“…Mechanical compaction and also diagenesis over geological timescales further complicates the problem as permeability reduction up to 3 orders of magnitude can occur as a result of mineral precipitation Schechte and Gidley, 1969). These competing processes may result in a fault with low permeability surrounded by a highly permeable damaged zone and fluid channeling along the fault (Barnicoat et al, 2009;Evans et al, 1997). In other words, the permeability of the faulting zone rock mass can be extremely anisotropic.…”

“…A SEDEX (sedimentary exhalative) típusú ércesedésre dolgozták ki azt a termális konvekciós áramlásos modellt, ahol extenziós félárok szerkezetben mátrix porozitással rendelkező üledékek alakultak át, illetve esetenként dolomi tosodtak a medencét meghatározó normál vető mentén feláram ló fluidum hatására (BARNICOAT et al 2009). A reo lógiai jellegeknek van szerepe abban, hogy a litifikált aljzat kőzeteiben vető mentén feláramló hidrotermás fluidum a hőmérséklet-különbségből adódó felhajtó erő miatt felfelé és oldal irányba szétáramlik a cementálatlan, félig konszo lidált medenceüledékben -mivel itt törés nem jön létre (BJØRLYKKE 1994(BJØRLYKKE , 2010.…”

“…This assumption is reasonable, because faults in porous sediments often act as low permeability barriers rather than pathways for fluid flow (e.g. Barnicoat et al 2009). The known mineralisation is hosted by dolomitic and organicrich siltstones of the HYC Pyritic Shale Member in the lower BCF.…”
