Chemical and Geochemical Characteristics of the Moroccan Rif Bituminous Rocks (original) (raw)

Abstract

Morocco has been classified into the seventh position according to the recent estimation of the world's reserves of oil shale. Three principle deposits are located in Timahdit, Tarfaya and in Rif regions. The present work concerns the physico-chemical and geochemical study of bituminous rocks of northern Morocco (Rif). Samples from four different sites named: Tangier (TA), Tetouan (TE), Bab Taza (BT) and Arba Ayach (AA) were analyzed by different analytical methods, pyrolysis, thermal, mineralogical and molecular techniques. The Rock-Eval results confirmed the thermal maturation for the sample AA. The content of total organic carbon (TOC) vary from poor to excellent (0.45% to 4.47%), the value of general potential hydrocarbon production (GP) ranged from 0.49 to 13.1 (mgHC/g rock) and the value of the hydrogen index (HI) vary from 37 to 282 (mgHC/gTOC), suggesting types II, III and IV of kerogen. Thermal analysis revealed a total organic content ranging from 4.77 to 7.53%. Elemen...
