Identification Type Mineral
Name Rutile
Distinguishing Features
Description Transparent gray-green. Nonpleochroic. Strong second-order birefringence with vivid colors. High relief.

Usually detrital, but in rare cases may form diagenetically (M. Talbot, pers. comm). May appear as multiple contact twins.

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.
