Back-scattered electron images of olivine and chromium spinel crystals

By California Volcano Observatory 2024 (approx.)
Four grayscale images of slices of angular crystals with bright rims and darker interiors, surrounded by flecks of light gray crystal fragments like confetti. Some of the crystals have bright white patches where inclusions exist, and some have dark cracks running through them. Colored text and dots show where chemical analyses were conducted with an electron beam
