Asymmetric slip planes within a shear zone, echelon arrangements of extension fractures and those of shear fractures, and the two types of "cymoid loop": adjoining two shear fractures bridged by extension fractures and those bridged by shear fractures are common also for ore veins and vein systems. By estimating the stress orientation and the dependence of the fracturing mode on confining pressure, the distribution of ore bodies, including the depth and pitch of cymoid loops, can be effectively predicted.
