Abstract
KRAUS and Wagner's “Elsass” is the first in number of a series of monographs on the geology of some chief fields of the War. It shows the extent to which the German military staff used geological help. The series includes contributions to the geology of several areas in Europe of special interest which had been inadequately studied. Elsass, however, was geologically well known, though the province is tectonically complex because the Alpine movements have been superimposed on the older Variscan structure. The authors deal with the province in three divisions. In the North Vosges, pre-Cambrian gneisses and Cambrian rocks have both been folded by the Caledonian movements and succeeded by deposits ranging from middle Devonian to the Trias. In the Middle and South Vosges the gneisses are directly covered by Lower Carboniferous rocks; they have, been altered by granites intruded during the Variscan disturbances which were followed by the deposition of the Permian and the Trias. The third region is the rift-valley of the Rhine with Oligocene, Pliocene, and Pleistocene deposits. The monograph contributes much fresh information, as well as summarising the evidence on these three important geological divisions.
