«Ancient meteorite impact sparked long - lived volcanic eruptions on Earth.» (sciencedaily.com)
By studying the magnetic orientations in pristine samples of ancient meteorites that formed 4.563 billion years ago, the team determined that the solar nebula lasted around 3 to 4 million years. (sciencedaily.com)
In a fascinating set of projects we will look at the smallest scales and back in time, probing the mineralogy and composition of micron - sized grains in ancient meteorites using the most sophisticated microscopic techniques, to explore the history of volatiles and organics in planetary building blocks at the time when the Solar System was young.
