How is oil deposits formed underground?

The fossil remains, the dead and decayed matter is the main source for the oil and mineral deposits underground. All the dead plants and animals buried underground go through decomposition by the bacteria and microorganisms present deep inside the ground. All these decomposed and left over remains combine to form the oil deposits. As more and more sediments gets deposited underground the temperature and pressure causes breakdown in them. Protein, lignin and cellulose break down instantly into amino acids and sugars. The heat catalyses the reaction. Through exposure to air and water it oxidises. A small proportion of this organic
