Nekarot (Wadi Nekarot)
Central Negev, Ramon fault, Israël
OtherFe
- Type
- Fault-controlled hydrothermal iron lenses and stockworks
Ferruginous lenses and iron oxide vein stockworks along major faults, in the Late Cretaceous, in Judea Group carbonates; hematite, goethite, hematitic jasperoids, with calcite, dolomite, minor gypsum and barite. Ore averaging 63 % Fe2O3, mostly goethite. Ore of smelting experiment EXP-6. Brauns et al. (2020): the three Negev ores share the same 187Os/188Os (1.03 to 1.07) but very different Os contents.

| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| 1.0298 ± 0.007 | 1.0221 / 1.0357 | 4 | iron ore (hematite and goethite) Mean and standard deviation recalculated from 4 analyses, 1.0221 to 1.0357 (F.EXP-6-1 1.0357; F.EXP-6-1 réplique 1.0357; F.EXP-6-2 1.0255; IP-39 1.0221). Os: F.EXP-6-1 18932 ppt; F.EXP-6-1 réplique 14407 ppt; F.EXP-6-2 14983 ppt; IP-39 18791 ppt. | Brauns et al. (2020), Osmium isotope analysis as an innovative tool for provenancing anci… |
| 1.0468 ± 0.0243 | 1.0296 / 1.064 | 2 | ore roasted in a wood fire before smelting Mean and standard deviation recalculated from 2 analyses, 1.0296 to 1.0640 (F.EXP-6-50 1.0296; F.EXP-6-50 réplique 1.0640). Os: F.EXP-6-50 15067 ppt; F.EXP-6-50 réplique 13683 ppt. | Brauns et al. (2020), Osmium isotope analysis as an innovative tool for provenancing anci… |
| 1.0496 ± 0.0005 | 1.049 / 1.05 | 3 | bloomery iron (bloom and forged bar) from this ore, experimental smelt Mean and standard deviation recalculated from 3 analyses, 1.0490 to 1.0500 (F.EXP-6-40 1.0500; F.EXP-6-43 1.0490; F.EXP-6-43 réplique 1.0498). Os: F.EXP-6-40 63680 ppt; F.EXP-6-43 63995 ppt; F.EXP-6-43 réplique 63680 ppt. Os enriched in the metal (4 to 28 times the ore) with no change in 187Os/188Os: the ratio carries over from ore to iron, which allows ancient iron to be tied to its ore. | Brauns et al.

| 1.0455 ± 0.009 | 1.0371 / 1.0585 | 5 | slags from the experimental smelt of this ore (tap, furnace and smithing) Mean and standard deviation recalculated from 5 analyses, 1.0371 to 1.0585 (F.EXP-6-5 1.0371; F.EXP-6-19 1.0375; F.EXP-6-21 1.0585; F.EXP-6-21 réplique 1.0501; F.EXP-6-45 1.0445). Os: F.EXP-6-5 188 ppt; F.EXP-6-19 42621 ppt; F.EXP-6-21 50233 ppt; F.EXP-6-21 réplique 12530 ppt. Slag Os contents highly variable: first-tap slag depleted, last-tap and furnace slags enriched. | Brauns et al. (2020), Osmium isotope analysis as an innovative tool for provenancing anci… |
