Summary[edit]
| Description |
Français : Représentation du processus de houillification = transformation de couches plus ou moins épaisses de débris végétaux (en vert à gauche) en charbon (houille, en noir à droite) , au cours des âges géologiques. C’est un processus très lent (millions à centaines de millions d’années) . Les charbons les plus denses et riches en carbone sont dits de haut-rang (ce sont les plus anciens). Les charbons récents sont dits de bas rang. English: Representation of the process of coalification = transformation of more or less thick layer of plant debris (green left) in coal (coal black right) during geological ages. This is a very slow process (millions of years or hundreds of millions of years). The densest coal and carbon-rich are called high-ranking (they are older). Recent coals are said to be low rank. |
