The AA. describe a variety of raft cones that were discovered in the Paradise Chamber of the Sima de la Higuera Cave (Murcia, south-eastern Spain) based on their morphological and morphometric characteristics. These speleothems, dubbed double-tower

This work aims to examine the influence of the variability of the initial apertures on dissolutional growth of fissures and the evolving cave systems. To this end, the initial apertures were spatially uncorrelated and lognormally distributed
and the influence of the coefficient of variation of the aperture data (σ/μ) was investigated in several scenarios on the basis of a set of 4 realisations. It is found that a small degree of heterogeneity leads to cave patterns similar to those obtained with uniform

a variety of minerals formed inside the caves : calcite and aragonite, that yielded sequences of palaeo-environmental interest, and also barite and many others. These minerals are in part due to a phreatic thermal hypogeniccave forming phase, and in part
A combined geomorphological and mineralogical investigation has permitted a fairly detailed reconstruction of the various phases of evolution of these caves in Sardinia. Cave formation had already started in Cambrian times, but culminated
to later epigene overprinting in an oxidizing environment rich in polymetallic ores. Massive gypsum deposits, elsewhere typical of this kind of caves, are entirely absent due to dissolution during both the phreatic cave formation and the later epigenic
. The formation of the most important caves of this area probably started at the end of the Messinian under epigenic conditions. Possibly, those inherited caves enlarged slowly during the Quaternary in an intrastratal and confined hypogene karst system.
cycle and carved in the gypsum beds. Epigenic caves probably formed during this short intra-Messinian phase of emersion. Cave sediments contain benthonic and planctonic formaminiferal associations ranging in age from Burdigalian to Upper Pliocene
Cathedral Cave, Wellington Caves, New South Wales, Australia. A multiphase, non-fluvial cave
Australia ; Cave ; Geomorphology ; Inventory ; Karst ; Karstification ; New South Wales ; Palaeokarst ; Stratigraphy
Cathedral Cave is an outstanding example of a class of multiphase caves with largely non-fluvial origins. It is possible to recognize at least 10 significant phases of speleogenesis by morphostratigraphy, in addition to the 4 generations of cave
-filling palaeokarst deposits intersected by the cave. The cave we see today results from the progressive integration of a number of previously disconnected or poorly connected solution cavities.
This paper focuses on caves in Pleistocene carbonate conglomerates in Slovenia and for the first time defines them as eogenetic. The conglomerates show no deep burial that would resemble the mezogenetic stage of diagenesis and are still in the phase
of early diagenesis (i.e. eogenetic stage). Based on speleological analysis the eogenetic caves were grouped into four types; (1) linear stream caves, (2) shelter caves, (3) breakdown caves, and (4) vadose shafts. - (IKR)

A new history of cave development at Bungonia, N.S.W.
This paper presents a new developmental history of Bungonia caves based on cave morphology, clastic sediments in the caves and geological observations in the caves and their surroundings. Karst development at Bungonia can be traced back to at least
Magnetostratigraphy of cave sediments, Wyandotte Ridge, Crawford County, Indiana: towards a regional correlation

The polarity of 42 sediment samples obtained from 21 sites in Wyandotte Cave and five smaller satellite caves in Wyandotte Ridge, southern Indiana, is used as a basis for a magnetostratigraphic correlation with sediments in Mammoth Cave, Kentucky.
Punkva a jeji jeskynni systém v Amatérské jeskyni.. (Punkva River and its cave system of Amateur Cave)
The newly discovered cave system of the Punkva River in the Moravian Karst offered favourable conditions for the study of its relations to the environment. The Amateur Cave belongs to the longest in Europe and enables to complete the hydrogeological

The paper presents a denuded cave in the area of Podbojev laz, on the NW side of the Rakov Škocjan. The morphological properties of several sections of the denuded cave and its surroundings are described. It developed from an epiphreatic cave system
which used to function as an outflow cave system from the Rak valley. Morphometrical analysis of the slopes show that the denuded cave was developed in stages. As the surrounding surface is not flattened, the cave roof has been denuded gradually. - (L'A.).
Cave development under the influence of Pleistocene glaciation in the Dinarides - an example from Štirovača Ice Cave (Velebit Mt., Croatia)
Cave development ; Croatia ; Glacial features ; Glaciation ; Karst ; Karstification ; Palaeo-environment ; Pleistocene ; Records
The aim of this study is to examine the effect of Pleistocene glaciations on the speleogenesis of Štirovača Ice Cave, based on analyses of surface and cave morphology and of cave sediments, since it is well known that caves, and particularly clastic
sediments in caves, contain abundant information on speleogenesis and on the conditions of karstification. The AA. assume that Štirovača Ice Cave represents an important archive in regard to tha glacial history of the Velebit Mt.
There are almost 2000 caves in Hungary. The first part of the volume reviews the history of their exploration and the second presents the major caves, their origin, description of passages, geographical environment and touristic importance. The book
Geographic wonders : wind cave and jewel cave. The other national treasures of the Black Hills, South Dakota
Cave ; Geomorphology ; Nature park ; South Dakota ; United States of America
Although overshadowed by Mt. Rushmore National Memorial, which has become the place image of the Black Hills, Wind Cave National Park and Jewel Cave National Monument comprise two important national treasures set within the regional milieu
of the Black Hills. These caves serve as prime examples of how very weak geomorphic processes associated with solution weathering can become dominant and render a vast and complicated subterranean landscape in an environment insulated completely from sunlight
, rain, wind erosion, freezing/thawing, flowing water and bioturbation. Indeed, other than a few colonies of bats near the cave entrances, both caves are essentially devoid of life. - (IfL)
