    Shale densities vary according to depth. The range of shale density may vary from 1.8 gm/cc near the surface to 2.60 gm/cc at 12,000 feet (US Gulf Coast). Bulk density in a laminated shaly sand is based on; shale density, matrix density, and fluid density. Laminated shale-sands are defined as having laminae that do not exceed .5 inch thickness.

    The pelletal material exiting the kiln is called “clinker. ” Gypsum is added, and the clinker-gypsum mixture is finely ground into Portland cement. The burning of limestone in the cement-making process liberates carbon dioxide gas (formula CO2). Limestone is used in the manufacture of three kinds of lime that have a wide range of uses.

    Description. The Marcellus consists predominantly of black shale and a few limestone beds and concentrations of iron pyrite (Fe S 2) and siderite (FeCO 3). Like most shales, it tends to split easily along the bedding plane, a property known as fissility. Lighter colored shales in the upper portion of the formation tend to split into small thin-edged fragments after exposure.
