in the Late Ordovician during formation of Macquarie Arc. recently discovered Two-Thirty Cu–Au–(Mo) prospect is a mineralised magmatic–hydrothermal breccia complex that hosted by moderately east-dipping Goonumbla Volcanic Complex on weste...
Orogenic growth, characterized by formation and forward propagation of fold-thrust belts foreland basins, is predicted wedge models thrust systems. The growth the Nanpanjiang belt basin system Indosinian orogenic in southwestern South China remains poorly understood. development underappreciated due to few constraints on structural styles, kinematics ages. Surface cross sections, seismic profil...
Reservoir characteristics and the occurrence mechanism of shale gas outside Sichuan Basin are research hotspots normally pressured shales in China. Taking on Anchang syncline from periphery as an example, X-ray diffraction, organic geochemistry, rock physical experiments were carried out to analyze reservoir their main geological controls shales. The mineralogical results show that studied main...
Abstract Palynological studies of lacustrine sediments in Eocene maar craters on the Sprendlinger Horst (Hesse, SW Germany) are complemented by 26 core samples from Groß-Zimmern. In addition, diatoms have been studied to assess palaeolimnological conditions. The palynomorph assemblage proves a middle age more or less coeval upper part nearby succession at Messel. includes 33 m massive finely la...
The relative timing between crustal extension and salt deposition can vary spatially along passive margin basins as continents unzip, or the locus of shifts toward embryonic ocean spreading center. Determining deposition, rifting, seafloor is often problematic due to diachronous nature ability fill pre-existing topography, subsequent flow deformation that salt. We here use 2D PSDM seismic data ...
As an essential component in shale, OM (organic matter) grains and their arrangements may play roles affecting the anisotropy of reservoir. However, are commonly treated as evenly distributed isotropic medium current studies, few works have been done to investigate detailed arrangement characteristics. In this study, terrestrial marine shale samples were collected from three different plays Chi...
The subsidence history of forearc and back-arc basins reflects the relationship between subduction kinematics, mantle dynamics, magmatism, crustal tectonics, surface processes. distinct contributions these processes to topography variations active margins during initiation, oceanic subduction, collision are less understood. We ran 2D elasto-visco-plastic numerical models including hydration sho...
sarygamesh basin one of the bulhary chay tributary take place in moghan plain, northeastern azarbyjan area in iran and south edge of kora- araz zone. aims of this research are study specificities and geomorphic evolution of sarygamesh basin, survey rivers work on structure and geologic formation, and corresponding hydrographic with earth structure. toward above aim is used to litologic, structu...
