ABSTRACT:. Many gold and base metals deposits in Western Australia are hosted in anisotropic rock masses. These may comprise bedded siltstones, sandstone and shales or foliated mafic and ultra-mafic rocks. When bedding or foliation are unfavorably oriented, slope instability mechanisms generally involve sliding along these anisotropy …
