	The formation of anthracite not only takes a long time, but also requires ~~especially~~ high temperatures. The temperatures necessary for the development of anthracite coal are only possible on the borders of mountain belts. These regions are suitable because the process of building a mountain pushes sheets of rock over the layers where coal is being formed.
