Present-day Gardon sediments (main stream, November 2011)
Gard, Gardon catchment, France
Sediments
- Type
- Sediment
Gardon catchment, a former mining district (Pb-Zn, pyrite, Sb, coal) now industrialised; δ66Zn narrow in sediments, poorly discriminating between mining sources, but sediments of acid-drainage tributaries are lighter (about +0.07 ‰) than the local ore (+0.18 ‰, unpublished) (Resongles et al., 2014). Main-stream sediments sampled at high flow in November 2011: δ66Zn of +0.18 to +0.25 ‰, decreasing downstream, within the archive range. Indicative coordinates; those of each station are in the notes.
