Is karstification a giagenesis event
WitrynaTo model the development of karst channels from primary fissures in limestone, a computer simulation of solutional widening of a fracture by calcite agressive water is proposed. The parameters defining the problem are the initial width a0 of the fracture, its length l, and the hydraulic gradient i driving water through it. The … WitrynaIn all these Karstification processes all three types genetic phase (initial , main and late phase or fossil karst features . They are easily distinguishable in relatively younger …

Did you know?
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. … WitrynaPlural ofkarstification.
