The formation of dolomite and paleokarst
of the Lower Permian series in Sichuan Basin and the relation to the Emei taphrogenesis.
The first subtype, the Permian bauxite deposit, is hosted with in the Permian carbonate rocks overlying the paleokarst
surface on the middle Permian Maokou formation (Zhang, 1999; Deng et al.
Cunningham, "Application of ground-penetrating radar, digital optical borehole images, and cores for characterization of porosity hydraulic conductivity and paleokarst
in the Biscayne aquifer, southeastern Florida, USA," Journal of applied geophysics, vol.
The Chiltan deposition is followed by emergence of the carbonate platform with the development of paleokarst
related solution breccia.
Modern caves have developed along this same Mississippian-age (330 million years ago) paleokarst
horizon in the Mooney Falls Member because groundwater readily dissolves caves as it moves more freely along this permeable horizon (Fig.
These depressions in the bedrock surface are consistent with paleokarst
features underlying Winnipeg (Baracos and Kingerski, 1998).
and associated mineralization at the Linwood mine, Scott County, Iowa.
Geology and Speleology were yet to develop as sciences, yet Lewis & Clark made significant observations of karst, pseudokarst, and paleokarst
However, for at least the last 30 years, those breccias have also been recognized as post-depositional paleokarst
features that occur on a regional scale and likely also cut formational boundaries.
carbonatite reservoirs are widely distributed in China.
These deposits overlie Upper Jurassic marine strata and are separated from them by an erosional unconformity with associated paleosols and/or paleokarst
features (Alonso and Mas 1990; Benito, 2001, Benito et al.
