RM1172   Fluorapatite with hematite and calcite
Ca₅(PO₄)₃F
  -  8. Phosphates, arsenates and vanadates

Excellent specimen of fluorapatite from "Jumilla".A group of crystals, one of them predominant, vertical, isolated, brilliant, transparent, with good color and no damage. It is disposed in a cavity accompanied by globular aggregates of calcite and laminar hematite crystals. This specimen is from dumps and already have a certain age. Interesting matrix: A very esthetic and representative piece from this classic Spanish locality were nowadays is forbiden collect minerals.
This locality is located in La Celia volcano where we find remains of a volcanic neck (chimney) and streams from Pliocenic age (1.8 - 5 million years). These mines have a special geological interest, as they contains an exceptional locality for fluorapatite in the volcanic rock "jumillite". Jumillite is a volcanic rock of the lamproite group, a variety of phonolitic leucitite, consisting essentially of diopside and leucite and, to a lesser content, by olivine, alkali feldspar and phlogopite.

Size: 9.3 x 8.2 x 6.3 cm.
Main crystal: 12 x 5 mm.
Found in ca 1990's.
Calcite is fluorescent under LW-UV.
