Stratified deposit. Mn ores form lenses and seams in carbonate sediments and pyroclastic rocks.

Note: Seghir et al (2012) seem to refer to another locality with the same name in southwestern Algeria (Béchar Province?).

Detailed Mineral List:

ⓘ Adelite ?
Formula: CaMg(AsO4)(OH)
ⓘ Albite
Formula: Na(AlSi3O8)
ⓘ Albite var. Oligoclase
Formula: (Na,Ca)[Al(Si,Al)Si2O8]
ⓘ Baryte
Formula: BaSO4
ⓘ 'Biotite'
Formula: K(Fe2+/Mg)2(Al/Fe3+/Mg/Ti)([Si/Al/Fe]2Si2O10)(OH/F)2
ⓘ Braunite
Formula: Mn2+Mn3+6(SiO4)O8
ⓘ Bustamite
Formula: CaMn2+(Si2O6)
ⓘ Calcite
Formula: CaCO3
ⓘ 'Chlorite Group'
ⓘ Fluorite
Formula: CaF2
ⓘ Hausmannite
Formula: Mn2+Mn3+2O4
ⓘ Katophorite
Formula: {Na}{CaNa}{Mg4Al}[(AlSi7)O22](OH)2
Description: Byramjee R.and Meindre M.(1956)publish the following normalized amphibole composition: (Na0.394K0.243)0.637(Na1.242Ca0.758)2.00(Mg4.139Mn0.311Fe0.068Al0.471Ti0.010)5.00(Si7.894Al0.106)O22((OH)2. Their data does not give a Fe3+/(Fe3+ + Fe2+) ratio, but charge balance calculations give sufficient Fe3+ for the amphibole to fall within the katophorite range as defined by Hawthorne et al. (2012)
ⓘ Laumontite
Formula: CaAl2Si4O12 · 4H2O
ⓘ Microcline
Formula: K(AlSi3O8)
ⓘ Piemontite
Formula: (CaCa)(AlAlMn3+)O[Si2O7][SiO4](OH)
ⓘ 'Psilomelane'
ⓘ Pyrolusite
Formula: Mn4+O2
ⓘ Quartz
Formula: SiO2
ⓘ Quartz var. Chalcedony
Formula: SiO2
ⓘ Rhodonite
Formula: CaMn3Mn[Si5O15]
ⓘ Spessartine
Formula: Mn2+3Al2(SiO4)3
ⓘ Tilasite
Formula: CaMg(AsO4)F
ⓘ Winchite ?
Formula: ◻{CaNa}{Mg4Al}(Si8O22)(OH)2
Description: An analysis published by Byramjee R.and Meindre M.(1956) gives a composition near the richterite-winchite-katophorite join. The composition falls within a katophorite composition following the species definitions outlined in the amphibole nomenclature by Hawthorne et al.(2012). See the katophorite entry for more details.
