“…Topographic sheets of various scales and geologic maps of Hunting (1979), Warrak (1987) and Whittle & Alsharhan (1994) were used in combination with Landsat TM and SPOT images to study the geology of the greater Al Ain area and the distribution of the various sand dune fields. Sampling of the dune fields was carried out along the roads: Al Ain } Al Wagan, Al Ain } Abu Dhabi, Bu Samra } Sweihan } Al Hayer, Al Ain } Dubai, and Al Hayer } Al Madam (Fig.…”

“…Discriminating characteristics established by these analysis (morphology, mean size, roughness, sedimentary structures, textural and mineralogical composition) must be contextualized with previous knowledge of outcrop deposition (Tricart & Vonfelt 1955;Sittler & Demangeon 1963) because the palaeoenvironmental conditions of the deposits from which it was formed determines chert's characteristics and chemical components (Whittle & Alsharhan 1993;Murray 1994;Dasgupta et al 1999;Umeda 2003;Becker & Bechstädt 2006).…”

Abstract:We present the results of prospecting in the NE of the Iberian Peninsula, with the aim of identifying the siliceous sources potentially used by the populations that occupied the marginal basins of the Ebro depression during the Middle and Upper Palaeolithic.We intend to define the main characteristics of the cherts in the region studied, taking into account the palaeoenvironment in which silicifications are mainly formed, and the premise that siliceous rocks acquire the attributes of enclosing rocks.The cherts studied are the products of early diagenesis by replacement of carbonate and evaporite sediments. Petrological analyses show that they are made up of microquartz, with high proportion of fibrous forms silica, carbonates, ferric oxides and evaporite relicts. In the future, these characteristics will be useful for ascribing archaeological materials in both geological and geographical terms.Keywords: lithic raw materials; chert characterisation; Ebro Basin; depositional models Abstract:Presentamos los resultados de las prospecciones realizadas en el NE de la Península Ibérica, con el objetivo de localizar las áreas fuente silíceas potenciales para la captación de los paleo-pobladores que ocuparon las cuencas marginales de la depresión del Ebro durante el Paleolítico medio y superior.Definiremos los principales caracteres de los sílex de la región estudiada, teniendo en cuenta el paleoambiente de los afloramientos y con la premisa que los sílex adquieren los atributos de la roca encajante.Los sílex estudiados son producto de una diagénesis temprana por reemplazamiento de sedimentos carbonatados y evaporíticos. Los análisis petrológicos muestran que estos están formados por microcuarzo, con altas proporciones de sílice fibrosa, carbonatos, óxidos de hierro y relictos evaporíticos. Estos caracteres serán útiles para la posterior adscripción geológica y geográfica de los conjuntos arqueológicos.

“…Arab Emirates (UAE): the Rus Formation is subdivided into two lithologic units(Whittle and Alsharhan 1994): l-the lower fossiliferous dolomitic argillaceous limestone unit (20 m) and 2-the upper limestone unit (164 m). The formation is dated approximately to the Early Eocene Ypresian time(Whittle and Alsharhan 1994; Alsharhan and Nairn 1995).…”

“…The formation is dated approximately to the Early Eocene Ypresian time(Whittle and Alsharhan 1994; Alsharhan and Nairn 1995). Based on its regional stratigraphic position and the similarity of the faunal content in eastern Arabia, the Rus Formation in UAE should be assigned to the early Middle Eocene (Lutetian).Oman: the Rus Formation has a mixed facies characterized by cherty chalky, argillaceous limestones (southern surface sections) and anhydritic, dolomitic limestone (northern subsurface sections;Fig.…”
