The Quaternary paleokarst of Alcubilla del Marqués (Soria)

, 1990
The paleokarst of Alcubilla del Marqués (Soria) is a portion of karstic building which has been eliminated by erosion. During karstic active stage, carbonatic (stalactite, stalagmite, cave popcorn) and siliciclastic (fluvial bars) sediments were ...

Spectral Decomposition and a Waveform Cluster to Characterize Strongly Heterogeneous Paleokarst Reservoirs in the Tarim Basin, China

, 2019
The main components of the Ordovician carbonate reservoirs in the Tahe Oilfield are paleokarst fracture-cavity paleo-channel systems formed by karstification.

Tectonic-sedimentary differentiation in Chinese cratonic basins and its control over development of large-scale carbonate reservoirs

Shiyou shiyan dizhi
The marine cratons in China are characterized by "small scale, poor tectonic stability, and strong tectonic- sedimentary differentiation." Through the basin prototype restoration and paleogeographic evolution studies of the Tarim Basin, Sichuan Basin ...

Evaluation and quantification of modern karst features as proxies for paleokarst reservoirs

, 2014
As karst features are buried into the deep subsurface and isolated from the mechanisms that formed them, they turn into paleokarst. Some karst features, such as hypogene and island karst, have a higher probability of being preserved into the deep ...

Evolution of a regionally extensive evaporite removal paleokarst complex : Mississippian Madison Group, Wyoming

, 2012
textPaleokarst systems owe their complex geometries to the interaction between the karst aquifers and the host rock being dissolved. The majority of paleokarst research to date has considered dissolution of carbonate strata (James and Choquette 1987 ...

Geoquímica de las rocas asociadas al paleokarst cretácico en la plataforma de Actopan: evolución paleohidrológica

, 2004
El paleokarst expuesto en las rocas cretácicas de la Plataforma de Actopan (Estado de Hidalgo) permite investigar, mediante la petrología y la geoquímica, la posición de las zonas vadosa y freática que propiciaron la formación del antiguo karst durante ...
