Le Chili, pays de karsts extrmes, 1994, Salomon, J. N.
Though Chile is a very large country, it hardly ever appears in speleological and karstological literature. This is due to the country's geological nature, which is essentially metamorphic and volcanic. Yet karstic phenomena are to be found iii gypsum and halite outcrops and in limestones. This is all the more interesting for science as Chile stretches latitudinally from the dry climate of Atacama desert in the north (1 mm/year a Iquique) to the hyper-hu-mid islands of Patagonia (>4000 mm/year).

Les glaciers de marbre de Patagonie, Chili : un karst subpolaire ocanique de la zone australe, 1999, Maire Richard, Ultima_esperanza_team
The karst areas of Chilean Patagonia have remained virtually unknown until now because of their remoteness and very inhospitable climate. They are mainly located in two islands, Diego de Almagro and Madre de Dios, between latitude 52 and 50 South, with a subpolar and stormy climate "tempered" by heavy oceanic precipitations (7 m/ year). In Diego de Almagro the Permian and Carboniferous limestones and dolomites have been transformed into marbles with lamprophyre dikes through contact metamorphism. Situated in the outer part of the archipelagoes, these long and narrow outcrops (0.5-2km wide) are located between volcano-sedimentary formations of Upper Paleozoic (West) and the Mesozoic Patagonian batholit (East). The corallian paleoreefs are part of an accretionary prism of the Gondwana paleo-continent. The surficial and underground karstification is one of the most spectacular ones in the world. The Karren (lapies) caused by the heavy rains can be 1-4 meter(s) wide and several hundred meters long for the solution runnels. Moreover, we can often observe solution karrens both due to rain and wind direction: flat karren (horizontal laminar flow), cascading ripples (sloping laminar flow) and profiled solution forms. The surficial solution velocity is about 3 mm/50 years (from old painting traces near the quarry of Guarello, Madre de Dios); and the lamprophyres dikes (Diego de Almagro) put in relief through corrosion indicate a 40-60 cm surficial solution since the melting of pleistocene glaciers.

Erosion et ruissellement sur karst nu en contexte subpolaire ocanique : les les calcaires de Patagonie (Magallanes, Chili), 2001, Hoblea Fabien, Jaillet Stphane, Maire Richard
During Ultima Patagonia project (2000) on Madre de Dios island karst (chile), runoff and erosion characteristics have been measured and followed on the field, to explain the hypertrophy and particularity (profiled shapes) of the marble and limestone karrens. Hydrologic and morphologic measures have been made on a little catchment (100 m2). In this subpolar oceanic context, it appears that evaporation rate on bare karst is low despite the strong wind and consequently runoff activity is particularly strong. These measures are compared to those made on karst tables and dykes originating from differential corrosion, that show moreover the wind part in the development of wind-profiled karrens, a special karst landscape unknown up to now. Surface karst denudation is about 100 mm / ka.

Vitesse de recul dun escarpement lapiaz (Ile Diego de Almagro, Patagonie, Chili),, 2003, Veress Mrton, Toth Gbor, Zentai Zoltn, Czpek Istvn
Backward rate of a marble side slope (Island Diego de Almagro, Chilean Patagonia) - Our research group measured the dissolution caused regressive velocity of the marbles side slope on one of the marble stripes on the island of Diego de Almagro. Using the time of ice melting and the width of rim bordering the edge of the sidewall the velocity of regression is 0,4-0,5 mm per year. This velocity of regression exceeds with an order of magnitude the velocity of denudation caused by dissolution on marble surface. Due to this fact, the marble stripes of the island become narrower to a bigger degree than they become shorter.

Evolution actuelle des phnomnes karstiques dans la Cordillera de la Sal (Atacama, Nord Chili), 2006, Sesiano Jean
New observations about the very slow present-day evolution of karstic phenomena in the Cordillera de la Sal (Atacama, Chile) - A second visit to the salt diapir in the Cordillera de la Sal, on the western margin of the Salar de Atacama was conducted 9 years after the first one. We noticed practically no change in the landscape morphology in that very arid region. A stainless steel piton driven at the base of a small cliff of rock salt was used to measure the salt dissolution rate. It did not show any extra thickness loss. A new passage system, partly underground, was discovered and mapped. Several swallow holes were observed, most of them half-filled with eolian sand. Undoubtedly they become active as soon as enough rain is collected at the surface. The underground water flows probably in the direction of the Salar in order to feed the water-table in the post evaporitic sediments, following the prominently N 140o oriented fracture system of the Cordillera de la Sal. Under the present climatic conditions, which are hyper-arid, observations on a time scale longer than the decade are essential to see changes in morphology.

Englacement, eustatisme et rajustements karstiques de la bordure sud de larchipel de Madre de Dios (Patagonie, Province ltima Esperanza, Chili, 2008, Jaillet S. , Maire R. , Brehier F. , Despain J. , Lans B. , Morel L. , Pernette Jf. , Ployon E. , Tourte B. , Patagonia U.
Glaciation, eustatics and karst readjustment at the southern edge of the Madre de Dios archipelago (Patagonia, Ultima Esperanza Province, Chile). In the channels of Patagonia (Chile), at a latitude of 50 S, lies the Madre de Dios archipelago, a group of islands with limestone zones with the southernmost caves on the planet. Over the course of three expeditions in 2000, 2006 and 2008, alpine caves, marine caves and spectacular karren fields were explored and found to contain karst features in a mountain and fiord environment. Precipitation of 8000 mm/yr and strong winds form exaggerated superficial karst forms. Above all, the legacy of the Quaternary glaciers (dynamics of glacier retreat, eustatic variations in sea level, isostatic rebound), is the subject of this article. At the convergence of the influences of the Andes mountains to the East and the Pacific ocean to the West, the karst with its surface and its subterranean and submarine forms, constitutes a key to the understanding of the landscape. We show that in each stage in this evolution (glacial retreat, sea level rise, isostatic rebound), the karst has developed forms that register 21,000 years of morphogenesis in this unique region.

PERIODICAL CERKNICA LAKE IN FRISCHLINS (1547-1590) WORK, 2009, Juni? Stanislav
Ljubljana rector Frischlins work about Cerknica Lake (1582- 1584) is described. Frischlins connections with other protestant and catholic researchers are put in the limelight. Frischlin wrote his most important astronomical work De astronomicae artis at Ljubljana. It was the first world-wide recognised scientific work produced at the area of modern Slovenia. Valvasor published comparatively long description of Frischlin work at Ljubljana with the special concern put on Frischilins poetry devoted to the secrets of periodical Cerknica Lake. $e speleologist Urbas partially translated Frischlin ode nearly two centuries after Valvasors publication. This pioneering discussion is devoted to Frischlins important contribution to 16th century subterranean karst research.
