Impact Breccias These rocks are evidence of the Moon’s long history of bombardment from space. Parts of the Moon’s original crust were shattered and strewn across the surface by meteoritic impacts. Later impacts compressed and heated this debris, welding it into the type of rock shown here. Such impact breccias are rare on Earth but abundant on the Moon.
