Before the compression tests, all shale samples were painted with white and black paintings to make sure that the lateral surface can be recognized by ARAMIS digital cameras. All the UCS tests were conducted in a Shimadzu AG 9300 kN compression machine with a loading rate of mm/min.

The Marcellus Formation is a black shale that may contain limestone beds and concentrations of iron pyrite (Fe S 2) and siderite (FeCO 3). Its sedimentary structure, or bedding, is moderately well developed. Like most shales, it tends to split easily along the bedding plane, a property known as fissility.

Many black shales resemble bone but can be differentiated from it by density and the color of the powdered rock. Bone is considerably less dense than shale and, when scratched with a knife, powdered bone is orange brown or black but shale is gray.

Although shale may occur in a variety of colors, shale in Vermont is usually dark grey or black. Where it occurs as thinly laminated strata, shale is often mistaken for slate (a metamorphic relative described below). This black shale is both carbonaceous (contains carbon, C) and calcareous (contains calcium carbonate, CaCO3).

The relative hardness of minerals is determined according to Mohs Scale, named after the German mineralogist, Friedrich Mohs (), who devised it in 1812. In the original Mohs Scale, ten minerals were arranged in order of increasing hardness and were assigned the numbers one to ten.

Paragneiss in most cases is thought to be the end product of metamorphism of a pelitic (clayrich) sedimentary rock (shale, argillite, claystone, etc.) that metamorphosed first into slate, then became phyllite, schist, and finally gneiss. Still deeper burial or more intense heating may result in migmatization and finally complete melting of gneiss.
shale Finegrained, fissile, sedimentary rock composed of claysized and siltsized particles of unspecified mineral composition. The noun may be qualified by an adjective ( black shale, paper shale, and oil shale).
