The Lava Caves of Victoria, 1963, Ollier, C. D.

Many lava tunnels are found in the Western District of Victoria, associated with volcanic eruptions of Pleistocene to Recent age, and some are probably only a few thousand years old. All Australian volcanoes are now extinct, but the most recently active were probably erupting up to 5,000 years ago, that is after the arrival of the Australian aboriginal. The newness of the Victorian caves results in original features being preserved in fine detail. All known lava caves have now been surveyed, mainly by members of the Victorian Cave Exploration Society.

The Discovery, Exploration and Scientific Investigation of the Wellington Caves, New South Wales, 1963, Lane Edward A. , Richards Aola M.

Although research has been unable to establish a definite date of discovery for the limestone caves at Wellington, New South Wales, documentary evidence has placed it as 1828. The actual discovery could have been made earlier by soldiers or convicts from the Wellington Settlement, which dated from 1823. Whether the aborigines knew of the cave's existence before 1828 is uncertain, but likely, as in 1830 they referred to them as "Mulwang". A number of very small limestone caves were also discovered about the same time in the nearby Molong area. The Bungonia Caves, in the Marulan district near Goulburn, were first written about a short time later. On all the evidence available at present, the Wellington Caves can be considered to be the first of any size discovered on the mainland of Australia. The Wellington Caves are situated in a low, limestone outcrop about six miles south by road from the present town of Wellington, and approximately 190 miles west-north-west of Sydney. They are at an altitude of 1000 feet, about half a mile from the present bed of the Bell River, a tributary of the Macquarie River. One large cave and several small caves exist in the outcrop, and range in size from simple shafts to passages 200 to 300 feet long. Mining for phosphate has been carried out, resulting in extensive galleries, often unstable, at several levels. Two caves have been lit by electricity for the tourist trades; the Cathedral Cave, 400 feet long, maximum width 100 feet, and up to 50 feet high; and the smaller Gaden Cave. The Cathedral Cave contains what is believed to be the largest stalagmite in the world, "The Altar", which stands on a flat floor, is 100 feet round the base and almost touches the roof about 40 feet above. It appears that the name Cathedral was not applied to the cave until this century. The original names were "The Great Cave", "The Large Cave" or "The Main Cave". The Altar was named by Thomas Mitchell in 1830. See map of cave and Plate. Extensive Pleistocene bone deposits - a veritable mine of bone fragments - were found in 1830, and have been studied by palaeontologists almost continually ever since. These bone deposits introduced to the world the extinct marsupials of Australia, and have a special importance in view of the peculiar features of the living fauna of the continent. The names of many famous explorers and scientists are associated with this history, among the most prominent being Sir Thomas Mitchell and Sir Richard Owen. Anderson (1933) gives a brief outline of why the Wellington Caves fossil bone beds so rapidly attracted world-wide interest. During the 18th and early 19th Century, the great palaeontologist, Baron Georges Cuvier, and others, supposed that the earth had suffered a series of catastrophic changes in prehistoric times. As a result of each of these, the animals living in a certain area were destroyed, the area being repopulated from isolated portions of the earth that had escaped the catastrophe. The Bilical Deluge was believed to have been the most recent. Darwin, during the voyage of the Beagle around the world (1832-37), was struck by the abundance of Pleistocene mammalian fossils in South America, and also by the fact that, while these differed from living forms, and were in part of gigantic dimensions, they were closely related to present-day forms in that continent. Darwin's theory of descent with modification did not reconcile with the ideas of Cuvier and others. As the living mammalian fauna of Australia was even more distinctive than that of South America, it was a matter of importance and excitement to discover the nature of the mammals which had lived in Australia in the late Tertiary and Pleistocene.

Resemblances Between the Extinct "Cave Goat" (Eutheria, Bovidae) of the Balearic Islands and Phalangeroid Marsupials, 1971, Merrilees, D.

Information on the extinct "cave goat" (Myotragus balearicus Bate 1909) of the Balearic Islands is reviewed. Abundant remains of Myotragus balearicus are known from various deposits of late Quaternary (including Regent) ages. It had only a single pair of lower incisors, in this respect resembling Australian herbivorous marsupials, especially the bare nosed wombats.

Evolution of the Wellington Caves Landscape, 1973, Francis, G.

Wellington Caves, New South Wales (figure 1), have attracted scientific attention for more than a century, largely through discoveries in the cave sediments of bones from extinct animals. These bone discoveries provided impetus for a number of early speculations about the geomorphology of the caves area and its relationship to the caves. Notable among these was the conjecture of Mitchell (1839) that the valley floor sediments of the Bell River and the cave fills had been deposited during a marine transgression about one million years ago. The first systematic geomorphological work was carried out by Colditz (1943), who argued for two distinct relict erosion levels in the Bell Valley; the older level was assigned to the Lower Pliocene and the younger to the Upper Pliocene. Colditz considered that these levels provided evidence for two phases of uplift in late Tertiary times. More recently Frank (1971) made detailed studies of the cave sediments, and devoted some attention to landscape evolution. He believed that the Bell River had been captured by Catombal Creek, during the late Pliocene or early Pleistocene.

Extinct Peccary (Platygonus compressus LeConte) From a Central Kentucky Cave, 1975, Wilson Ronald C. , Guilday John E. , Branstetter John A.

Abstract: Darwin and Diprotodon: The Wellington Cave Fossils and the Law of Succession IN: Proceedings of the Linnean Society of New South Wales 104, 1980 for 1979:265-272, 1981, Dugan, Kathleen G.

The fossils from Wellington Caves, some of them 'giant', are well known to Australian speleologists, finds of importance for the study of Australian fauna from early discovered caves. What I think we did not appreciate was that the Wellington 'bones' have a place in the world history of science of significance also, the theme of this paper. Many of you will have watched the BBC-TV series on 'The Voyage of the Beagle'; much was made of the importance to Darwin in developing his theory of evolution of the fossils he found in southern South America. There fossils of giant relatives of sloths, llamas and armadillos helped to make clear to him the notion of the geological succession of life, a basic part of his theory along with the idea of natural selection to which the finches and the tortoises of the Galapagos Islands proved crucial. However it seems that Darwin was previously aware of the similar significance of the Wellington Caves bones for the law of succession from Charles Lyell's Principles of Geology which quotes William Clift's identifications of dasyures, wombats and kangaroos amongst them. The fact that these recently extinct animals were closely related to the distinctive modern marsupial fauna of Australia counted much against earlier conceptions such as Cuvier's catastrophic theory or Buckland's ideas of successive divine creations within a short time span. Watchers of the TV series will remember the devious role played by the palaeontologist, Sir Richard Owen, in organising public opposition to Darwin at the famous Oxford meeting of the British Association for the Advancement of Science. This article relates the series of rearguard actions of Owen to maintain that there was a fossil elephant component in the ancient Australian fauna, damaging to Darwinism. But the growing evidence from Australia, not all of it from caves, of course, finally extinguished this red herring, started by that doctrinaire N.S.W. colonial, the Reverend John Dunmore Lang.

Lattice Deformation and Curvature in Stalactitic Carbonate., 1983, Broughton Paul L.
The cause of lattice curvature is related to the nature of growth on a curved surface, peculiar to stalactites and stalagmites. Lattice curvature in stalactitic carbonate results from the coalescence of sub-parallel to divergent syntaxial overgrowth crystallites on the growing surface of stalactites and stalagmites. Moderate lattice mismatch results in an undulose extinction, or subcrystal domains, whereas more divergent growth favours marked lattice curvature recognized by its optical brush-extinction. Extreme lattice mismatch between the precursor crystallites results a columnar crystal boundary instead of lattice curvature.

The evolution of non-relictual tropical troglobites, 1987, Howarth Francis G.
The discovery of terrestrial troglobites living in caves on young oceanic islands with close epigean relatives living in nearby surface habitats offers unique opportunities to develop and test hypotheses concerning their evolution. Studies comparing the physiological ecology of troglobites with their epigean relatives suggest that troglobites are highly specialized to exploit resources within the system of interconnected medium-sized voids (mesocaverns) and only colonize cave passages (macrocaverns) with a stable, water vapor-saturated atmosphere. Few other animals can live in the mesocaverns. Rather than being relicts isolated in caves by the extinction of their epigean ancestral population, troglobites appear to evolve by a process called adaptive shift from species that are frequent accidentals in the mesocaverns.

Searching for extinction/recovery gradients: the Frasnian-Famennian interval, Mokra Section, Moravia, central Europe, 1996, Cejchan P, Hladil J,
A series of ancient seafloors colonized by diverse organisms has been documented from the Upper Devonian rocks of the Western Mokra Quarry. Situated in the southern tectonic closure of the Moravian Karst, the Frasnian-Famennian shallow carbonate ramps exhibit both Rhenish and Ukrainian affinities. Reconstruction of palaeo-sea floor horizons results in a series of 28 quadrats sufficient for further evaluation. Eighty-five taxa involved were scrutinized for abundance, occupied area, skeletal mass production and biomass production. The aim of the study was to determine whether the observed sequence of quadrats can be distinguished from a random one, and to discover any possible unidimensional gradient as a latent control. Monte Carlo simulations and a graph theoretical approach were utilized. Although the raw data seemed chaotic, the simulations demonstrated the observed sequence is not random. A significant influence of a hidden control is thus suggested. Fifteen characteristics of quadrats (e.g. diversity, number of taxa, vertical stratification of community, number of patches) were utilized for final interpretation. The gradient reconstructed by TSP algorithm reveals a significant crisis within the uppermost part of the Amphipora-bearing limestone

Mapping Chicxulub crater structure with gravity and seismic reflection data, 1998, Hildebrand A. R. , Pilkington M. , Ortizaleman C. , Chavez R. E. , Urrutiafucugauchi J. , Connors M. , Granielcastro E. , Camarazi A. , Halpenny J. F. , Niehaus D. ,
Aside from its significance in establishing the impact-mass extinction paradigm, the Chicxulub crater will probably come to exemplify the structure of large complex craters. Much of Chicxulub's structure may be mapped' by tying its gravity expression to seismic-reflection profiles revealing an [~]180 km diameter for the now-buried crater. The distribution of karst topography aids in outlining the peripheral crater structure as also revealed by the horizontal gradient of the gravity anomaly. The fracturing inferred to control groundwater flow is apparently related to subsidence of the crater fill. Modelling the crater's gravity expression based on a schematic structural model reveals that the crater fill is also responsible for the majority of the negative anomaly. The crater's melt sheet and central structural uplift are the other significant contributors to its gravity expression. The Chicxulub impact released [~]1.2 x 1031 ergs based on the observed collapsed disruption cavity of [~]86 km diameter reconstructed to an apparent disruption cavity (Dad) of [~]94 km diameter (equivalent to the excavation cavity) and an apparent transient cavity (Dat) of [~]80 km diameter. This impact energy, together with the observed [~]2 x 1011 g global Ir fluence in the Cretaceous-Tertiary (K-T) fireball layer indicates that the impactor was a comet estimated as massing [~]1.8 x 1018 g of [~]16.5 km diameter assuming a 0.6 gcm-3 density. Dust-induced darkness and cold, wind, giant waves, thermal pulses from the impact fireball and re-entering ejecta, acid rain, ozone-layer depletion, cooling from stratospheric aerosols, H2O greenhouse, CO2 greenhouse, poisons and mutagens, and oscillatory climate have been proposed as deleterious environmental effects of the Chicxulub impact with durations ranging from a few minutes to a million years. This succession of effects defines a temperature curve that is characteristic of large impacts. Although some patterns may be recognized in the K-T extinctions, and the survivorship rules changed across the boundary, relating specific environmental effects to species' extinctions is not yet possible. Geochemical records across the boundary support the occurrence a prompt thermal pulse, acid rain and a [~]5000 year-long greenhouse. The period of extinctions seems to extend into the earliest Tertiary

Late Pleistocene microtine rodents from Snake Creek Burial Cave, White Pine County, Nevada, 1998, Bell Cj, Mead Ji,
A total of 395 microtine rodent specimens recovered from Snake Creek Burial Cave (SCBC) are referred to Microtus SP. and Lemmiscus curtatus. Radiocarbon and Uranium series dates indicate an ae for these fossils of between 9460 160) yr. B.P. and 15,1000 700 yr, B.P. The sample of lower first molars of Lemmiscus includes 4-, 5-, and B-closed triangle morphotypes. Earlier reports of the 4-closed triangle morphotype are from Irvingtonian deposits in Colorado, Nevada, and New Mexico and from early Rancholabrean deposits in Washington. The morphotype is not known in living populations of Lemmiscus. SCBC specimens constitute the youngest record of the 4-closed triangle morphotype and are the only-specimens reported item the late Rancholabrean. Thc time of disappearance of Lemmiscus with this molar morphology is unknown, but populations with this morphotype possibly became extinct at or near the end of the Pleistocene

Karst lakes of the Protected Landscape Area - Biosphere Reserve Slovensky kras karst and Aggtelek National Park, 2001, Barancok P,
In the extent karst area belonging to the Protected Landscape Area - Biosphere Reserve Slovensky kras karst and Aggtelck National Park arc several lakes. They arc very significant biotopes. At present they arc extincted rapidly, their water surface is reduced, they are silted relatively quickly and they arc overgrown by wetland vegetation. In order to clarify the causes of their extinction the development of 3 takes of the area Slovensky kras karst - lakes Jastericicic jazero lake, Smradrave jazierko lake and Fardrova jama lake and 3 lakes of the area Aggtelck Karst - lakes Aggtelcki-to, voros-to and Kardos-to were evaluated. From the area Slovensky kras karst are well known 2 further lakes - Lucanske jazierko lake and Cierne jazero lake. Climatic changes and prevailingly negative impact of man have decisive influence on the development of all lakes in the mentioned area
