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 ...

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.

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 …

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 ...

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 ...

1989年8月30日 · The new Usselo section spans most of the Lateglacial stratigraphical succession of the Netherlands. The base of the sampled section is dated c. 12,880 B.P. Since this sandy base already has thermophilous insects, it is evident that it begins after the initial climatic warming at the beginning of the Lateglacial.

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...

2018年6月1日 · Two types of paleosols with ‘Usselo soil’ characteristics (initial podzol and abundant charcoal) could be distinguished. The first paleosol type (type 1) holds a relatively loamy, dense layer, and exhibits distinct cryoturbation (frost …

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.
