The Zagros Fold and Thrust belt is one of the world's most prolific petroleum provinces. Most hydrocarbon reserves are stored in naturally fractured reservoirs such fracture systems can therefore have a significant impact on reservoir performance. Fractures important paths for fluid flow carbonate reservoirs. Fracture data were collected outcrops Kirkuk Group Oligocene age around Qara Chauq Sou...

From the 1970s, Dead Sea experienced severe halo-karstification and anthropogenic modifications. Progressively, but at an accelerating rate, subsidence, landslides, sinkholes have increased in number magnitude. The hazards’ triggering factors are terminal lake level lowering more than one meter per year dynamic equilibrium of hydrogeological system. Over Lisan peninsula, archived satellite imag...

Abstract The Western Balkans hosts the richest subterranean aquatic gastropod fauna in world. main factors shaping intraspecies diversity are thought to be isolation and endemism. In genus Belgrandiella , minute snails inhabiting waters springs Central Europe Balkans, molecular studies have shown much fewer valid species than previously anticipated. present study applies mitochondrial cytochrom...

of the Dalmatian coast type, formed primarily from karst limestone, Eastern Adriatic coast shows great diversity of habitats. This diversity is also influenced by the position of the Adriatic Basin, stretching from northwest to southeast, climatic differences along its length, and the direction of sea currents. Habitats in the submerged karst characteristic for the Croatian side of the Adriatic...

The mid-Cretaceous histories (origin, growth, death) of algal-rudist-stromatoporoid reef communities located on many Pacific Basin guyots are complex and controversial. These shallow water, tropical communities originated on volcanic edifices extruded during the Barremian-Albian, grew upward during edifice subsidenceftransgression throughout the Aptian, Albian and Cenomanian and several of them...

Abstract Although chalk aquifers are not too often associated with conduit flow, they highly productive groundwater systems and, like limestone aquifers, can be vulnerable to contamination when exposed land use activities. The Danish carbonate rocks generally recognized fractured and covered by thick Quaternary sediments. Fissure flow is pronounced, occurring in the upper 50–100 m due Pleistoce...

In this article, the temporal and spatial development of probable sinkholes in close vicinity a couple that occurred 2007 2018 Kozaklı (Nevşehir) geothermal field, which is one most important thermal tourism centers where treatment with radon gases mud can be carried out Central Anatolia, was investigated using multi-electrode resistivity method core drilling data. The primary water aquifer con...

Abstract Faults and fractures are a critical store pathway for groundwater in Ireland’s limestone bedrock aquifers either directly as conductive structures or indirectly the locus development of karst conduits. From quantitative analysis post-Devonian faults range lithological sequences, this report describes principal characteristics Cenozoic strike-slip joints, youngest most intrinsically wit...

Abstract. The Franconian Alb of SE Germany is characterized by large-scale exposures Jurassic shallow marine limestones and dolostones, which are frequently considered to be outcrop analogues for deep geothermal reservoir rocks in the North Alpine Foreland Basin farther south. However, burial history strata not well known as they were affected emersion, leading extensive erosion karstification ...

Atolls are faithful recorders helping us understand eustatic variations, the evolution of carbonate production through time, and changes in magmatic hotspots activity. Several early Cretaceous Mid-Pacific atolls were previously investigated ocean drilling, but due to low quality vintage seismic data available, few spatial constraints exist on their stratigraphic large-scale diagenesis. Here, we...
