Rhine at Rheinzabern (placer, detrital Ru-Os-Ir alloys)

Rhineland-Palatinate, Upper Rhine, Germany

Sediments

Type: Sediment

Detrital Ru-Os-Ir alloys from Upper Rhine gold and platinum-group mineral placers; Dijkstra et al. (2016) link them to Paleozoic residual peridotites of the Alps, accreted with the Armorican terranes before the Variscan orogeny. Over the four localities, main mode at 0.1244 (Re-depletion age 0.48 Ga) and inflection point at 0.1205 (1.06 Ga). Locality D of the appendix. Coordinates not published.
