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.?

A 6000-year high-resolution climatic record from a stalagmite in Xiangshui Cave, Guilin, China
Abstract:
Middle-to late-Holocene palaeoclimate change has been reconstructed at high resolution by the analysis of the carbon and oxygen isotopes from a thermal ionization mass spectrometric (TIMS) U/Th dated stalagmite from Xiangshui Cave, near Guilin, Guangxi Province, China. The carbon and oxygen isotopic records from the stalagmite suggest that changes in the Asian monsoon since the middle Holocene (6000 BP) can be divided into two periods: (1) an interval from 6000 to 3800 BP when a strong East Asian summer monsoon gradually weakened and climate was relatively warm and humid; (2) a cool period from 3800 to 373 BP when the East Asian summer monsoon was relatively weak and the winter monsoon was probably relatively strong. This cooler interval was interspersed with a number of short warm periods. A This interpretation is largely based upon the general increase in 6180 values of the stalagmite between 6000 and 3800 BP and shifts in 6180 about a relatively heavy mean value between 3800 and 373 BP. The 6000 to 3800 BP trend is probably associated with decrease in precipitation and temperature subsequent to the mid-Holocene climatic optimum
