That dating of cave sediments is determination of the age of development of caves is normally impossible. only the sediments they contain can be dated, and these must necessarily be younger than the containing passage. geomorphological correlations may allow more accurate dating of the cave erosion. the most useful dating method in current use is based upon a knowledge of the rates of decay of radioactive isotopes of uranium to thorium in stalagmites. this technique allows measurement of ages in material up to 350,000 years old. dating of stalagmites has confirmed that many cave ages lie beyond this range. electron spin resonance (esr) measures the cumulative effects of radiation that are partly a function of time and can give stalagmite ages back to about 900,000 years. palaeomagnetism may recognize events up to 2 million years old, but a sequence of palaeomagnetically dated sediments is required to allow identification of the actual ages [9].?

KARST HYDROGEOLOGY OF THE TAKAKA VALLEY, GOLDEN BAY, NORTHWEST NELSON

Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/speleogenesis.info/include/functions1.php on line 943
Abstract:
Upper Ordovician Arthur Marble and Oligocene Takaka Limestone contain extensive phreatic cave systems beneath the Takaka valley and Golden Bay. Half of all water flows in the Takaka valley pass through subterranean drainage conduits in carbonate rock. New Zealand's largest freshwater springs, the Waikoropupu Springs, are one surface expression of these karst systems. Other characteristics are dolines and submarine springs. A paleocave system developed in the Arthur Marble during the formation of the northwest Nelson peneplain in the Late Cretaceous and early Tertiary. Subsequent subsidence of the peneplain, and deposition of Motupipi Coal Measures, Takaka Limestone, and Tarakohe Mudstone, was followed by folding and faulting of the sequence in the Kaikoura Orogeny. Uplift and erosion in the Pleistocene brought the two carbonate rock formations within reach of groundwater movements. The paleocave system in Arthur Marble was reactivated during periods of glacial, low sea levels, and a smaller cave system formed in the overlying Takaka Limestone. Both systems interact and extend to more than 100 m below present sea level, forming the Arthur Marble - Takaka Limestone aquifer
