Survey Description
In 1968, 1978-79, stream sediment sampling surveys were conducted in the Chaleur Bay area, south-east of the Gaspé Peninsula. These surveys cover 4600 km 2. Approximately 13,000 samples were collected at 500 m spacing, along streams at an average density of 1 sample per 0.4 km 2 . In 1968, the sampling was done by Soquem and the samples were transferred to MERQ. In 1978-79, the sampling was done by MERQ. The samples were analysed for:
| Element | Dissolution | Technique |
| Cu, Zn, Pb, Ni, Co, Mn, Ag |
HNO 3 |
atomic absorption (AAS) |
| Mo | HCl | atomic absorption (AAS) |
| Sn |
NH 4I, HCl |
atomic absorption (AAS) |
| U |
HNO 3 |
paper chromatography |
The data are published in Ministère de l’Énergie et des ressources open files DPV-854 (geochemical atlas) and DPV-855 (raw data).
In 1985, a total of 1960 samples were reanalysed for arsenic and data are published in Open File MB 85-21.
