Did you know?

That internal drainage is drainage in a closed basin and not reaching the sea [16]. it is common in maturely karsted terranes where surface water bodies are relatively nonexistent.?

Messinian event in the black sea, 1979, Hsu Kenneth J. , Giovanoli Federico,
Three holes were drilled during the 1975 DSDP Leg 42B drilling the Black Sea. A section from Hole 380, at 2107 m water depth on the western edge of the abyssal plain, is 1074 m thick, and provides the most complete stratigraphic section. Dating of the sediments is based upon (1) fossil evidence from pollen, crustaceans, benthic foraminifera, and diatoms, (2) correlation with climatic changes and with unusual isochronous events that have been dated elsewhere, (3) paleomagnetic data, and (4) estimates of sedimentation rate.The history of Black Sea sedimentation recorded by the DSDP cores includes black shale sedimentation during the Late Miocene, followed by periodic chemical sedimentation from Late Miocene to Early Quaternary, and a change to dominantly terrigenous sedimentation from the Middle Quaternary. These hemipelagic and turbiditic sediments were deposited in lacustrine and brackish marine environments. The Messinian sediments, however, consist of stromatolitic dolomite, oolitic sands, and coarse gravels, deposited in supratidal and intertidal environments. The intercalation of the shallow-water sediments in a deep-water sequence suggests a drastic lowering of the water-level within the Black Sea basin during the Messinian so that the edge of the present abyssal plain was then the edge of a shallow lake.The Messinian draw-down phase of the Black Sea was in existence for about 100,000 years during the Lago-Mare stage of the salinity crisis. The evaporated waters formed an alkaline lake before it was drowned by a brackish marine transgression correlative to the Trubi transgression of the Mediterranean

Microbial communities associated with hydromagnesite and needle-fiber aragonite deposits in a karstic cave (Altamira, northern Spain), 1999, Canaveras Jc, Hoyos M, Sanchezmoral S, Sanzrubio E, Bedoya J, Soler V, Groth I, Schumann P, Laiz L, Gonzalez I, Sainzjimenez C,
Microbial communities, where Streptomyces species predominate, were found in association with hydromagnesite, Mg-5(CO3)(4)(OH)(2). 4H(2)O, and needle-fiber aragonite deposits in an Altamira cave. The ability to precipitate calcium carbonate in laboratory cultures suggests that these and other bacteria present in the cave may play a role in the formation of moonmilk deposits

Phnomnes de karstification observs dans une cavit artificielle du Rincn Blanco (Argentine), 2000, Barredo, Silviap.
The Rincon Blanco subbasin is located in San Juan Province, Argentina, between 69 15' west by 314' to 31 33' south and is characterised by a non marine continental infilling. During the Tertiary times it underwent compressional deformation folding it into a tight north-_south trending syncline. The whole sedimentary sequence is comprised of coarse-grained units interfingered with sandstones and shales. In particular, these latter were deposited in an alkaline lake and are composed of carbonate and organic rich strata. These characteristic lacustrine facies bear bituminous shales widely known as "Rincon Blanco oil slates". During the 1950' s and 1970' s, they were densely explored resulting in a number of galleries that presently are abandoned. They were cut in the bituminous rocks exposing west-east and southeast-northwest systems of minor faults and local fractures. These discontinuities permitted the inflow of meteoric waters through the overlying layers and into these artificial caves, thus resulting in carbonate cement dissolution, and, re-precipitation as tiny stalactites, stalagmites, thick travertine deposits in the floor with incipient microchannels accompanied by pools (gurs) with pearls and botroidal-like concretions. Several solutional speleothems are also found and correspond to ceiling and wall pockets and floor pits. This phenomena seemed to be related to acidic water coming from small discharges and flowing through the network of integrated tectonic openings to the innermost tunnel sections where humid air reaches saturation. Water trickling resulting from condensation produces erosional features and, together with dropping and occasional flows, the speleothems. Events of slight flow turbulence in some enlarged fractures are also inferred by the presence of ceiling and floor dissolutional features.
