That gypsum karst is a karst landscape developed on, or perhaps above, gypsum or similar evaporite rock sequences. dissolution of gypsum by ground water in buried, interstratal, situations is common and the effects of such dissolution may be expressed at the land surface in the form of subsidence depressions. there are extensive areas of gypsum karst in north america and the ukraine but british examples are limited to rare caves, exposed by quarrying, and subsidence depressions above dissolved gypsum beds, such as those around ripon, yorkshire [9].?

Quaternary alluvial sinkholes: Record of environmental conditions of karst development, examples from the Ebro Basin, Spain , 2012, Soriano M. A. , Luzon A. , Yuste A. , Pocovı, A. , Perez A. , Simon J. L. , Gil H.

The central Ebro Basin is an exceptional region for studying karstification through time and under different environmental conditions, as sinkholes have been developing since the Early Pleistocene. Knowledge of active sinkholes is complemented with research on paleosinkholes and contemporary deposits. Sedimentological, mineralogical, geomorphological and structural approaches permit interpretation of the natural environmental conditions that favored karst in the past and the main genetic mechanisms involved. The sedimentary features of Pleistocene terraces indicate that they were deposited by a gravel braided fluvial system characterized by higher water and sediment availability than today, probably related to meltwater flows coming from glaciated source areas, mainly in the Pyrenees. Genesis of paleosinkholes was mainly linked to this high water supply. Some of them acted as small lakes where fine sediments are exceptionally well conserved to give clues about environmental conditions. The neoformation of palygorskite and sepiolite suggests arid to semiarid climatic conditions, in agreement with the idea of cold glacial episodes. During Pleistocene times, development of sinkholes was influenced by tectonics. Currently, the genesis and evolution of numerous sinkholes are also influenced by water supplies from human activities such as irrigation or urbanization, sharply changing the nearly steady state exhibited in the past


Origin of the interstitial isopod Microcharon (Crustacea, Microparasellidae) from the western Languedoc and the northern Pyrenees (France) with the description of two new species, 2013, Nicole Coineau, Claude Boutin, Malvina Artheau

The interstitial groundwater genus Microcharon (Crustacea, Isopoda, Microparasellidae) is highly diversified in southern France. A new species,Microcharon boulanouari n. sp. is described from the Aude River, whereas specimens from the Lachein River in the central Pyrenees are reassigned to another species, M. ariegensis new to Science. Microcharon boulanouarin. sp. is closely related to the species of the group rouchi and may belong to the phylogenetic western Mediterranean lineage. The two-step model of colonization and evolution provides an understanding of the origin and age of this stygobite. Microcharon boulanouari n. sp. is derived from marine ancestors that lived in the interstitial littoral shallow bottoms of the Atlantic embayment which covered southwestern France at the very beginning of the early Eocene period. Both the regression of this gulf at the start of the Eocene and the Pyrenees uplift may have played a major role in the evolutionary history through vicariance of Microcharon boulanouari n. sp. and of the northern Pyrenean species of the grouprouchi.
