Volcanism
- Summary:
- Volcanic rocks from Mt. St. Helens, Arenal, El Chichon, Hawaii and Iceland as well as submarine basaltic glass from Galapagos were analyzed using Uranium-thorium dating to determine the age of volcanic deposits. Mauna Kea rocks of alkaline composition > 4000 years old and an old submarine basalt show disequilibrium for several of the nuclides in the (sup 238)U decay chain.
