The Dating Game – The age of the Earth and modern geochronology.

The North Staffordshire Group of the Geologists’ Association (NSGGA) will be holding their next talk on Thursday evening (14th January). The talk will be delivered by Keele’s Dr Ralf Halama and is entitled: 

The Dating Game – The age of the Earth and modern geochronology.  

Date: Thursday, 14th January at 7:30 pm via Zoom. 

NSGGA members have been sent a link to join the Zoom session. Some additional places are available on request via nsgga.org/contact

Abstract: Our understanding of the chronology of the Earth’s evolution represents the fulfilment of a quest that is one of the most spectacular achievements of modern science. This presentation will illuminate how we can determine the age of the Earth and how modern geochronological methods are applied to solve geological questions of far-reaching significance. 

The evolution of scientific progress in dating the Earth from attempts in the late 19th and early 20th century to our present knowledge is truly fascinating. Equally impressive is the establishment of the Earth’s age of around 4.5 billion years in the 1950s by Clair Patterson, still valid today. Nevertheless, current scientific discussion about the age of the Earth continues to be vibrant, focusing on interpreting the significance of the Earth’s age. Modern geochronology applies a wide range of state-of-the-art analytical techniques that provide always new and exciting insights about the geological evolution of Earth in time. This will lead into a brief foray into the wonders of modern geochronology, from dating micrometre-sized domains in the oldest minerals on Earth to detecting episodes of mineral crystallization during mountain building.
