Basement Rocks from the Cocos Ridge
Today is the second of the basement sampling party. No this is not like a sale in the basement of Filene’s. This is expensive ignenous rock that we hope will tell us many things.
Last night, I asked at dinner what the story of the day was and Akito’s eyes lit up. Basement rock! Same conversation this morning with Udo. These rocks will confirm (or refute, oh no!) his age model. Basement rock is igneous rock. This is a term geophysicists use to describe the lowest strong, coherent reflector on seismic reflection profiles.
