Rachgoun 2: Geomorphological and Lithostratigraphic Framework

Summary: Half a century after the work of prehistorian G. Camps on “Iberomaurusian” site Rachgoun, located northwest coast Algeria, nothing has come to confirm, supplement or revisit conclusions this author, which still remain in force. In 2017, interest deposit was revived, with view relaunching prehistoric research Algerian north-west (Oran). contribution, we have approached subject, from geosystemic point view, under angle geomorphology and Quaternary geology, offer us guarantees access appropriate readings Rachgoun's kjokkennmodding. Two morpho-sedimentary groups were identified (q1 4c qD) their connection classification frameworks force, carried out. They are expression Sicilian-Tyrrhenian geography, ended development rhythmic phenomenon "sandstone-red silt dunes", witness variations sea level, relation glacio- eustatism neotectonics. Thus, current landscape Rachgoun region is recent established Tyrrhenian, new cycle, will lead configuration relief. chronostratigraphic framework, previously qualified as Iberomaurusian (epipaleolithic), occupies first part Holocene (early Rharbien), dated C14 9430 9490 years BP. A chronological position commands archaeological reading.
