Three Little Pegmatites

Friday, 12 February 2021 08:00 AM

Three famous phosphate loaded pegmatites - The Palermo, Hagendorf, and Tip Top Pegmatites.

Scholzite

and/or Parascholzite - #BN54995
Locality
Hagendorf-Süd, Oberpfälzer Wald, Bavaria, Germany 
Formula
CaZn2(PO4)2·2H2
Availability

Price

Size
7 x 6 x 7 cm - Sm Cabinet 
Tagged
phosphate , pegmatite mineral  

A very rich specimen loaded with 1-2mm bladed and prismatic crystals of Scholzite (stubby prismatic with nearly square cross-sections) and Parascholzite (long, prismatic, more bladed). These descriptions are very generalized, but are based on photos from two books: "Hagendorf" by J. Kastning and J. Schluter and "Palermo" by Whitmore and Lawrence.  The descriptions on Mindat more or less follow these descriptions. At the Tip Top mine, Parascholzite crystals are also long and bladed. Having said that, the specimen should be analyzed (XRD) to determine which is which.
