Usselo is the type site for the 'Usselo Soil', which is also known as either the 'Usselo horizon' or 'Usselo layer'. It is a distinctive and widespread Weichselian (Lateglacial) buried soil, paleosol, that is found within Lateglacial eolian sediments known as 'cover sands' in the Netherlands, western Germany, and western Denmark. This paleosol ...

2009年7月20日 · Recent claims that the Usselo soil represents an event layer from rapid aeolian sedimentation caused by an extraterrestrial impact is rejected. Instead, both Usselo and Finow soils can be assumed to be pedostratigraphical marker …

In 1940, a dark charcoal-rich layer, 10 to 15cm thick, was found within the Late Pleistocene Coversands of the Netherlands, and named the Usselo Layer (de Laag van Usselo) by its discoverer, archaeologist CCJW Hijszeler (1902-1982). Usselo is a village near Enschedé, a few kilometres from the Dutch-German border.

From the people who knew, or knew about the existence of the Usselo horizon in northwestern Europe, only very few, perhaps two or three, heard about its discovery in White Russia, and a few others, perhaps three or four, about the discovery in Egypt, attributed to the Alleroed by radiocarbon dating, backed up by palynological, paleontological ...

2012年4月30日 · We examined the Usselo soil horizon at Geldrop-Aalsterhut (The Netherlands), which formed during the Allerød/Early Younger Dryas and would have captured such impact material. Our accelerator mass spectrometry radiocarbon dates of 14 individual charcoal particles are internally consistent and show that wildfires occurred well after the proposed ...

2021年6月5日 · The Usselo horizon was found at a depth of 18 meters, significantly by an overseer. The experts who describe the unconsolidated sediments not once use the word charcoal. Only one contributor, Havinga, perhaps a rebellious type, speaks of the Usselo horizon as “a layer of white sand with black speckles”.

2019年4月24日 · The Usselo soils are mostly classified as the Albic Arenosols; they typically consist of greyish Ahb and Eb horizons, and frequently bear charcoal indicating widespread and repeated fires of...

2022年11月23日 · At present 3 hypothesis are in mind to explain the Usselo Horizon ’s characteristics. 1) One or many cometary nuclei atmospheric explosions/ fireballs and impact events. 2) One or more mega solar...

They found the charcoal layer in West Germany, but do not mention the name Usselo – while the German geologists do so routinely: Der Usselo Horizont. Van Mourik and Slotboom, in 1995, went much too far – sorcerer’s apprentices who believed they had mastered the vanishing act.

The recent claim that the Usselo soil is an event layer from rapid aeolian sedimentation by an ET impact is rejected. Instead, both the Usselo and Finow soils can be considered as pedostratigraphical marker horizons in northern central Europe …
