I need to correct my previous post, "The Usselo Soil and the Younger Dryas Extraterrestrial Impact Hypothesis". Its third paragraph should read:
"One important point that this paper makes is that what has been called either the “Usselo Horizon” or “Usselo Layer” is not a "layer" in terms of being a tabular depositional body of either rock or unconsolidated sediment created separately from the sediments above and below it. Rather, it is a relict, buried Albic Arenosol and Brunic Arenosol (paleosol) that developed in preexisting sediment as the result of a period of surface weathering during a period of nondeposition. As a paleosol, it is pedolostratigraphic marker horizon, not a depositional horizon as some proponents of the Younger Dryas extraterrestrial impact hypothesis imply by the use of the term “horizon”." the first paragraph should read: "A new paper, which in press in “Boreas” about the Usselo Soil and the Younger Dryas extraterrestrial impact hypothesis, has recently appeared. It is:" I apologize for not being a better editor.
