Speleogenesis in Comal County, Texas
… useful in identifying the factors involved in speleogenesis when used in conjunction with areal maps of the aforementioned controls. Effluent caves in the lower Glen Rose Formation are localized within a massive, fossiliferous aquifer and oriented generally down-dip, thus substantiating …

Interpretations of Paleoclimate and Speleogenesis from Speleothems in Donnehue's Cave, Indiana
A detailed understanding of the climate of the Pleistocene (1,800,000 years ago to 10,000 years ago) is crucial for constructing predictive models of future climate trends. Researchers studying past climate (paleoclimate) records from different parts of the world are beginning to piece together an …

Speleogenesis of Critchfield Bat Caves and Associated Hydrogeology of the Northern Edwards Aquifer, Williamson County, Texas
… were analyzed and mapped as an assessment of the speleogenesis of specific features. Stratigraphic analyses found there are eight facies total on Critchfield Ranch ranging from low-energy depositional environments with the mudstones and wackestones to high-energy depositional environments with the …

Speleogenesis and Delineation of Megaporosity and Karst Geohazards Through Geologic Cave Mapping and LiDAR Analyses Associated with Infrastructure in Culberson County, Texas
<p>The Gypsum Plain region of the Delaware Basin hosts approximately 1800 km<sup>2</sup> of the Castile Formation outcrop. A myriad of karstic developments from closed sinkholes to large multi-kilometer cave systems have been documented within the region. Karst studies on the distribution and …

Using 34-S as a Tracer of Dissolved Sulfur Species from Springs to Cave Sulfate Deposits in the Cerna Valley, Romania
… and exotic morphologic features that suggest speleogenesis by sulfuric acid. 𝛅34S of the sulfates relates to sulfide isotopic values from the springs, showing that the dissolved sulfide (upon oxidation) forms sulfuric acid s that reacts with limestone to produce sulfate minerals. A wide range …

Cave Development in Strata of Ordovician-and Silurian-Devonian-Age in Highland County, Virginia
… how geologic structures and processes control speleogenesis, or cave development, in the county. Solutional caves in Highland County are found in Ordovician limestones and dolostones and in Silurian- to Devonian-age limestones. Despite the lithologic and structural differences between the …

Investigations of rapid groundwater flow and karst in the Chalk
… karst development resembling the early stages of speleogenesis.

Speleogenetic Evolution and Geological Remote Sensing of the Gypsum Plain, Eddy County, New Mexico
<p>Permian evaporites of the Gypsum Plain region of the Delaware Basin host extensive karst phenomena, as well as unique diagenetic alterations of host strata. Because of the complex, poorly understood hydrogeologic system, little has been established concerning the relation and evolution of the …
