The Early and Middle Holocene Lithic Industries of Ifri n’Etsedda (Eastern Rif, Morocco)

Archaeological research has been carried out in the Eastern Rif (Morocco) since 1995 by a collaborative Moroccan-German research team. A major topic of the project is the transition from hunting-gathering to food production and related cultural developments. Innovations such as pottery and domesticated species appeared around 7.6 ka calBP. The cultivation of cereals and pulses is evident at that time. Two of the most important sites in the area are Ifri Oudadane and Ifri n’Etsedda. Both provide Epipaleolithic as well as Neolithic deposits. While innovative technologies such as pottery production and cultivation indicate external influences, lithic artifacts demonstrate local technological and behavioral traditions. Therefore, the study of lithic industries is crucial to understanding the nature of cultural continuity and discontinuity between the hunting-gathering and agricultural populations in the Eastern Rif. Ifri n’Etsedda provides two distinct Epipaleolithic deposits and thus offers the opportunity to study possible changes throughout the Epipalaeolithic and relationship to the later Early Neolithic (ENC). In combination with the earlier phases of Early Neolithic assemblages (ENA, ENB) at Ifri Oudadane, we are now in a better position to understand the development of early-to-mid Holocene lithic technology in the Eastern Rif. We show that the lithic record of Ifri n’Etsedda does not indicate any significant change in raw material supply, blank production, and tool distribution from the Early Epipaleolithic to the Early Neolithic B. Therefore, we argue for behavioral continuity from the Epipaleolithic to the Neolithic period. In contrast, the assemblages of the Early Neolithic C show changes in lithic technology

Site formation and chronology of the new Paleolithic site Sima de Las Palomas de Teba, southern Spain

The newly identified Paleolithic site Sima de Las Palomas de Teba hosts an almost seven -m-thick sediment profile investigated here to elucidate the rock shelter's chronostratigraphy and formation processes. At its base, the sediment sequence contains rich archeological deposits recording intensive occupation by Neanderthals. Luminescence provides a terminus ante quem of 39.4 ± 2.6 ka or 44.9 ± 4.1 ka (OSL) and 51.4 ± 8.4 ka (TL). This occupation ended with a rockfall event followed by accumulation of archeologically sterile sediments. These were covered by sediments containing few Middle Paleolithic artifacts, which either indicate ephemeral occupation by Neanderthals or reworking as suggested by micromorphological features. Above this unit, scattered lithic artifacts of undiagnostic character may represent undefined Paleolithic occupations. Sediment burialagesbetweenabout23.0±1.5ka(OSL)and40.5±3.4ka(pIRIR)provideanUpperPaleolithicchronology for sediments deposited above the rockfall. Finally, a dung-bearing Holocene layer in the upper most part of the sequence contains a fragment of a human mandible dated to 4032 ± 39 14C yr BP. Overall, the sequence represents an important new site for studying the end of Neanderthal occupation in southern Spain

Intensity noise self-regulated solid-state laser at 1.5μ{\mu}m using an ASHG based Buffer Reservoir

An absorption mechanism based on second-harmonic generation (ASHG) is successfully implemented as a buffer reservoir in a solid-state Er,Yb:Glass laser emitting at telecom wavelength. We show that a slight ASHG rate conversion of 0.016% using a BBO crystal enables to cancel out the excess intensity noise at the relaxation oscillation frequency, i.e. 35 dB reduction, as well as to cancel the amplified spontaneous emission beating at the free spectral range resonances of the laser lying in the GHz range.Comment: 6 pages, 5 figure
