Glacially-Influenced Sediment Cycles in the Lime Creek Karst, Eagle County, Colorado,eomorphology. These maps were used to relate cave sediments to surface deposits and to assemble a depositional history of the caves. Speleogenesis and karst development was strongly controlled by the advances and retreats of Pleistocene glaciers and advances of Holocene rock glaciers. Cave developme

,Cave Sediments and Denuded Caverns in the Laški Ravnik, Classical Karst of Slovenia,ical parts of the karst surface. This paper sets out to demonstrate that detailed, systematic, field mapping of denuded cave features (“surface caving”) not only increases the number of caves known in a given area, but also yields a better insight into the spatial organization of cave systems, by ca

Paleoclimate Records from Speleothems in Limestone Caves,one (speleothems). Variations in trace element concentration, isotopic composition, and trace organic compounds incorporated into the calcite provide a highly detailed record that should correlate with temperature and rainfall variations at the land surface. Growth rates of calcite layers are highly

Uranium-Series Dating of Speleothems: Current Techniques, Limits, & Applications,sible if the initial concentrations of .Th and .Pa are well constrained and if the system has remained closed to post-depositional exchange of uranium, thorium, and protactinium. An estimate of the plausible range of initial .Th/.xh values combined with the measured .Th/.U ratio reveal, to first ord

Paleoclimate Information from Speleothems: The Present as a Guide to the Past,lagmites, and flowstones which are a ubiquitous feature of caves worldwide. Variations in the.O/.O and .C/.C ratios in calcite speleothems can provide important information about terrestrial paleoclimate, if deposition occurred under equilibrium conditions because (i) they contain a well-defined int

Influence of Depositional Environment on Devils Hole Calcite Morphology and Petrology,hat contain at least two different paleoclimate records. Below water table deposits contain a 560,000 year paleoclimate isotopic record (Winograd et al., 1992), while above water table deposits record 120,000 years of changing water table elevation (Szabo et al., 1994). The different depositional en
