That stegamite is a speleothem projecting upwards from a cave floor in the form of a calcite ridge. a medial crack appears along the top of the ridge where water is thought to be forced from the speleothem under capillary action [25].?

Geochemical methods for distinguishing surface water from groundwater in the Knox Aquifer System, 2002,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/speleogenesis.info/include/functions1.php on line 943
Redwine J. C. , Howell J. R. ,
The Knox Group, a thick package of Cambro-Ordovician rocks, occurs over a wide geographic area in the southeastern US. Characteristics of the Knox Group include strong structural control on porosity and permeability, deep near-vertical solution features, great depth of water circulation, dolomite, as well as limestone, hosting the karstic features, and extreme anistropy and heterogeneity. In this study, geochemical methods were used to distinguish ambient groundwater, in the Knox aquifer from surface water, specifically, water leaking from the Logan Martin resevoir in east-central Alabama. Major cations and anions, as well as stable isotopes of hydrogen and oxygen, were used to distinguish lake water from groundwater, and to determine mixed waters. Lake water and groundwater components for mixed waters were calculated, and mapped in plan view. A relatively narrow zone of mixing occurs in the vicinity of Logan Martin dam in map view, which is consistent with the hydrogological conceptual model of deep near-vertical solution-widened fractures (fissures), oriented east-norteast and to a lesser extent north-west, in a much less permeable dolomite matrix

Cyclic sequences, events and evolution of the Sino-Korean plate, with a discussion on the evolution of molar-tooth carbonates, phosphorites and source rocks, 2003,

Meng X. H. , Ge M. ,
This paper gives an account of the research that the authors conducted on the cyclic sequences, events and evolutionary history from Proterozoic to Meso-Cenozoic in the Sino-Korean plate based on the principle of the Cosmos-Earth System. The authors divided this plate into 20 super-cyclic or super-mega-cyclic periods and more than 100 Oort periods. The research focused on important sea flooding events, uplift interruption events, tilting movement events, molar-tooth carbonate events, thermal events, polarity reversal events, karst events, volcanic explosion events and storm events, as well as types of resource areas and paleotectonic evolution. By means of the isochronous theory of the Cosmos-Earth System periodicity and based on long-excentricity and periodicity, the authors elaborately studied the paleogeographic evolution of the aulacogen of the Sino-Korean plate, the oolitic beach platform formation, the development of foreland basin and continental rift valley basin, and reconstructed the evolution of tectonic paleogeography and stratigraphic framework in the Sino-Korean plate in terms of evolutionary maps. Finally; the authors gave a profound discussion on the formation and development of molar-tooth carbonates, phosphorites and source rocks
