Sedimentology

[Sedimentological analysis of all U-channels with CT-Scan and X-radiography in high resolution (Fortin). Geochemistry analysis using micro-XRF at 100 μm for 3 selected intervals (Jouve); Analysis of sedimentary facies from thin-sections (Jouve). Interlaboratory comparison with low-resolution μ-XRF performed at Univ. Bremen (Francus). Project coordination within Canada (Fortin). International project coordination (Francus)].

Fortin and Francus participated to the fieldwork and to the recovery of the long sedimentary sequence in
Patagonia. Four long sections from sites 1 and two long sections from site 2, both from the deep central
basin, were collected. Jouve was hired in January 2009. Jouve, Fortin and Francus took
part to the core opening and sampling party held in Bremen (Germany) in May and June 2009. Site 2 was
selected for establishing a continuous composite sequence from which all the samples for the long climate
reconstruction will be taken because it was finer grained and less disturbed than site 1. The preliminary
results of the drilling were presented at the joint AGU meeting in Toronto (May 2009) and in a paper
within the forthcoming issue of “Scientific Drilling” . During the sampling party, Francus and
Jouve, in agreement and collaboration with our international partners, selected three intervals for highresolution
analysis aiming to collect the warmest intervals with little or no disturbance, and intervals that
were the best potential recorders of rapid environmental changes. Selection was based on sedimentary
facies, on-site measurements (including magnetic susceptibility), core-logging measurements and
stratigraphic correlation based on the recognition of a prominent tephra in the core.

Queen’s University: Scott Lamoureux (co-PI)

[Grain-size analysis of 3 intervals selected for high resolution analysis, interlaboratory comparison with Univ. Bremen. Lamoureux will act as the cosupervisor of PhD student G. Jouve (INRS-ETE) to help him with paelohydrological interpretation of grain-size analysis].

Scott Lamoureux was not directly involved in the drilling activities, but has participated in the discussions
to develop our research plans and collect samples when the sediment cores arrive in Bremen. He will host
Guillaume Jouve for a few months for the grain-size analysis to be performed at Queen’s University.
