Scope and Contents

Notes for 5 lectures on 'The Origin of the Scenery of the British Isles' given to the Royal Institution in 1884, along with printed abstracts. Sir Archibald Geikie focused on geological formations around the British Isles, with comparisons from European and North American locations, looking at the materials of which they are composed and the processes which went into their creation.

Scope and Contents

Notes for 4 lectures on the 'Volcanic History of Britain', given to the Royal Institution in 1886. Sir Archibald Geikie looked at the emergence of types of geological formations against a geological timeframe and how they have been affected by various processes, especially the action of volcanoes and materials produced by them, within the natural world. He used examples from numerous locations from different parts of the British Isles.

Scope and Contents

Notes and text for seven lectures looking at the geological history of the American continent, looking at specific locations therein, based partly on results from American survey work. These locations were related to to other places around the world, particularly in Britain and Europe. A variety of geological formations were looked at, including that of the continent itself, considering the materials which make them up and the geological timeframe.

Scope and Contents Letter to Sir Archibald Geikie from Capt Clarence Edward Dutton telling him that he is undertaking field work in New Mexico. He is concentrating on the plateau country aided by good topographic maps of the region. He tells Geikie that there are landforms and cliffs similar to those in Utah and Arizona with exposures of Triassic, Permain and Cretaceous strata. These are overlain with evidence of volcanic activity, ancient basalt of 50-200 feet depth on the plateau. Young basalt, in vast lava...

Scope and Contents Letter to Sir Archibald Geikie from Capt Clarence Edward Dutton, thanking him for his articles on weathering and postulating that the Grand Canyon was formed in this manner, and that he is preparing a section concerning this for Geikie's manual. He recommends William Henry Holmes' topographical drawings of the Grand Canyon and reports that photolithographs are being prepared. He gives details of the depths of the individual geological stratifications which can be observed at the Grand...
