Site name: Mubwindi Swamp, Uganda
Light type: Plane-Polarized Light
Magnification: 630.0
Submitted by: Mark Shapley
Notes: Unusually large titanium-bearing mineral grain from basal material underlying a tropical peatland. Peculiar grain shape appears to reflect paragenesis as a complex diagenetic aggregate.
