The aftermath of a meteorite striking the surface of a planetary body leaves behind a circular depression in the ground and plumes of dust and rock. The energy left over in the crater can heat up the water that passes through the rocks, creating an environment that could have been responsible for the emergence of microbial life on Earth over 3 billion years ago. In this episode, hosts Gavin Tolometti and Rhys Paterson talk with Earth and Planetary Science M.Sc student Tabetha Shepphard about how she studies the composition of fluids trapped within minerals from the West Clearwater impact structure in Quebec, Canada to learn about hydrothermal systems that developed after the impact event almost 290 million years ago. Also learn how Tabetha start her path towards geology through outreach, politics and speaking primarily French.
