Kulyumbe-section * Latitude Start: 68.000000 * Longitude Start: 88.700000 * Latitude End: 68.000000 * Longitude End: 89.000000 * Location: Kulyumbe river, Siberia, Russia * Method/Device: Geological profile sampling (GEOPRO) * Comment: The profile derives from several outcrops along the Kulyumbe River, located ~100 km E of the Enisej River, at the northwestern margin of the Siberian Platform, where the Middle Cambrian – Lower Ordovician sediments are exposed along ca. 10 km of the Kulyumbe River. The beds are inclined, so their total thickness does not correspond to the topographic elevation between their base and top.
Comment:
Samples were leached for analysis using chemical as given in the parameter comment. The leachate from technique 4 was systematically the least radiogenic and presumably most pristine of all the leachates, and so was used for all the reported analyses.
