The occurrence of magnesian skarn from Valea Rea occurs in the close proximity of the southern contact of the intrusive body with Anisian dolostones pertaining to the Ferice Unit. The skarn, investigated with an exploration mine shaft, is forsterite- and phlogopite-bearing, located near the contact. The skarn consists of a mass of forsterite (Fo = 97.28–98.54 mol.%, Fa = 1.46–2.62 mol.%, Tep = 0–0.20 mol.% — symbols for olivine end-members), occurring as relics in mesh textures of chrysotile and lizardite.

The fluorapatite is characterised by an excess F content.
