That tower karst, towerkarst, turmkarst is 1. a spectacular variety of karst landscape dominated by steep or vertical sided limestone towers each 30-300m high. by far the most extensive and best developed tower karst is the guangxi province of southern china. towers originate as residual cones and are then steepened by water table undercutting from surround alluviated plains. tectonic uplift matched by karst erosion then increases tower heights, but if uplift exceeds surface lowering the towers are raised to hillside locations and the landscape is rejuvenated to form a new generation of dolines and cone karst. many towers are riddled with relict caves at high levels, and with active caves through their bases [9]. 2. karst topography characterized by isolated residual limestone hills displaying numerous shapes (e.g., cone shaped, steep-sided) separated by areas of alluvium or other detrital sand; towers are generally forest-covered hills, and many have flat tops. they may form as isolated hills or in groups. 3. a type of karst topography, common in the tropics, in which the residual hills rise in steep-sided but flat-topped mounds (resembling towers) from intervening depressions or dolinas (sinkholes) [20]. synonyms: (french.) karst a tourelles, karst a tours; (german.) turmkarst, kegelkarst; (italian.) carsismo con forme residuali a torre; (spanish.) karst de torres; (turkish.) kuleli karst. see also cone karst; cupola karst; pinnacle karst; fengcong; fenglin.?

Dating of speleothems from deep parts of the world’s deepest cave – Krubera (Arabika Massif, Western Caucasus)
Abstract:

Results of 230Th (TIMS) dating of speleothems from the caves Krubera (the deepest cave in the world; -2191 m) and Kujbushevskaja in the Arabika Massif, Western Caucasus, are given in the paper. Most of dates are from samples taken from the deep part of Krubera Cave, between depths of 1630-2010 m (elevations of 629-246 m a.s.l.), which is important for elucidating evolution of karst systems in the area and its relation to changes of the base level (the Black Sea level). Obtained dates scatter through each of 1 to 7 zones of the marine isotopic scale and hit the know from the Eastern Alps periods of intense speleothems deposition (Holocene, 50-60 Ky, 67-80 Ky, 190-240 Ky, 250-280 Ky), as well as the periods of absence of dates (160-165 Ka; marine stage 6). The dates correspond to both, interglacial and glacial periods. The presence of two dates older than 200 Ky (max 276 Ky) from deep sites points to the fact that these deep parts of Krubera Cave already existed within the vadose zone before (and likely – much before) Middle Pleistocene.  Also, two samples from fossil passages located at elevations of 2016-1906 m a.s.l. are dated beyond the dating limits (>500,000 Ky). The results are consistent with a hypothesis that the early development of the karst system, which Krubera Cave is part of, is linked with the Late Miocene (Messinian) periods of an extremely low position of the sea level. The expressively vertical development of Krubera Cave is determined by intense uplift of the Arabika Massif in Pliocene-Pleistocene time, differentiated by blocks of the sub-Caucasian strike.
