CommentsCurkin (1962) interprets dolomite, limestone, shale, dolomitic sandstone and dolomitic siltstone of the Saturday Mountain Fm as transitional between the turbiditic argillites of the Phi Kappa Fm, ot the western eugeosynclinal (or continental-slope) facies and the Fish Haven Dolomite of the eastern miogeosynclinal (or continental-shelf) facies.
