...Robert J. Mott; Ian R. Walker; Samantha L. Palmer; Martin Lavoie Abstract Pollen and chironomid analyses and radiocarbon dating at Pye Lake on the eastern shore of Nova Scotia are used to outline the vegetation and climatic history of the area. The coast was deglaciated prior to ∼12 200 14 C BP (14...

... ). The Seymour Lake property, as summarized from Pye (1968) and Blackburn et al. (1991) , is situated within the Caribou Lake-Marshall Lake greenstone belt, a 900-km-long, 150-km-wide, granite-greenstone unit within the Wabigoon subprovince of the Superior province (Figs. 2 and 3 ). The rocks are Precambrian...

Salt weathering could have occurred north of the study area, where a penecontemporaneous salina-type lake existed ( Fig. 3 ). It was a relatively shallow and closed salt lake...

... in the region was carried out at Pye Lake, ∼50 km south of Piper Lake and indicates that climate following the YD became warmer and remained so through the middle Holocene (about 7.0–5.0 cal ka BP). Modern climate became established in the region by about 4.0 cal ka BP ( Jetté and Mott 1995 ). Of note...

...Timothy G. Fisher; Jennifer Horton; Kenneth Lepper; Henry Loope The last aeolian activity of a significant number of inland sand dunes in the southern Great Lakes region (SGLR) was several thousands of years after deglaciation. At Mongo, Indiana, a field of parabolic sand dunes with a variety...

...K. Pye; D. N. Mottershead Abstract Blocks of Forest of Dean Stone, an arkosic, clay-rich sandstone of Lower Carboniferous age, which were used in the construction of a sea wall at Weston-super-Mare in the 1880s, now display extensive honeycomb weathering features. Spatial variations in the degree...

The Elliot Lake Group contains intercalated clastic metasediments and volcanic rocks overlain by deep-water turbidites interpreted to represent a transition...

... are absent. A third possibility is that the clastic sediment was introduced into the lake system via eolian processes. In the study section, grain-size averages are in the very fine- to fine-silt range, typical for distal eolian dust ( Pye 1987 ; Smalley et al. 2005 ), and dust deposition in lakes...
