EET
96010 original classification in AMN
21, no. 1 as an CV3 chondrite, but several studies have brought information
to light that is inconsistent with that classification. Oxygen isotope data
[1], as well as magnetic susceptibility data [2] and bulk compositional data [3,4,5]
indicate this meteorite is not an CV3 chondrite, but a CM2 chondrite, and one
with extensive hydration like Belgica 7904.
