Determination of the age of relief and denudation rates of the south-west part of the Inner Range of the Mountainous Crimea from karstological and speleological data, 2011, Klimchouk A. B. , Tymokhina E. I. , Amelichev G. M. , Dublyansky Yu. V. , Staubwasser M.

U/Th dating of calcite speleotems of karst cavities in the south-west part of the Inner Range of the Mountainous Crimea permitted to establish age constrains for the period of termination of the hypogenic development of karst systems and for geomorphologic settings corresponding to incipient and mature expression of the Paleocene segment of the range in relief. This also allowed evaluating rates of denudational deepening of the southern longitudinal depression (SLD). It is found that the main elements of the relief in this belt of the fore-mountains had been formed during the second half of Middle Pleistocene, which changes substantially a concept of the age of the relief for the region toward younger values. The rate of denudational deepening of the depression is determined to be 1.36 (0,08) mm/a. For the time intervals of the second half of Middle Pleistocene (250 130 ka) and Late Pleistocene Holocene (last 130 ka) the rates are, respectively, 0.9 and 1.8 mm/a, although determined with much higher error (0,3 mm/a). The increase in the rates of the denudational deepening of the SLD during Late Pleistocene Holocene indicates the respective increase in the uplift rates


HYPOGENE SPELEOGENESIS AND SPELEOTHEMS OF SIMA DE LA HIGUERA CAVE (MURCIA, SOUTH-EASTERN SPAIN), 2013, Gá, Zquez Fernando Calaforra José, Marí, A

 

Sima de la Higuera Cave (Pliego, south-eastern Spain) has been recently adapted for speleological use. Nevertheless, knowledge of the hypogenic origin of this cavity is still quite limited. The peculiar genetic mechanisms could provide added value if the cave is exploited for speleotourism. By studying geomorphological features and speleothem characteristics, it has been possible to deduce the predominant speleogenetic mechanism (whether hypogenic or epigenic) that controlled the evolution of this cave. The hypogenic mechanism that gave rise to this cavity was associated with upflow of CO2-rich hydrothermal fluid from depth, and was unconnected to meteoric water seepage. In this paper we describe some of the geomorphological evidence and unusual speleothems in Sima de la Higuera Cave. Large scallops are found on the upper level (-74 m); these are related to the mechanism of hypogenic speleogenesis and generally indicate the direction of ascending flow. There are also corrosion crusts made of micritic calcite. In addition, bubble trails related to bubbles of rising CO2 have been identified. Centimetric calcite spar speleothems frequently fill fractures in the host rock. Other typical hypogenic speleothems occur in this cave, including calcite raft cones, folia, cave clouds, tower coral and calcite raft deposits, all suggesting the influence of thermal water during the cave’s formation. Furthermore, the first reported occurrence of calcite raft double-tower cones has been described in this cave; their origin is linked to water table oscillations in Paradise Chamber (-82 m). At the deepest level (-110 m), Mn-Fe oxyhydroxides occur as a black coating totally covering the cave walls, usually over subaerial “boxwork” formations. The wide variety of speleothems unconnected to meteoric water seepage make Sima de la Higuera Cave one of the most unusual hypogenic caves in Spain.
