In Great Britain, gypsum karst is widespread in the Late Permian (Zechstein) gypsum of north-eastern England. Here and offshore, a well-developed palacokarst with large breccia pipes was formed by dissolution of the underlying Permian... more
In the United Kingdom Permian and Triassic halite (rock salt) deposits have been affected by natural and artificial dissolution producing karstic landforms and subsidence. Brine springs from the Triassic salt have been exploited since... more
Regional-scale faulting, particularly in strike-slip tectonic regimes, is a relatively poorly constrained factor in the formation of caldera volcanoes. To examine interactions between structures associated with regional-tectonic... more
Surprisingly few natural hydrocarbon seeps have been identified in Australia's offshore basins despite studies spanning thirty years. Early studies of natural hydrocarbon seepage around the Australian margin were generally based on the... more
Archaeologists assessed eight Native American sites on Louisiana’s Gulf Coast for the effects of the MC252 Deepwater Horizon oil spill of 2010. Crude oil and dispersant used during the cleanup response were detected in redeposited... more
Single-pair differential synthetic aperture radar interferometry (DInSAR) as well as more advanced methods, such as persistent scatterer interferometry (PSI), allow vertical displacements to be detected at the sub-centimeter level. Since... more
Calatayud in NE Spain is an historically important city built on recent alluvial deposits underlain by gypsum and other soluble rocks. Since its foundation by the Muslims in 716 AD, the city development has been strongly influenced by... more
The burial of a basement sequence enriched in heat producing elements during thermal subsidence following rifting produces two concomitant changes in the thermal structure of the crust. Firstly, the burial of the enriched layer produces... more
Sinkholes usually have a higher probability of occurrence and a greater genetic diversity in evaporite terrains than in carbonate karst areas. This is because evaporites have a higher solubility and, commonly, a lower mechanical strength.... more
A B S T R A C T Ground subsidence and sinkhole collapse are phenomena affecting regions of karst geology worldwide. The rapid development of such phenomena around the Dead Sea in the last four decades poses a major geological hazard to... more
The Indonesian Throughflow (ITF) is a critical part of the global thermohaline conveyor. It plays a key role in transporting heat from the equatorial Pacific (the Indo-Pacific Warm Pool) to the Indian Ocean and exerts a major control on... more
Gypsum dissolves relatively quickly and gypsum karst can evolve on a rapid time scale that may be accelerated by human induced change, often resulting in severe subsidence damage. The area close to Inandık stream in Central Anato-lia,... more
A newly discovered phreatic cave system is described from Permian gypsum at Houtsay Quarry in the Vale of Eden, Cumbria. This is believed to be the first time gypsum caves have been described from England; the system has now been removed... more
Publié le 29 avril 2022 sur https://archeorient.hypotheses.org/18350. Les ruines du brise-lame principal du port forment les façades ouest et sud du port extérieur. Les blocs de couronnement de cet ouvrage culminent aujourd’hui à -2.5 à... more
