Mineralogical notes. No. III. Axinite, petterdite, crocoite, and datolite
Abstract
Axinite was first found at this locality by Mr. D. A. Porter, to whom I am indebted for notes as to its mode of occurrence. The exact location is about a quarter of a mile from the footbridge over the Peel River, where the mineral is found associated with green epidote in sedimentary rocks much altered by intrusive diorite; it occurs sometimes in crystalline veins, but the best specimens are obtained in cavities, where the crystals have grown freely, accompanied by small well-formed quartz prisms. Good crystals are rare and minute; larger, more imperfect ones can be found measuring up to 15 mm. The colour is brownish with a violet tinge on a fresh fracture.
