Geological map, colour lithograph, Geological Map of the
British Isles, by Archibald Geikie, published by W and A K
Johnston, Edinburgh and London, 1879.
Notice that the stratigraphical column has, lower right, the Cambrian and Silurian directly adjacent. 1879 was the year that Charles Lapworth resolved the controversy between Adam Sedgwick and Roderick Murchison over these two eras, by inserting a new era, Ordovician, in between. But it isn't shown on this map. |
