“…An additional specimen was collected from Triassic Fremouw Formation strata at the base of Mount Falla, also in the Beardmore Glacier area (Barrett et al 1986). Peat blocks were cut into sections, and the flat surfaces were polished and then etched in 48%-50% hydrofluoric acid.…”

Highly productive polar forests from the Permian of Antarctica

“…The LP1 and LP2 apparently were more productive than the other contemporaneous forests that developed under similar paleoclimate, paleoenvironmental and soil nutrient conditions, which were enhanced by the occurrence of volcanic rock fragments in the sand (Barrett et al, 1986;Isbell, 1990).…”

“…The Permian sequence consists of: 1) glacigenic, primarily glacial marine and glacial lacustrine deposits recording Gondwanan glaciation (Pagoda Formation, Isbell et al, 1997;; 2) shale and interbedded sandstone deposited in a large post-glacial lake or series of lakes filled by deltaic sediments (Mackellar Formation and lowermost Fairchild Formation, Miller, M.F., et al, 2010); 3) crossbedded sandstone lacking plant fossils deposited in braided stream channels (bulk of Fairchild Formation, Barrett et al, 1986); and sandstone, siltstone, shale and coal deposited in braided stream systems (Buckley Formation, Isbell, 1990;Isbell et al, 1997;Gulbranson et al, 2012Gulbranson et al, , 2014. The amount of plant material and the thickness and extent of coal increases upward within the Buckley Formation.…”
