- Summary:
- Mauna Kea is the highest of five volcanoes that makes up the island of Hawaii. It is also the only mountain in the central Pacific Ocean that is known to have been glaciated. As indicated by interstratification of glacial drift and volcanic rocks on the upper slopes of the mountain, a summit ice cap of about 70 km(super 2) formed at least four times during the middle and late Pleistocene. The rocks and sediments that are found on this volcano are divided into an older Hamakua Group that is dominated by a tholeiitic suite that includes basalt, olivine basalt, and oceanite and a younger Laupahoehoe Group of alkalic rocks that are dominated by hawaiite.
