The author Discussed the rôle of plate tectonics and salt movements in terms of plate kinematics (a new term: "Halo-kinematics); defined the stratigraphic relation of the Triassic deposits with that of the Gulf of Mexico.
It is worth mentioning that the second edition of the book disclosed important geological and petroleum issues that led to the discovery of a new Triassic basin in northeast of the High Plateau of Algeria, defined its trend, and disclosed the issue of "The Missing Triassic cycle in North Algeria"; also, defined the Dome-like structure of the Hassi R 'Mel Gas Field which had been mis-interpreted as an anticlinal structure by the French geologists of "SN-REPAL, 1970", such efforts finally led to the discovery of an Oil Ring structure at the base of the Hassi R'Mel Gas field for the first time in the Middle East (only known in Asia (e.g. Iran & Russia).
It is interesting to mention that Mr. Ait Hammouda, the previous boss of the author at the northern High Plateaux was transferred together with the author to the main Dept of the Triassic Province of the southern Saharan Platform (District IV), and later the author updated several petroleum, and Stratigraphically issues, and finally discovered the oil Ring structure at the Base of the Hassi RMel gas Field.
The author prepared 15 copies which were distributed among the Algerian Ministry of Petroleum and Energy together with the Head Quarters of top officials of the State Company " Sonatrach!"
Later, the author, took the responsibility of the Canadian International Pteromata Incorporation (IPI CO) that dealt with the new Data Base Retrieval System, while he was actually checking the drilling progress of the productive wells of his own discovery of the Oil Ring structure.
