The crack is now sealed, and no fluid can flow through the crack any more. The crack-seal cycle can occur once, with a wide open crack forming, which is then sealed by crystals that grow from the wall rock into the fluid-filled space. Normally, the crack-seal cycle is repeated many times. The resulting veins are then often called crack-seal veins.
