Coverage:

Latitude: 45.911000 * Longitude: -45.234000

Minimum DEPTH, sediment/rock: 0.100 m * Maximum DEPTH, sediment/rock: 6.200 m

Event(s):

HU90-020-074 * Latitude: 45.911000 * Longitude: -45.234000 * Elevation: -972.0 m * Method/Device: Piston corer (PC)

Comment:

Sediments from channel samples were weighed and sieved through a 2 mm mesh. Granules >2 mm were visually identified with a binocular microscope and dolomite was separated from limestone by adding a drop of 10% HCl. The number of grains > 2 mm varied between 28 and 222.
