That fengcong; fengcong karst is (chinese.) 1. a karst, conspicuous in china, that is identified by its clustered limestone hills. fengcong (pronounced 'fungston'), which translates as 'peak cluster', is a mature karst normally developed during long uninterrupted periods of rapid dissolution in wet tropical environments with high levels of biogenic soil carbon dioxide. the chinese classify karst by the hill or peak density, in contrast to the western classification by hill shape. fencong is almost the equivalent of cone karst; its closely packed hills are conical rather than hemispherical, with intervening dolines and disjointed valleys. the major occurrences are in guizhou and guangxi, in southern china. some cones in guangxi are so steep that they have been termed fengcong tower karst, but this concept is best avoided [9]. 2. tower karst characterized as peak cluster because the individual karst towers appear to be grouped together in clusters. closed depression among the peaks are common [4]. see also fenglin; fungling; mogote; tower karst.?

Stable isotopic variation of storm discharge from a perennial karst spring, Indiana

Abstract:
Oxygen and deuterium isotopes and major-ion chemistry of water from a large karst spring were used in an attempt to decipher water recharge, transmission, and storage characteristics of a karst aquifer system. Ionic concentrations and isotopic data indicated that the bulk of discharge during peak flow was derived from groundwater storage. Isotopic hydrograph separation of storm flow revealed that maximum rainwater contribution to discharge was 18 to 24 hours after peak flow and rainwater contributed 20 to 25% of spring discharge over the monitoring periods. Water released from phreatic and vadose conduit storage may have contributed to discharge with the onset of storm flow, while water from soil moisture and epikarst storage may have arrived during initial discharge recession
