| Species: | Fluorapatite | |
| Formula: | Ca5(PO4)3F | |
| Comments: | "The Tollgate Mine has some very large manganapatite. It was observed in massive sections up to four inches across. The greatest amount is smaller in size but also massive. No individual crystals were observed here. The material is associated with the mica, feldspar, quartz and secondary uranium minerals." (Jones 1960) "in short six and twelve-sided prisms, from one quarter, to above an inch in diameter. Their color varies from pale reddish white, through bluish white to asparagus-green; and where penetrated by [uranophane] they present a citron-yellow color." (Shepard 1837) Accessory in the quartz-microcline zone. "Apatite occurs in aggregates of subhedral pale green crystals that average 1/4 inch in diameter. The aggregates are 3 inches to 2 feet in diameter and occur chiefly in perthite masses. Almost all of them contain subhedral plates of columbite-tantalite 1/8 to 1 inch long." (Cameron 1954) | |
