Mantle Rock from Salt Lake
Earth's mantle, an olivine-rich rock, starts about 3-4 miles (5-6km)
below the ocean floor and goes down 1,800 miles (2860km). It's actually 80% of the
Earth's volume. Lava is melted mantle rock. It flows from the Earth, as you see
in Hawai‘i , but heavy mantle rock, our sample, usually doesn't erupt.
Lherzolite found at Salt Lake Crater, O`ahu.
