Imagine reading a complex 450-page book that is missing the first 14 pages. And for the next 50 pages you only have words and incomplete sentences. Piecing together an accurate storyline would be difficult with such little information. Geologists face this challenge when piecing together Earth’s early history. There is one tool, remnant from that ancient time which still does exist, at least as far back as 4.4 billion of the Earth’s 4.54 billion year history zircon mineral grains.
This talk will give a background of oxygen isotopes in zircons from younger rocks that allowed the interpretation of the world s oldest mineral and the implications of liquid water on our planet 160 million years after the formation of our planet.
Presented by Liz King, Geologists of Jackson Hole.
