Kimberlite formations are caused by explosive volcanic eruptions that bring diamonds to the surface from deep within the Earth’s mantle, forming craters known as kimberlite pipes. These eruptions start over 150 kilometers below the surface in the asthenosphere, with magma rising rapidly through the lithosphere, powered by expanding gases like water and carbon dioxide.
