The Reconstruction of Paleo-Environment Albo-Aptian Sediments of the Massive El Hmaima North Tebessa North-Eastern Algeria

Diab Hamida

The paper is concerned with the studying of Albo-Aptian across North Africa to focused on sedimentological, tectonic and paleontological study of Albo-Aptian formations massive El Hmaima-North of Algeria. A systematic study was then initiated consisting of the sampling in a washing furniture samples of some Albo-Aptian rock units , and a careful sorting of microfossils and minerals under the lens of binocular microscope. Albo-Aptian is characterized by carbonate deposits rich in organic matter levels. This interval is marked by a large marine transgression typically connected to a eustatic rise in second order by tectonic events related to the opening of the western part of the Mediterranean sea and/where the rifting of the central Atlantic and conditions paleogeographic. Mineralogically, the studied area are contain the important industries minerals such as; Calcium carbonate, Gypsum, Ferruginous nodules, pyrite, Quartz and clay minerals.
