..., the underground karst system gradually developed, the whole drainage system continuously converged from north to south, and had a significant impact on karst development ( Fig. 11 c ). Reservoirs of this stage that are represented seismically by bright spots are mainly paleokarst caves. At the end...

..., 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...

... surface ( Figs. 3 , 5.3 ) cuts down as much as 50 m into older strata. This and other similar features are interpreted 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...

... 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...
