That cryokarst is 1. a non-karstic term. land surface with closed depression (usually small and shallow) formed by alternate freezing and thawing of permafrost or ground-ice overlying different rock, including limestone. the term 'cryokarst' is more common in europe while the term 'thermokarst' is used in america [20]. 2. a karst-like periglacial, or formerly periglacial, landscape superimposed upon unconsolidated, superficial deposits. cryokarst is characterized by small depressions or pits that develop due to settlement of overlying deposits into voids formed by the melting of entrapped ice. also known as thermokarst [9]. synonyms: (french.) cryokarst, thermokarst; (german.) thermokarst, cryokarst; (greek.) thermokarst; (italian.) criocarsismo; (russian.) termokarst, criokarst; (spanish.) criokarst, thermokarst; (turkish.) don karsti; (yugoslavian.) toplotni krs, temokarst.?

Subsidence problems in route design and construction, 1972,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/speleogenesis.info/include/functions1.php on line 943
Malkin Alexander Bernard, Wood John Charles,
The paper reviews the main causes of ground subsidence as it affects route design and construction in the United Kingdom. Investigation techniques and remedial measures are discussed in relation to both natural and mining subsidence. In addition to the common occurrence of subsidence problems in the coalfields, emphasis is placed on their presence elsewhere in the country. Natural subsidence problems are associated mainly with carbonate and saliferous rocks but mining activity has taken place at various times at numerous geological horizons for a variety of minerals. Future mining activity is likely to involve fewer minerals but will still be dominated by the coal industry. Experience has shown that the conflicting interests of route planners and mineral operators can usually be resolved by negotiation, accompanied in some cases by compensation

Observations at the Blue Waterholes, March 1965 - April 1969, and Limestone Solution on Cooleman Plain, N.S.W., 1972,

Jennings, J. N.

After brief descriptions of the geomorphology of the Cooleman Plain karst and in particular of the Blue Waterholes, the methods adopted to analyse the functioning of these major risings are detailed. The discharge regime of Cave Creek below them is oceanic pluvial in type perturbed by drought and snow. There is much annual variation both in seasonal incidence and total amount, with catchment efficiency correspondingly variable. Suspended sediment concentration is even more erratic and monthly determinations are inadequate for calculating corrasional denudation rates. Mean concentrations of suspended solids are about 1/18th of solute load. Total dissolved salts have a strong inverse relationship with discharge, and mean values are high compared with those for other catchments in eastern Australia but none of these determinations are from limestone catchments. Sodium, potassium, and chlorine contents are low compared with the same catchments but silica is relatively high. The ratio of alkaline earths to alkalis indicate that Cave Creek carries carbonate waters and there is an inverse regression of the ratio on discharge. There is inverse correlation of total hardness on discharge likewise due to concentration of surface waters by evaporation in dry periods, together with reduced underground solution rate at times of large, rapid flow. The spring waters remain aggressive. Close regressions of hardness on specific conductivity now permit the latter to be determined in the place of the former. Much evidence converges to indicate that all the springs at the Blue Waterholes are fed from the same conduit. The intermittent flow which comes down the North Branch on the surface to the Blue Waterholes differs significantly in many characters from the spring waters. Rates of Ca + M carbonate equivalent removal vary directly with discharge since hardness varies much less than does water volume. These gross rates have to be adjusted for (a) atmospheric salts entering the karst directly, (b) peripheral solute inputs from the non-karst two-thirds of the catchment and (c) subjacent karst solution before they can be taken as a measure of exposed karst denudation. The methods for achieving this are set out. The total corrections amount to about one third of the total hardness, though the correction for subjacent karst on its own lies within the experimental error of the investigation. The residual rate of limestone removal from the exposed karst also shows a winter/spring high rate and a summer/autumn low rate but the seasonal incidence and annual total varied very much from year to year. In comparison with results from karsts in broadly similar climate, the seasonal rhythm conforms and so does the high proportion (78%) of the solution taking place at or close to the surface. This reduces the importance of the impounded condition of this small karst but supports the use of karst denudation rate as a measure of surface lowering. Cave passage solution may however be more important in impounded karst than its absolute contribution might suggest, by promoting rapid development of underground circulation. The mean value of limestone removal is low for the climatic type and this is probably due to high evapotranspirational loss as well as to the process of eliminating atmospheric, peripheral non-karst and subjacent karst contributions. The difficulties of applying modern solution removal rate to the historical geomorphology of this karst are made evident; at the same time even crude extrapolations are shown to isolate problems valuably.


The evolution of the Eastern North American Isopods of the Genus Asellus (Crustacea: Asellidae)., 1973,

Fleming Laurence E.
This paper is the second in the three part series dealing with the evolution of the North American isopods of the genus Asellus. The generic status of Asellus is discussed with emphasis placed on the newly proposed genera of Henry and Magniez (1968). Use is made of comparative anatomical and where feasible statistical methods during this investigation. The first, shorter portion of the study deals with the presentation of evidence supporting the viewpoint that if 'Pseudobaicalasellus" is to be considered a valid genus then it must include the members of the Cannulus Group of Steeves (1965). The second portion of the study is concerned with the determination of the generic status of the eastern North American isopods. From the data presented it is felt that it is inadvisable to elevate species; groups of Asellus to the rank of genera. A generic diagnosis of the genus Asellus is presented. A list of North American species of the genus Asellus as well as a key to North American species of Asellus is included. The reduction to synonymy of certain nominal species of the genus Asellus is also given.

Investigations into the watertightness of the proposed Gordon-above-Olga hydro-electric storage South-west Tasmania, 1974,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/speleogenesis.info/include/functions1.php on line 943
Roberts Glyn T. , Andric Miodrag,
The Gordon-above-Olga scheme is one of several major hydro-electric developments under investigation in the south-west of Tasmania. The proposed storage area includes a zone of Palaeozoic limestone forming part of the eastern limb of a synclinal structure which provided a potential for the existence of leakage paths capable of threatening the viability of the scheme. The geology of the area is described and the methods used in assessing the likelihood of existence of subjacent karst are detailed. The conclusion is drawn on several grounds that neither recent nor ancient activity is likely to have markedly affected the limestone through the synclinorium. In consequence the water-tightness of the proposed reservoir is predicted
