[1] The early stage of hypogene karstification is investigated using a coupled thermohydrochemical model mountain hydrologic system, in which water enters along table and descends to significant depth (∼1 km) before ascending through central high-permeability fracture. incorporates reactive alteration driven by dissolution/precipitation limestone carbonic acid due both temperature- pressure-dependent solubility, kinetics. Simulations were carried out for homogeneous heterogeneous initial...
Precipitation and dissolution reactions within fractures alter apertures, which in turn affects their flow transport properties. Different aperture alteration patterns occur different reaction regimes, they are also influenced by preferential resulting from spatial variations the aperture. We consider of variable‐aperture gradient where fluids chemical equilibrium with a mineral everywhere but precipitation driven solubility gradients associated temperature variations. The field is defined...
Upward flow through vertical fractures in limestone formations under a geothermal gradient favors dissolution and permeability growth. We investigate the transition from conductive forced convective regimes to instability buoyant convection as result of The onset time for roll height at depend on initial aperture driving pressure. A modified Rayleigh number criterion is proposed, which provides unified interpretation across wide range Interaction between alteration leads narrow upward paths...
