Most ordinary chondrites have exposure ages of less than 50 million years, and most carbonaceous chondrites less than 20 million years. Achondrites have ages that cluster between 20 and 30 million years.
How can you tell how old a meteorite is?
The ages of Earth and Moon rocks and of meteorites are measured by the decay of long-lived radioactive isotopes of elements that occur naturally in rocks and minerals and that decay with half lives of 700 million to more than 100 billion years to stable isotopes of other elements.
Where did carbonaceous chondrites originate?
Most carbonaceous chondrites are thought to come from the low-albedo, C-type asteroids, which are the most abundant type between 2.7 and 3.4 AU (Bell et al., 1989), CM chondrites may be derived from an altered C-like asteroid called G-type (Burbine et al., 2002).
