The rocks in this area consist mainly of Neogene sedimentary rocks and Quaternary sediments of various origins. The Neogene sedimentary rocks, the basement of the area, consist of gypsum with fine-grained acidic tuff intercalations. The Quaternary sediments mainly made up of well-stratified silts, sands and pebbles overlie the Neogene sedimentary rocks with unconformity. The sediments forming several terraces along the River Euphrates can be stratigraphically divided into the following two parts, Lower part composed largely of alternating beds of gray fine to course sands and granule to boulder layers, Upper part composed mainly of milky- to yellowish- white silts and sands with minor intercalations of granule to pebble layers. The granules, pebbles and boulders, clast-supported, well sorted, generally include well-rounded flatten clasts of red chert, granites, lyorite, basalt and fine (microcryptic) siliceous rocks in a matrix of middle grained sands. The deposits are generally well stratified with various kinds of sedimentary structures such as grading, cross-bedding and clast imbrications. East-going paleocurrent is supposed by the sedimentary structures. Quaternary alkaline basalts exposed in some places unconformably overlie the Neogene sedimentary rocks.}, pages = {1--11}, title = {シリア,テル・ガーネム・アル・アリ遺跡周辺の地質}, volume = {26}, year = {2010} }
