ⓘ 'Andradite-Grossular Series'

ⓘ Calcite
Formula: CaCO3
ⓘ Clinochlore

ⓘ Diopside
Formula: CaMgSi2O6
ⓘ Epidote

ⓘ 'Feldspar Group'
ⓘ Hematite
Formula: Fe2O3
ⓘ Muscovite
Formula: KAl2(AlSi3O10)(OH)2
ⓘ Muscovite var. Sericite
Formula: KAl2(AlSi3O10)(OH)2
ⓘ Piemontite
Formula: (CaCa)(AlAlMn3+)O[Si2O7][SiO4](OH)
Description: First only visually identified and tentatively identified as piemontite(Størseth 2019 a). Later shown by PXRD/SEM to be epidote/Mn-rich epidote in composition(Størseth 2019b)
ⓘ 'Plagioclase'
Formula: (Na,Ca)[(Si,Al)AlSi2]O8
ⓘ Prehnite
Formula: Ca2Al2Si3O10(OH)2
ⓘ 'Pyrochlore Group' ?
Formula: A2Nb2(O,OH)6Z
ⓘ 'Pyrochlore Group var. Uranpyrochlore (of Hogarth 1977)' ?
Formula: (Ca,U,Ce)2(Nb,Ti,Ta)2O6(OH,F)
Habit: Primary dark brownish grains with a greasy lustre alongside a secondary unknown yellow phase (under work)
Description: Reported in Størseth (2019). The chemical composition of a dark brownish grains with a greasy lustre was found to be: Nb2O5: 29.5%, Ta2O5: 2.3% , SiO2:2.6%, TiO2: 18,1%; UO2: 36.9%, Al2O3: 0.3% , Fe2O3 2.3%, Cao 7.3%, F 0.7%. Analysis by Alf Olav Larsen It was found that it might have similarities with "uranpyrochlore". The analyzed specimen had a yellowish-orange secondary phase. Newer analytical work by T. Husdal possibly points towards carlosbarbosaite for this phase, but analytical work is still under way (status: June 2026).
ⓘ 'Pyroxene Group'
Formula: ADSi2O6
ⓘ Quartz
Formula: SiO2
ⓘ Rhodochrosite
Formula: MnCO3
ⓘ Titanite
Formula: CaTiO(SiO4)
ⓘ Vesuvianite
Formula: Ca19Fe3+Al4(Al6Mg2)(◻4)◻[Si2O7]4[(SiO4)10]O(OH)9
ⓘ Zoisite
Formula: (CaCa)(AlAlAl)O[Si2O7][SiO4](OH)
Description: In the book "Norges Mineraler" by Lars O. Kvamsdal the following is written about the zoisite from Mjønes: The Mn-content is to low for the mineral to be called thulite (Støreseth 2019) and Støreseth (2019b)
ⓘ Zoisite var. Thulite
Formula: (Ca2)(Al,Mn3+)3(Si2O7)(SiO4)O(OH)
Description: By definition, thulite is a pink variety of zoisite with a variable manganese content. The pink zoisite -bearing rock found at Mjønes Tunnel is populary as a whole called thulite. The "Thulite"- rock contains beside a pink variety of zoisite, varying amounts of minerals such as quartz, piemontite, feldspar, and tremolite. PXRD analysis confirms that the pink mineral labelled by collectors as "thulite" is zoisite. SEM/EDS analyses of the pink zoisite indicate 0.1 wt% Mn₂O₃, a relatively low manganese content (Størseth 2019)[[1]] and Størseth (2019) [[2]]. In the book "Minerals of Norway" by Lars Olav Kvamsdal (2023) [[3]] the following is written about the zoisite from Mjønes: "The Mn-content is to low for the mineral to be called thulite (Størseth 2019) and Størseth (2019b)". However, since, by definition thulite is a pink variety of zoisite and it's generally based definition is not based on the content of Mn, but the color, thulite (as the poink variety of zoisite) does occur at Mjønes.
