Abstract

PALEOENVIRONMENTAL STUDY OF OUM ALI REGION (TÉBESSA, ALGERIA) DURING QUATERNARY, THROUGH THE STUDY OF FLUVIAL TERRACE OF KHENIGUE WADI.

Highlights

The site of Oum Ali is located to the south of the city of Tébessa, located at 250 kilometers from the Mediterranean Sea
If the kurtosis is negative, it means that the distribution is misclassified.The morphoscopic study, develop [7] is applied to the quartz grains, decarbonatation in cold conditions of the fraction between 0.5 and 0.25 mm
The study of clay mineralogy was performed by a diffractometer equipped with a copper anticathode

Summary

Introduction

The site of Oum Ali is located to the south of the city of Tébessa, located at 250 kilometers from the Mediterranean Sea. The reliefs are mixed, consisting essentially of Maastrichtian limestone along a SWNE axis, and separated by a Mio-Quaternary depression (cultivated plain of El Ma El Abiod). This structure is due to two tectonic phases that have affected the region (Atlas phase -between the upper- Miocene and lower Lutetian, and dated phase of Miocene). Level 2: localizes between -50 and - 65cm (thickness = 15 cm).It consists mainly of fine matrix (70% of total), brown olive color (dark), and rich in organic matter. Gravel and pebbles (30%), whitish calcareous nature have an irregular shape and angular edges, the degree of Defaflia Nadil et al Paleoenviromental stydu of Oum Ali region
