摘要: Salt removal from a certain place in the subsurface can result either halokinetic salt flow or leaching (= subrosion). Seismograms British North Sea show sinkhole diameters of 1.5 km at an approximate depth km, affecting Permian and Triassic salts their overburden. Sinkholes are sediment collectors conservators. Further subsidence means good permeability sink-hole-filling sediments. A regional front leaching, called "salt slope," is 2-km wide zone local dip directed against (subsaline) dip. The age subrosion seems to be connected morphologic uplift.
