Abstract
The archaeological record of the Western Sahara remains extremely fragmentary, with very few sites systematically excavated. The excavation at Ashash rock shelter (Zemmur region) has provided, for the first time in the region, the evidence of superimposition of two prehistoric occupations that have been radiocarbon dated to the early 9th millennium cal.BPand to the mid-7th millennium cal.BP. The Epipalaeolithic occupation is strongly marked by the standardised production of geometric microliths and points using a microburin blow technique. The Neolithic occupation of the site has yielded a few potsherds that provide the first unambiguous evidence of pottery in the Zemmur area in the mid-7th millennium cal.BP.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
