HOLMES AND THE INDELICATE QUESTION: MEASURING THE DEPTHS OF TIME WITH THE CLOCKS OF THE EARTH  


This page provides a PDF version of the presentation for the Plenary Lecture delivered at the 2014 GAC-MAC Annual Conference held in Fredericton, NB, in May 2014. The lecture was intended to mark the 100th Anniversary of the publication of Arthur Holmes' landmark book "The Age of the Earth", which is widely seen as the beginning of the modern science of geochronology. It also provides an explanatory document containing additional information on the individual slides in the presentation. This information was placed on the internet in response to several requests for access to material that might be useful for teaching or other purposes. Users are asked to please reference the source of the material, and also to remember that the preparation of the lecture and material involved drawing on the work of others who have written on the topic of the Age of the Earth. In particular, I acknowledge the excellent books by Cherry Lewis (the Dating Game), Derek York (In Search of Lost Time) and Anthony Hallam (Great Geological Controversies).
