It can contain the minerals inertinite and vitrinite. Cannel shale is rich in hydrogen, and burns easily. Oil Shale Composition. The composition of oil shale may vary according to the depositional mechanism and setting. The composition of the original organic matter may impact the chemical composition of the embedded kerogen. Quality FactorsA typical shale is made of clay minerals (58%), quartz (28%), feldspar (6%), carbonate minerals (5%), and iron oxides (2%). A typical mudstone like shale is usually made up of 95% organic matter. The interesting fact about shale’s composition is that this percentage is usually less than 1% of its weight.Shale is a lithified mud — a sedimentary rock composed mostly of clay- and silt-sized grains. There are several ways to define shale. Some definitions are rather narrow.
