The geo-ecology of three Hungarian
karsts
Vol 25 (3) pp 113 - 117
Abstract: The sensitivity of karst
systems to human activities has become increasingly apparent as a result of
research during the 1980s and 1990s. Environmental processes are very rapid on
karst, and non-karstic materials integrate quickly into the karst system,
modifying and damaging the natural processes and forms. This paper presents
some results of research into karst geo-ecological systems in three Hungarian
karst areas.

Morphometric
studies of bell hole development on Cayman Brac
Vol 25 (3) pp 119 - 130
Abstract: Bell holes are cylindrical cavities that extend vertically upwards
into ceilings of caves. They have been reported only in the humid tropics. The
processes responsible for their formation are not fully identified; different
hypotheses have suggested mechanical, chemical or biological action but none of
these appears to explain the holes satisfactorily. On the Caribbean island of
Cayman Brac bell holes appear to be distributed at random in the entrance zones
of certain caves. The environment in which these holes formed and developed is
subaerial rather than subaqueous. Fifty-five bell holes from five sample caves
were measured in detail with a graduated gauge; profiles were drawn and volumes
calculated for each. Bell holes in four of the caves displayed similar
morphometry, whereas the holes in the fifth cave were significantly different
in size but not shape. All appear to be dissolutional rather than erosional
features. Dissolution, enhanced or not by microbiological activity, is thought
to take place in a thin film of condensation water.

Features of gypsum caves and karst at Pinega (Russia) and
Ripon (England)
Vol 25 (3) pp 131 - 140
Abstract: A profusion of
collapsed dolines and subsidence hollows characterises the gypsum karst around
Ripon in Yorkshire; clearly there are caves beneath the area, but none is
accessible. In arctic Russia, the Pinega karst has many gypsum caves, among
which some of the larger passages appear to have been formed by subglacial
meltwater. The environments of the two sites are comparable, and one possible
implication is that the unseen caves at Ripon may also be of Pleistocene
subglacial origin.

Trollers Gill, Wharfedale, North Yorkshire: its
geology, caves and hydrology
Vol 25 (3) pp 141 - 144
Abstract: Part of
a karst valley system on the southern edge of the Askrigg Block is described.
Aspects of the present underground and surface hydrology, including the
currently known sinks, risings and cave fragments, are considered in relation
to the modern topography and the underlying geology. Possible mechanisms
previously suggested for the evolution of the surface morphology are reviewed,
and a development model based on rapid incision by glacial meltwater is
presented.
