History of Geology in Wales

Posted by John Henry on Jan 12, 2019

Best wishes for the New Year to all website visitors and customers. January's article features maps, memoirs and books concerning the geology of Wales and the rich history there of the development of geology. That Wales gives the names of three of the systems of the stratigraphical chart – Silurian, Ordovician and Cambrian and, until recently Precambrian, attests to the early exploration and conceptual thinking that occurred here.

French Geological Maps

Posted by John Henry on Nov 25, 2018

This is the first in a series of articles about new and interesting catalogue entries. This month I’ve started with French Geological Maps, including the 1841 Carte Géologique de la France, the first geological map of all of France. Its authors, Pierre-Armand Dufrénoy (1792-1857) and Léonce Élie de Beaumont (1798-1874), were directed to produce this map of all France by Brochant de Villiers, professor of geology at the École des Mines, in response to the Geological Society of London’s Geological Map of England and Wales, published 1819-20.
