Competus Rendus Geoscience. vol. 335, pp. 1059-1069. The link, "Volume 335, Issue 15, Pages 1049-1100 (December 2003)" at: http://www.sciencedirect.com/web-editions/journal/16310713 The article stated: "The newly discovered structures are located 110 km west of Djebel Arkenu and 250 km south of Kufra oasis in Libya, at coordinates N 22 degrees, 04 minutes, E 23 degrees, 45 minutes. It is a flat and hyperarid area, presenting a Cretaceous sandstone formation covered by active Aeolian deposits and Quaternary soils, ..." Their figure 1 shows the craters to be located south-southwest of the area containing Libyan Desert Glass at a distance much further from this area than either the Oasis or BP structures. The papers illustrated some very nice shatter cones and credible impact breccia and quartz grain what they call "planar fractures". I get the impression that they might have meant planar deformation features. Yours, Paul Baton Rouge, LA __________________________________ Do you Yahoo!?
