The coordination number n is equal to 6 for both Co 3 (PO 4) 2 (farringtonite type) and γ-Mn 3 (PO 4) 2, and 5 for δ - Mn 3 (PO 4) 2. The neighboring zig-zag chains are connected together forming layers from penta-membered rings in the case of farringtonite-like compounds and δ - Mn 3 (PO 4) 2.
Structure and composition. It consists of centimeter-sized olivine crystals of peridot quality in an iron-nickel matrix.Coarser metal areas develop Widmanstätten patterns upon etching. Minor constituents are schreibersite, troilite, chromite, pyroxenes, and phosphates (whitlockite, stanfieldite, farringtonite, and merrillite).. Classification and subgroups
For thousands of years people have been fascinated by the ‘heavens above’ and especially so with the mysterious objects that fell to earth.
