| ⓘ Calcite Formula: CaCO3 |
| ⓘ Dolomite Formula: CaMg(CO3)2 References: von Knorring, O., Clifford, T. N. (1960) On a skarn monazite occurrence from the Namib desert near Usakos, South-West Africa. Mineralogical Magazine and Journal of the Mineralogical Society, 32 (251) 650-653 doi:10.1180/minmag.1960.032.251.06 |
| ⓘ 'Garnet Group' Formula: X3Z2(SiO4)3 |
| ⓘ Goethite Formula: Fe3+O(OH) |
| ⓘ Graphite Formula: C |
| ⓘ Magnetite Formula: Fe2+Fe3+2O4 |
| ✪ Monazite-(Ce) Formula: Ce(PO4) Description: Crystals to 15cm are found in Dolomite and Calcite, reddish brown and translucent. Due to their low radioactivity they are not metamict.

Geochronology
Mineralization age: Cambrian : 500 ± 20 MaImportant note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
