Shale description

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO 3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.

Description Fragments below exposure of fissile Marcellus black shale at Marcellus, N.Y. 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.A shale formation is a sedimentary rock composed of fine-grained detrital mineral (silt-size particles of quartz and calcite) and flakes of clay and it is characterised by the presence of about 1% to over 20% of Total Organic Carbon content (TOC).
