The extraterrestrial matter falls in west-central Poland (Great Poland Lowland); historical and geological data

Stankowski W. T. J.

Acta Geologica Polonica

2015

Vol. 65, no. 2

263--268

Direct and indirect evidence of falls of extraterrestrial matter in west-central Poland (Great Poland Lowland) is proved historically and environmentally. The chronological list of such events has historical (documents, medieval paintings, newspaper reports), geological and morphological documentation. The most important are the environmental sites of Morasko/Oborniki, Przełazy and Jankowo Dolne, where metallic meteorites were recognized. These meteorite falls represent a series of cosmic events: the Morasko fall was c. 5000 years BP, the Przełazy fall was c. 10000 years BP, and the age of the Jankowo Dolne fall is not fully documented.

The age of the Przełazy (Seelasgen) meteorite fall in the light of the metallic spherule content

Stankowski W., Uścinowicz G.

Acta Geologica Polonica

2011

Vol. 61, no. 1

115-124

Based on a study of the frequency and composition of the fine-grained magnetic fraction of peat profiles, the age and possible location of the Przełazy (Seelasgen) meteorite fall have been established. The impact took place at the site of the present peat-bog, south-west of the village of Przełazy. The date of the fall was estimated as the end of the Late Glacial and the beginning of the Holocene.
