For over a century, mineral prospectors have known that a rock known as kimberlite often contains diamonds. You chances of extracting diamonds in matrix from rock is almost nil. The top 5 diamond mining nations are Russia, Botswana, Democratic Republic of Congo (DRC), Australia and Canada. S40RTS does not match the kimberlite records in Antarctica at 120 Ma and Australia at 240 Ma, whereas Case 2 does (Fig 7). Extremely rare in the state, igneous rocks form from hot molten magma that pushes up toward the surface from Earth's interior then cools. These magmas crystallize on cooling into volcanic rocks known as kimberlite and lamproite (see box A).
