VERTICAL VARIATION OF THE ORGANIC MATTER IN A COAL SEAM AND ITS ASSOCIATED SHALE IN RELATION TO HYDROCARBON GENERATION POTENTIAL IN LOW RANK COALS FROM AMAGA FORMATION, COLOMBIA

摘要

Although many studies exist about the hydrocarbon generation potential in coal seams and associated shales (1, 2, 3, 4, 5, 6, 7, 8, 9), there still exists many doubts with respect to the true importance of the associations of organic matter, oil prone and the environment in which these rocks were formed.
