The Jurassic Hermon Mountain (Anti-Lebanon, SW Syria). Discovery of Triassic and Lias.

The lithological and micropaleontological study of the Jurassic of the Herm on Mountain (SW of Syria) furnishes new stratigraphical information on this region. The discovery of triassic foraminifera (Aulotortus spp.) at the lo wer part of Hermon sedimentary series gave evidence of the presence of Tria ssic in the Hermon area. At the same time, the discovery of the liassic for aminifer (Pseudo-cyclammina liasica HOTTINGER) in the overlapping levels, g ave evidence also of the presence of Lias. The thick basaltic layer (spilli te) which is interstratified in the sedimentary series is therefore situate d in the lower Jurassic. The Tithonian is absent in the Anti-Lebanon, due to an important stratigrap hic hiatus. This hiatus reaches the Neocomian. The biozonation by Larger Ko raminifera which is established in the Coastal Chain (Jibal As-Sahilyeh) NW of Syria, is valid in the Anti-Lebanon.
