Desert sedimentary environments K. W. Glennie

About one fifth of the world s land surface is desert but, contrary to the popular Lawrence of Arabia concept, only oqe fifth of the desert areas is covered with sand (HOLMES1,9 65, p.760; see also Fig.1). Fossil desert sediments (mostly dune sands) have been recognised in various periods from the Cambrian to the present. The desert origin of many of such formations has been in dispute, however, for various reasons; sometimes it was because authors were discussing sediments of the same age but of different facies and locations, the one in a desert facies, and the other closely associated with marine fossils (McKEE, 1962, p.558). In other cases it is apparent that the authors did not know what factors were significant in deciding between desert and non-desert sediments, or the differences Воспроизведено в оригинальной авторской орфографии издания 1970 года (издательство "Elsevier").
