...Martine Clet; Serge Occhietti Abstract Lotbinière Sand and Deschaillons Varves are indicators of the drainage pattern of the St. Lawrence watershed, which presumably occurred during the Late Sangamonian (5c and 5c–5b transition?). The pollen content of the Lotbinière Sand suggests there was a Picea...

... between 90 and 70 ka. This advance was preceded and followed by periods of free drainage during which were deposited the Lotbiniere Sand and St. Pierre Sediments, two nonglacial units dated at or beyond the limit of the radiocarbon method. Available evidence suggests that the Deschaillons Varves were...

... ) that were deposited over the shallow-water, siliciclastic sands of the lower part of the Chazy Group ( Globensky 1987 ) and recorded a progressive deepening-upward cycle. Regional facies distribution, lithotectonic elements, and significant thickness variations indicate several depocenters and local growth...

... indicating greater continental ice volume and colder climate. Correlation with the Lotbinière Sand of inferred late Sangamonian age ( Lamothe 1989 ) is tempting, although the latter has yet to be identified below about –10 m. Alternatively, these wood fragments may have been simply deposited in a subaqueous...

.... The matrix consists of fine-grained quartz sand and fragments of phosphatized fossils (brachiopod, crinoid ossicles, and bryozoans). These three proxies have been used to define ultramafic provenance for shale, wherein elevated Cr and Ni concentrations and Cr/Ni ratio (∼1.6) suggest an ultramafic...
