ABSTRACT

This paper reviews what intracratonic basins are and categorized it stating clearly the types and with the case study of the north Saharan intracratonic basins. The historical trend in North Africa is Early Precambrian to Phanerozoic Characterized by at least 7 big phases of tectonic activity: Pan-African organic, intracambrian expansion, varying scale from Cambrian to Carboniferous and Compression, mainly intraplate Late Carboniferous 'hercynian,' late Triassic Early Jurassic and Early Cretaceous Rifting, Late cretaceous - tertiary 'Alpine' compression and rifting in Oligo-Miocene. North-western areas of North Africa are heavily impacted by plate collisions during the hercynian and Alpine ages, not several of them. The region was subjected to only subtle processes involving repeated interpolate processes transpersonal and trans tensional major fault reactivation. Late Continental Carboniferous Collision between Gondwana and Laurasia contributed to Elevating and thrusting in northwestern North Africa and folding and reversing in intra-plate neighborhood. Deformation severity decreased to the east, In the Northwest, Hercynian folding and erosion replaced by subtle, low-angle erosion. Further south and east, discrepancies and disconformities. This geological structure is the product of the accretion of Archean and Proterozoic terranes accumulated from previous orogeny (e.g., Pan-African orogeny 900–520Ma). The sedimentary infilling trend and the existence of deformation derive therefore from recurrent gradual Paleozoic reactivation of Precambrian terrines bounded by sub vertical lithospheric fault systems. A succession of Paleozoic geodynamic occurrences (i.e., far-field organic chain, glaciation), leads to intermittent cycles of tectonic quiescence and low-rate subsidence acceleration consistent with expansion and local inversion tectonics. Ultimately, this polyphase evolution created a highly interconnected and interconnected network superimposed Paleozoic and Precambrian basins isolated by long-lived, stable basins . The petroleum potential of these basins varies according to their location. Different tectonic, thermal and sedimentary developments and the complexity of built styles. These factors combine to make conditions particularly favorable for the production and storage of hydrocarbons in the eastern Algerian basins and to the west of Libya.
