Excerpt from On Some Bone-and Cave-Deposits of the Reindeer-Period in the South of France
The Valley of the Vezere River and Cafe - The river Vezere, which takes its rise near Chavagne, in the Department of the Correze, enters Dordogne as a considerable stream near Terrasson, and, after pursuing a tortuous course in a south-westerly direction for about thirty miles as the crow ¿ies, joins the river Dordogne at Limeuil a few miles south of Le Bugue. In the neighbourhood of Terrasson the Vezere passes over a small tract Of Carboniferous beds, which are regularly worked for coal; but by the time it reaches Condat, where first we joined the river, its valley is excavated through rocks belonging to the Jurassic series, which near Aubas, a few miles lower down, are exchanged for those Of the Cretaceous system. It is neither in my power, nor is it in the slightest degree necessary for my subject, to enter into any stratigraphical details With regard to this succession Of beds, which, however, in general appearance, present a considerable contrast to their equivalents in this country. I will only men tion that the Cretaceous beds, from the Lower Greensand upwards I, assume, in the Department Of the Dordogne, the form of a compact limestone, more or less arenaceous in its different subdivisions, which also vary considerably in hardness.
