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.?

Lithological control on water chemistry in karst aquifers of the Zagros Range, Iran
Abstract:
The Zagros Range of south-central Iran is characterized by long and regular anticlinal and synclinal folds. Most highlands are karstified limestone and dolomite aquifers, which are sandwiched between thick non-karstic marl, marlstone, manly limestone, gypsum and anhydrite formations. Hydrochemical data from 195 karst springs, emerging from five different karstic formations, were used to determine the factors controlling spring water quality. The size and boundaries of catchment area of each spring were determined using water balance and geological methods. The springs were classified based on water type and specific conductance; and discrimination analysis was performed on the major anions, cations, and the specific conductance of all the springs to confirm the proposed classification. The Piper diagram reveals bicarbonate, bicarbonate-dominant, sulphate-dominant, or chloride water type with specific conductances ranging from 190 to 13500S/cm. The lithology of the neighbouring formations and its extent of outcrop into the catchment area of the karst springs have a major effect on water quality. Large exposures of marl, marlstone, and manly limestone on the catchment area of the karst springs can change bicarbonate water to bicarbonate-sulphate, whereas gypsum and anhydrite produce sulphate-type waters. Salt domes, and saline water from adjacent lakes or alluvial aquifers are the main sources for chloride-type water.
