Part of the Lapworth Lecture Series
Speaker: Dr Daniel Condon. NERC Isotope Geosciences Laboratory
In 1913, Frederick Soddy’s research on the fundamentals of radioactivity led to the discovery of “isotopes.” Later that same year, Arthur Holmes published his now famous book The Age of the Earth, in which he applied this new science of radioactivity to the quantification of geologic time. Combined, these two landmark events did much to establish the field of “isotope geochronology” – the science that underpins our knowledge of the absolute age of most Earth (and extra-terrestrial) materials. This talk brings together modern perspectives on the continually evolving field of isotope geochronology, highlighting the continuing development analytical methods, and a range of applications, from the early evolution of the Solar System to our understanding of Quaternary climate change, and from the 4.5 billion years in between.
