L'hyperkarst des montagnes NakanaiModele d'evolution d'un reseau juvenile (gouffre Muruk) base sur des datations U / Th et paleomagnetiques des sediments, 2001, Audra Ph. , Lauritzen S. E. Rochette P.
Muruk is the deepest cave in the Southern hemisphere (1178 m)It extends through the Nakanai mountains and across large galleries, sometimes more than 50 m wideConsidering the important rainfall, very active uplifting and presence of a rainforest, Papua can be regarded as a hyperkarst with large morphological forms evolving very quicklyU/Th and paleomagnetic dating of sediments confirms this by assigning a very recent age to this cave system (100 to 200 ka)Muruk is a model of juvenile systems with a regularly inclined profile, unlike typical systems, and a monophasic evolution without an old perched levelThese characteristics are essential for understanding not only the first speleogenetic phases, but also the more evolved systems found throughout the world

Tracages dans le systeme Muruk-Berenice, montagnes Nakanai [Water tracing in the Muruk-Berenice system, Nakanai Mountains, New Britain, Papua New Guinea], 2001, Audra Phand. , Hoblea Fabien
The results of three dye tracings in the Muruk area led to approximate delimitation of the Berenice catchment and identification of some internal connectionsIt seems that the plateau above Arcturus cave feeds the Voie Lactee main drain, but unfortunately the forest destruction by a previous hurricane prevented us from identifying the boundary between the Berenice and Mayang catchmentsThe transit speeds of the dye were extremely fast as all the streams are mountain torrents rather than slow phreatic flows

Giant dolines of the Muller Plateau, Papua New Guinea, 2006, James Jm
The Muller Plateau lies within the Southern Highlands of Papua New Guinea, and is distinguished by its giant dolines. Many of these have exceptionally large dimensions and a morphology comparable to that of the megadolines of the Nakanai Mountains on New Britain and the tiankengs of the South China karst. They are all caprock dolines. The geology, physical geography and hydrology of the Muller Plateau are compared with those of the Nakanai Mountains and the South China karst. Proposed mechanisms for the formation of three groups (Rogorepo, Mamo and Atea) of giant dolines on the Muller Plateau are discussed. The Muller Plateau giant dolines, like the megadolines and the tiankengs, formed during the Pleistocene. The Muller Plateau dolines have formed in an environment that has many similarities to the other giant dolines. However, it is unlikely that they will ever evolve to the magnificence of the Nakanai megadolines or the aesthetics of the Chinese tiankengs, as a controlling factor in their development is a siltstone caprock and impure interbeds within the Darai Limestone.

Siphone tief im Dschungel: Bericht von einer Hhlenexpedition in den Urwald Neubritanniens, 2008, Meyer, U.
For more than 30 years, international expeditions have been exploring the limestone ranges of Newbritain. The enormous pits of Nare, Minye, Ora and Kavakuna are well known among cavers all over the world. They give entrance to the roaring underground rivers of the Nakanai Mountains. In 1995, French speleologists reached 1000 m for the first time in the southern hemisphere in the Casoar Cave System. But the known cave forms only part of the big collecteur that feeds the Berenice Spring deep inside the Galowe-Gorge. The Arcturus Cave also feeds this spring, as proven by dye trace. To realize the junction by diving was the goal of an international expedition early in 2007. This goal could not be reached, but by linking several nearby caves to Arcturus, a new cave system with 10416 m length and 518 m depth was established and named Wallaby. All in all, 9465 m of new passages in 14 different caves were explored during the expedition. 16 sumps were dived, 12 of these could be passed and 2866 m of dry galleries were surveyed behind sumps. The projected sampling and age determination of cave sediments was cancelled in the last minute due to missing sponsors.

The role of seismic activity in the formation of large underground cavities in the Muruk System, Nakanai Mountains, New Britain, Papua New Guinea, 2011, Audra, P.

Papua New Guinea is one of the world’s most active seismic areas. On the surface, huge landslides are found on mountainsides and steep canyons slopes. Underground large passages and megadolines result mainly from the erosion of soft limestones by underground streams, but seismic movements may accelerate their evolution. Morphological characteristics were derived from statistical data and field observations.


Speleogenesis in the hyperkarst of the Nakanai Mountains (New Britain, Papua New-Guinea). Evolution model of a juvenile system (Muruk Cave) inferred from U/Th and paleomagnetic dating, 2011, Audra P. , Lauritzen S. E. , Rochette P.

Muruk is the deepest cave in the Southern Hemisphere (1178 m of depth). It gives an access to go through the Nakanai Mountains and across large galleries, sometimes more than 50 m wide. Considering the important rainfall, the very active uplifting and the presence of a rainforest, Papua can be regarded as a hyperkarst, with large morphological forms evolving very quickly. U/Th and paleomagnetic dating on cave sediments confirm this point of view, assigning a very recent age to this cave system (100 to 200 kyr). Muruk is a model of juvenile systems with a regularly inclined profile and with a monophase evolution excluding any old perched level, unlike usual cave systems. These characteristics are essential for understanding not only the first speleogenetic phases, but also the more evolved systems found throughout the world.

Water tracing in the Muruk-Berenice system (Nakanai Mountains, New Britain, Papua New Guinea), 2011, Audra P. Hoblé, A F.

Three dye tracing have been carried out in the Nakanai Mountains to determine Berenice spring catchment area and some internal connections inside Muruk Cave. Andromede Cave belongs to Muruk-Berenice system, via Arcturus main drain. Due to special conditions in rainforest with difficult of moving, we made qualitative tracing using charcoal bags.


Expedition Vuvu 2010 ins Nakanai-Gebirge auf Neubritannien , 2011, Meyer, U.
In the spring of 2010 an international expedition visited the Nakanai Mountains in New Britain (Papua New Guinea). In the vicinity of the Matali River the two caves Bikbik and Liklik Vuvu, that both were found and explored by a French expedition in 1980, have been linked by diving to form the Wowo- System, now the second largest cave of New Britain with a length of 14.5 km and a depth well above 500 m (second only to the Kasoar-System). The team had to turn back in the large tunnel due to lack of time, still several kilometers from the Matali Gorge and more then 200 m above the assumed resurgence. Additionally a number of new caves were found and explored, among which Maare is probably most interesting. From its position and large dimensions it can be assumed, that it may be the headwaters of the Luse River, joining the Kavakuna River in the cave Ka2 and emerging in the big Matali resurgence, which has not yet been fully explored.
