That doline; sinkhole is a basin- or funnel-shaped hollow in limestone, ranging in diameter from a few meters up to a kilometer and in depth from a few to several hundred meters. some dolines are gentle grassy hollows; others are rocky cliff-bounded basins. a distinction may be made by direct solution of the limestone surface zone, (solution dolines), and those formed by collapse over a cave, (collapse dolines), but it is generally not possible to establish the origin of individual examples [10]. solutional enlargement is either circular in plan, if there is one dominant vertical joint, or otherwise irregular if there are several and can achieve dimensions of up to 1,000 meters in diameter and 100 meters deep. where a karst bedrock is covered by superficial deposits, solutional enlargement permits the latter to subside into vertical fissures, creating subsidence cones or alluvial dolines, whose slopes are unstable because of the unconsolidated nature of the surface material. the bedrock remains covered in the first instance. dolines are also formed by the large-scale subsidence caused by cave roof-collapse of near-surface caverns; in this instance, the collapse doline, the sides are cliff-like and the floor composed of the irregular blocks from the fragmented roof. cave roof-collapse is considered a relatively rare phenomenon. closed depressions receiving a stream are known as swallow holes or stream sinks. a doline which is largely dependent upon snow for solution-enlargement is known as a kotlici or schneedoline [19]. in america most dolines are referred to as sinks or sinkholes. see also jama; pit; ponor; sink, sinkhole; stream sink; swallet; swallow hole; sumidero. synonyms: (french.) doline; (german.) dolinen, karsttrichter; (greek.) tholene; (italian.) dolina, pozzo naturale; (russian.) karstovaja voronka, karstovaja kotlovina; (spanish.) dolina; (turkish.) duden, kokurdan, huni; (yugoslavian.) vrtaca, ponikva, dolac, do, duliba, kotlic, konta.?

Speleogenesis of the Mammont cave system, Kentucky, USA

Abstract:
The Mammoth Cave System, in southwestern Kentucky, USA, is located in carbonate rocks of Mississippian (early Carboniferous) age, which dip less that one degree toward the northwest into the Illinois structural basin. The cave is contained within the Chester Upland, a fluvially dissected plateau of limestones and dolomites capped by clastic rocks. However, much of the groundwater recharge to the cave today and in the past has been from the nearby karst surface of the Pennyroyal Plateau, up-dip from the Chester Upland, where the insoluble cap-rock has been removed by erosion, exposing the carbonate rocks over a broad surface. The local bedrock is very prominently bedded, with very few large fractures, and as a result the cave passages are sinuous canyons and tubes, interspersed with vertical shafts that have developed downward in sequence, bed by bed. Passages of vadose origin are oriented almost invariably down the local dip, which is complicated by many irregularities superimposed on the regional dip. Phreatic passages show no inherent relation to the dip and are mostly oriented at very shallow angles to the strike direction. Depth of cave development below the water table is limited to a few tens of meters by the small amount of structural deformation. Dating of sediment shows that most of the earliest passages probably formed during the late Pliocene Epoch, although the very highest passages may be considerably older. These passages are few but large, and consist mainly of wide canyons and tubes that were later almost filled with silt, sand, and gravel during periods of regional aggradation. Diversion of drainage into the Ohio River by glacial ice during the early Pleistocene caused rapid entrenchment of the Ohio and its tributaries in the Mammoth Cave region. Passages became much more numerous as the landscape was dissected and as erosional base levels fluctuated more rapidly. Several major passage levels developed during periods of relatively static base level. The Mammoth Cave System thus provides many clues to the geomorphic history of the surrounding region.
