“…This and the likely association of the deposits with either the Late Miocene orogeny or the Neogene volcanism suggest that hydrothermal karstification, which has been reported at other MVT deposits elsewhere (e.g. Fowler, ; Bouch et al ., ; Gutzmer, ), was an important mechanism, rather than replacement, for generating mainly pre‐mineralization porosity in the Triassic dolostones (cf. Nicolini, ; Rouvier, ; Mansouri, ; Rouvier et al ., ; Slim‐Shimi & Tlig, ).…”

“…Since the lateral permeability is always higher than the vertical permeability in a sedimentary pile, basin fluids driven by compaction and heat convection mainly migrate laterally along aquifers with higher permeability (Bjrlykke, 1993(Bjrlykke, , 1994Deming, 1994). These overpressured zones normally have a high geothermal gradient (Fowler, 1994). Thus, they are unimportant to the effective accumulation of ore substances.…”

“…Fluids transferred in this way can gradually lose their potential and kinetic energy through reequilibrium in heat and materials with wall rocks during their continuous, slow, and long-distance migration. Such a rapid and episodic fluid flow could sustain the energy and material brought from the deep part (Fowler, 1994). We think that the basin fluids, which might be significant for solution, transportation and precipitation of metal components, are mainly overpressured hydrothermal fluids accumulated in undercompacted zones of the basins with rapid sedimentation and subsidence under an extensional tectonic setting.…”
