Discover Earth Sciences Lectures

30 November 2021

Discover Earth Sciences is a live lecture series that highlights the fascinating and diverse world of Earth science.

Geochronology Lab at UCL

The aim of this lecture series is to showcase how maths, chemistry, physics, geography and biology can all link to the many different facets of Earth science. The lectures are being held on Zoom, and we were very lucky to have Prof. Pieter Vermeesch kick off the lecture series on his geochronology talk entitled, ‘How to date rocks with radiogenic isotopes’.

Pieter’s talk took us on a journey through Earth’s timeline and revealed how (1) the uranium-lead (U-Pb) method was used to estimate the age of the Solar System (4.57 billion years), (2) the potassium-argon (K-Ar) method was used to date the extinction of the dinosaurs, and (3) the fission track method was used to estimate the vertical growth rate of the Himalaya.

This is only the start of the Discover Earth Sciences series which will be continuing next term so if you want to find out more about the research here at UCL or know A Level, GCSE students or members of the public that might be interested in discovering Earth science then keep an eye out on the UCL ES twitter for the next announcement!
