Mineralogical compositions of sand tempers in tan-paste sherds from Nukuleka and Nëndo
| Grain type | Nukuleka (To2537) n = 545 | Nukuleka (To3750) n = 555 | Nukuleka (To2070) n = 440 | Nukuleka (99–10) n = 400 | Nëndo (SZ8-68/12) n = 400 |
|---|---|---|---|---|---|
| Quartz | 1 | 1 | 3 ± 1 | 19 ± 2 | 19 ± 2 |
| Plagioclase | 8 ± 1 | 14 ± 1 | 22 ± 2 | 12 ± 2 | 14 ± 2 |
| Clinopyroxene | 76 ± 2 | 74 ± 2 | 62 ± 2 | 58 ± 3 | 52 ± 3 |
| Hornblende | 2 ± 1 | trace | trace | 1 | 2 ± 1 |
| Opaques | 9 ± 1 | 5 ± 1 | 9 ± 1 | 4 ± 1 | 6 ± 1 |
| VRF | 4 ± 1 | 6 ± 1 | 4 ± 1 | 6 ± 1 | 7 ± 1 |
Individual sherd labels are in parentheses. Figures are grain frequency percentages based on counts of n grains in thin section. Opaques are opaque iron oxides, mainly magnetite. VRF denotes polycrystalline and polyminerallic volcanic rock fragments. Standard deviation (±) of counting error given by [p(100 − p)/n]1/2 where p is percentage. See Fig. 2 for locations.
