Karst reservoirs are important exploration targets in marine carbonates of hydrocarbon-
bearing basins around the world. In the Tarim Basin of northwest China, four types of …

Whereas most karstic caves worldwide are formed by carbonic acid, a small but significant
number of sub-surface cavities are the product of sulfuric acid speleogenesis (SAS). In the …

The state of cave research in Austria is outlined from the geological and zoological
perspective. Geologic sections include the setting of karst regions, tectonic and …

Alteration of conventional carbonate stable isotopes (δ18O, δ13C) in cave walls has been
shown to be a useful tool to identify cave formation driven by deep-seated processes, ie …

An analytical line for stable isotope analyses of water recovered from fluid inclusions in
minerals was built and successfully tested. The line is based on the principle of continuous …

Hypogene karst caves, formed independently of surface processes, have garnered
increasing attention in recent decades, revealing a wider distribution than previously …

Despite its small size Austria is home to about 16,000 caves. The vast majority is epigene in
origin and occurs in uplifted karst plateaus. Only about hundred caves of hypogene origin …

Thermal waters moving through soluble rock may create voids ranging in sizes from
enlarged porosity and cavernosity to extensive two-and three-dimensional cave systems …

Hypogene speleogenesis involves the formation of solution-enlarged permeability structures
driven by ascending water acquiring its acidity from deep-seated sources. This process …

Although it is commonly perceived that isotopic alteration of carbonate rock is suppressed at
low temperatures (below ca. 80–100° C), this study demonstrates that alteration halos do …
