Abstract:

Three types of sedimentation occur during the formation of oil shales, either in marine locations, in lacustrine locations and on the continent. The Timahdit oil shale deposit is located in the Atlas Mountains,In this work we counted four reasons to confirm that this deposit called TImahdit is a lacustrine deposit. The techniques used during this study are dispersive X-ray diffraction, infrared spectroscopy, thermogravimetry (DTG) and atomic absorption.X-ray diffraction in dispersive allowed us to identify qualitatively and in an elementary way the elements, for example the element chlorine.Infrared spectroscopy allowed us to follow the two compounds of the oil shales, aliphatic hydrocarbons and aromatic hydrocarbons and to relate the two compounds in mass.Thermogravimetry (DTG) allowed us to compare the reactivity of the Timahdit deposit with that of the Tarfaya marine deposit.Atomic adsorption allowed us to quantitatively follow the sodium element and to make a comparison with the Tarfaya marine deposit which is located in the Atlantic Ocean.
