Jet is a carbon composed of pure vitrene since it was formed only from logs, specifically from gymnosperm plants that are those that have seeds but do not have flowers such as firs, pines, cedars, …

With these types of wood, a normal charcoal would be produced, but to become jet, special circumstances had to be given, those that caused oil products to infiltrate through the woody vessels of such plants, through which the sage, salts and water circulate. . In the Lower Jurassic, hydrocarbons were formed in Asturias due to high pressures, temperature and accumulation of plankton. These hydrocarbons created source rocks and permeated both marine animals and plants near the sea. With the logs, the jet was finally formed.
