Natural Qaamarujuk fjord sediments (pre-mining)
West Greenland, Maarmorilik, Greenland
Sediments
- Type
- Sediment
Lead geochemical background (18 to 25 mg/kg) at stations 12, 16 and 17, dated by 210Pb, 1 to 19 km from the mine. Station 12, the closest, is slightly richer in 207Pb, probably through natural weathering of outcropping ore. Indicative coordinates.
