Backscattered electron
(BSE) image showing forsteritic olivine grains (dark-grey, at center)
with ferrous olivine overgrowths (light grey edges) in the Sahara-97210
(LL3.3) chondrite.
Cathodoluminescence (CL) image showing same region as upper BSE
image. The most forsteritic olivine is rich in Ca and Al and luminesceses
brightly.
