Outwash deposits

The site is situated on a glacial outwash plain, and surface deposits consist of fill and undisturbed gravel and sand outwash containing minor silt and peat. Underlying the outwash at a depth of 20 or more feet is glacial till. Groundwater occurs under water table conditions within the highly permeable outwash deposits at a depth of 8 to 12 ft across the site. 

Bq/m in soils formed from coarse glacial outwash deposits with 2.3 ppm uranium, and the other from Reading Prong, New Jersey, with soil-gas radon levels from 1,081 to 27,027 pCi radon-222/L of air (40,000 to 1,000,000 Bq/m (Michel 1987). Hopke (1987) states that normal soil-gas radon measurements are in the range of 270 to 675 pCi radon-222/L of air (10,000 to... 

The deposits of till and glacial outwash deposits in the Transantarctic Mountains are especially noteworthy because their very existence at sites well above the level of the present outlet glaciers indicates either the thickness of the glaciers that once flowed across the Transantarctic Mountains or the amount of uplift of the mountains relative to a more or less constant thickness of the East Antarctic ice sheet. Therefore, we approach this topic with questions about the age (or ages) of the...

Lodgment till and associated periglacial outwash deposits occur widely in the Transantarctic Mountains. Although all of the Cenozoic glacial deposits are now included in the Sirius Group, these deposits are difficult to date because the microfossils they contain are reworked and because the various kinds of plant ronains they may contain are not sufficiently time-sensitive to determine their depositional ages.
