Fine-grained sedimentary rocks are classified into three types, organic-lean, organic-bearing, organic- rich by taking TOC values of 0.5% and 2.0% as dividing points. The parallel triangle diagram of 4-component classification system by Pettijohn [26] was employed to include TOC in the nomenclature (Fig. 3). 3.3.2.Sedimentary rocks are formed by the deposition and subsequent cementation of materials on Earth’s surface and within bodies of water. Examples of sedimentary rocks include chalk, limestone, shale, quartz- lithic sandstone, conglomerate, chert, carbonaceous mudstone, and coal seams. Forming more than nine-tenths of Earth’s surface ... ….

The term siliciclastic refers to sediments composed mostly of silicate minerals. The most common sedimentary rocks - including shale, sandstone, and conglomerate - form from siliciclastic sediments. Other kinds of sedimentary rocks consist of carbonates (in limestones), iron oxides and hydroxides (such as hematite or goethite in iron formation), or other minerals.8.
