Analysis of the evolution and rank distribution of coals from the Oyon basin (Upper Jurassic) of Peru

The Oyon Coal Basin (Upper Jurassic) is located in the central part of Peru and it is centered around two nuclei of very faulted and strongly tectonized anticlines. The middleupper part of the Oyon Formation which is representative of the sedimentary registry of this Basin contains the coal producti...
