Detailed Mineral List:

ⓘ Actinolite
Formula: ◻Ca2(Mg4.5-2.5Fe0.5-2.5)Si8O22(OH)2
ⓘ Annabergite
Formula: Ni3(AsO4)2 · 8H2O
ⓘ Anthophyllite
Formula: ◻{Mg2}{Mg5}(Si8O22)(OH)2
ⓘ Clinohumite
Formula: Mg9(SiO4)4F2
Description: The hydroxylclinohumite is restricted to rocks that show relatively little retrograde alteration. It occurs in rocks mainly consisting of stubby pyroxene crystals cut by veinlets of green serpentine, and lesser amounts of anthophyllite, actinolite, chlorite, phlogopite, magnetite and antigorite. Titanian hydroxylclinohumite occurs as scattered, irregular to rounded grains and grain clusters up to 5 cm across.
ⓘ Enstatite
Formula: Mg2Si2O6
ⓘ 'Fayalite-Forsterite Series'
ⓘ Gedrite
Formula: ◻{Mg2}{Mg3Al2}(Al2Si6O22)(OH)2
ⓘ 'Hornblende Root Name Group'
Formula: ◻Ca2(Z2+4Z3+)(AlSi7O22)(OH,F,Cl)2
ⓘ 'Serpentine Subgroup'
Formula: D3[Si2O5](OH)4
ⓘ 'Serpentine Subgroup var. Nickel-bearing Serpentine'
Formula: D3[Si2O5](OH)4 D = Mg, Fe, Ni, Mn, Al, Zn
ⓘ Spinel
Formula: MgAl2O4
ⓘ Titanite
Formula: CaTi(SiO4)O
ⓘ Willemseite
Formula: Ni3Si4O10(OH)2
