Abstract

Karsts of New-Zealand. New-Zealand presents numerous karts developped as well in ancient rocks (Paleozoic) as in recent ones (Oligocene). The stretching in latitude of the land, the high vegetal biodiversity and the strong rainfalls explain the importance of the karstification and the variety of the morphologies. Endokarsts are well developped , but many are still to explore. The polygonal karst of the King Country (North Island) in one hand, and the karsts of the Marble Mountains (Souh Island) in another one, are the most interesting. The possibilities of crossing of numerous datations (dendrochronology, speleothems, volcanism, etc.) and the location of these karsts in the south hemispher provide to these last exceptional paleo environmental recordering systems.
