...Olanrewaju Aboaba; Christopher Liner Abstract Paleokarst regions worldwide are repositories for hydrocarbons, mineral deposits, and groundwater. Time structure maps were generated for the Ordovician Viola Limestone, Mississippian Caney Shale, and Pennsylvanian Jefferson Sandstone and Wapanucka...

... achieved more than 80% success in exploration based upon bright spots ( Zeng et al. 2011 a ), which typically indicate karst cave-, pore-, fracture–cave-, and fracture-related reservoirs ( Han et al. 2007 ). The infilling of paleokarst caves and their collapse during subsequent burial could cause...

... extensive porosity ( Field, 1999 ; Wright et al., 2014 ). As such, karsts and paleokarsts represent key plays within carbonate-hosted reservoirs worldwide, namely, in hydrocarbon fields in China ( Han et al., 1998 ; Liu et al., 2004 ), Texas ( Loucks and Anderson, 1985 ; Kerans, 1988 ), Thailand ( Heward...

..., which are ~2000 km to the east. There is also a provenance signature from the rising Ancestral Rocky Mountains. The evidence suggests dust trapping on land surfaces by paleokarst topography, moisture, and vegetation. Weak paleosols in the Molas Formation suggest relatively rapid rates of dust...

... as a series of incised paleokarst valleys, 100–500 m wide and ∼ 50 m deep along an irregular paleocoastline ( Desrochers 2006 ). Where examined at Brick River the surface is not planar but markedly concave and passes gradually basinward into a conformable erosional surface. The surface outboard is smooth...

... Lessini Mountains which partially emerged. In the Torricelle area, ochres are believed to be the insoluble residuals of subaerial weathering of upper-Priabonian marly limestones. The exploration of paleokarst cavities and of the surrounding area has led to the discovery of terrigenous-calcarenitic layers...
