Humid temperate impounded karst , sub-humid temperat syngenetic karst , arid temperate karst
A field symposium of IGCP299 will be held in Australia from 4 to 18 December 1992.This will allow members of IGCP299 to examine a wide range of karst types in southern Australia and to relate these to karst landforms already studied by the project. Papers dealing with similar karst types abroad can be presented during the symposium , and thus comparisons and correlations will be facilitated. We invite you to attend and encourage you to submit your ideas and papers at an early date.
Three principal karst types are widespread in Australia:
1.Small impounded karst or karst barre developed in Palaeozoic limestones of the Eastern Highlands of Australia. Examples of this type are Jenolan , Cooleman Plain and Buchan.
2.Syngenetic karst developed in aeolian calcarenites of Tertiary age in coastal Southern Australia. Examples of this type are Naracoorte , Bat Ridges , and Margaret River.
3. Arid zone karst developed in limestones of widely varying age from Tertiary to Palaeozoic. Examples of this type are the Nullarbor Plain , the Kimberleys , the Barkly Tableland and the Cape Range.
This combined field symposium and excursion will visit one example of each type of karst-- Buchan, Naracoorte and Nullarbor. These karsts all lie in the cool temperate part of Southern Australia , and experience a predominantly Mediterranean climate. Annual rainfall ranges from 100mm on the Nullarbor to about 800mm at Buchan. Landscape relief ranges from less than 5m on the Nullarbor to about 100m at Buchan.
Buchan is a typical impounded karst with an area of about 50 km2 and over 350 caves. Recent work there suggests that many of the karst features may be of Tertiary age, and there is thus a long geomorphic history of valley incision and aggradation which may reflect uplift history. There are well developed tourist caves here with permanent springs.
Naracoorte is one of the best examples of karst developed in aeolian calcarenite. The extensive caves and cenotes ( numbering around 100 ) are formed in lithified beach ridges of late Tertiary to Pleistocene age. Extensive formations and marsupial fossil material have led to the development and expansion of tourist caves here.
The Nullarbor is Australia's most extensive karst(200,000km2) but has surprisingly few caves for its area (approx.220). It does , however , contain several large caves (up to 11km long) which descend to the watertable at about 100m depth. There are well developed halite, gypsum and ancient calcite formations in the caves , as well as extensive saline lakes. Remains of aboriginal occupation include flint quarries and some of the oldest parietal are in the world. At present a World Heritag nomination is being prepared for the Nullarbor Plain.
Day 1: Meet in Melbourne 0900. Briefing in morning at Melbourne University , afternoon drive to Buchan. Stay at "Homeleigh"(caving field house).
Day 2-3: Visit to karst sites at Buchan, including tourist caves and some wild caves in Buchan Reserve. Karst spring monitoring and surface karst features at Murrindal. Chronology of caves and terraces. Management issues.
Day 4: Drive from Buchan to Warrnambool. Overnight at cabins.
Day 5: Warrnambool to Naracoorte karst via Ewen Ponds and other karst cenotes. Cave management and water pollution. Tourist cave development. Overnight at cabins.
Day 6: Naracoorte to Clare via Murray Bridge and Nuriootpa. Overnight at Clare caravan park (on-site caravans or cabins).
Day 7: Clare to Ceduna. Meet South Australian NPWS staff. Overnight in cabins.
Day 8: Start Nullarbor Plain section. Ceduna to Eucla via Head of Bight and Weebubbie Cave. Camp at Eucla coastal dunefield.
Day 9: Eucla to Abrakurrie Cave. Camp at Thampanna Cave.
Day 10: Thampanna Cave and Kelly Cave. Camp at Thampanna Cave.
Day 11: Witches and Webb Caves. Camp at Eucla Motel.
Day 12: Eucla to Koonalda Cave. Camp overnight at Nullarbor Station.
Day 13: Nullarbor Station to Diprose Caves , afternoon to Ceduna. Dinner and discussion re World Heritage listing for Nullarbor karst. Overnight in cabins.
Day 14 ,15: Ceduna to Adelaide. Excursion terminates at airport or city centre.
COST PER PERSON
AUS$2250 includes all publications , transport , meals and accommodation from the start in Melbourne to the finish in Adelaide (single room supplement $600). This cost estimate may have to be revised if fuel prices and vehicle costs increase before December 1992. Note that you will be responsible for arranging and paying for your transport to Melbourne and from Adelaide to your point of origin. We will arrange one night's motel accommodation (at your expense-approx.$120 for two nights , twin share) in each of Melbourne and Adelaide. All participants will be required to provide proof of adequate travel insurance; we can organize this at the time of booking(approx. $120 per person for three weeks).
TRAVEL AND VISAS
We will use on-site caravans or cabins wherever possible and especially on days with long drives. These provide single beds on a shared room basis with bathroom facilities. Electric power (240v) is available for charging batteries (lights , flashguns ,video). On the Nullarbor we will be camping and we will supply tents , foam sleeping mats and sleeping bags. Meals served will be continental breakfasts , sandwich lunches and cooked evening meals. Tea , coffee and fruit juices will be served. Alcoholic beverages will be at your expense. The Naracoorte area and the Clare valley of South Australia produce some of Australia's best red and white table wines.
Personal luggage will be restricted to one large soft rucksack or bag and a day pack. We will supply caving helmets and electric lights. You will have to bring protective clothing(overalls or similar) and boots. Ladders and ropes will be used on a few short pitches of less than 15m.
Registrants who are not Australian citizens should contact their travel agent or the Australian High Commission in their country regarding the need for a visa to enter Australia. Invitations will be arranged by the Organizing Committee.
