Shale consists of at least 30 percent clay, with varying amounts of quartz, feldspar, carbonates, iron oxides, and organic matter. Oil shale or bituminous also contains kerogen, a mixture of hydrocarbons from deceased plants and animals. Shale is classified based on its mineral content.Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as " mudstones ." Shale is distinguished from other mudstones because it is fissile and laminated.Phyllite Rock. Phyllite is a foliated metamorphic rock that is primarily composed of quartz, mica, chlorite, and sericite. The Phyllite rock is formed by the slate that is further metamorphosed so that the coarse-grained mica attain a preferred accommodation. The word Phyllite is derived from the Greek phyllon meaning “ leaf”.

Composition of Phyllite. Phyllite is composed mainly of tiny grains of mica minerals such as muscovite, or sericite. Fine-grained quartz and feldspar are often abundant in phyllite. These mineral grains are usually smaller than what can be easily seen with the unaided eye. They form through the low-grade metamorphic transformation of clay minerals.

Hence, shale tends to be weak, requiring support for bearing loads. In addition, depending upon the type of clay minerals present, shale may present shrink/swell problems (smectite and chlorite minerals), or squeeze/deformation problems (kaolinite and chlorite minerals).
