Bobfergusonite : Na2Mn5FeAl(PO4)6

This image is copyrighted. Unauthorized reproduction prohibited.

Sample size is 10 cm x 6 cm. The sample shows the characteristic schiller of Bobfergusonite. The darker green phase associated with Bobfergusonite may be Manitobaite.

This sample and a suite of others were collected from the loose rock surrounding the #22 Dyke in October 1989. The dyke was still largely intact and phosphate pods containing Bobfergusonite and separate phosphate pods containing the Beusite suite were exposed in outcrop.
