About Our Field Sites
Our four working groups gather samples from around the world using drill cores, pore fluids, water columns, and in many cases, a trusty rock hammer. Many of these rocks are Precambrian, formed more than 500 million years ago, when Earth hosted minimal animal life.
What can rocks tell us?
After obtaining samples, researchers can extract data in a laboratory. Careful observation combined with geochemical analysis enable us to understand environmental conditions during the development of life on Earth. With a better idea of what Earth looked like as life emerged, we can expand our search for life on other planets.
