What is a shale rock

Siltstone is a sedimentary rock composed mainly of silt-sized particles. It forms where water, wind, or ice deposit silt, and the silt is then compacted and cemented into a rock. Silt accumulates in sedimentary basins throughout the world. It represents a level of current, wave, or wind energy between where sand and mud accumulate.

Oil and Natural Gas Formation. Coal, oil and natural gas typically form in sedimentary rocks. When carbon-rich organic materials, such as leaves, are deposited in stagnant water such as a bog or swamp with a low oxygen content it may not fully decay. If this happens and sediment is deposited on top, a coal bed can eventually form.Shale is the most abundant of all sedimentary rocks.
