The amber ascertained in Poland occurs in Paleogene and Quaternary formations. The biggest accumulations of amber in Paleogene sediments are connected with the northern marginal zone of the Eocene Sea. In the northern zone amber has agglomerated in the sandy-silty sediments with glauconite in the Eridan river delta (the so-called chłapowsko-sambijska delta). The best documented is Chłapowo region where sediments occur on the depth between 60 and 130 m. In the southern zone of the Eocene Sea the amber-bearing sediments (silts and sands with glauconite) were also formed in the delta zone, the so-called Parczew delta. These sediments occur on the depth between 20 and 30 m. The Górka Lubartowska deposit covers the area of 295.88 ha and the average thickness of sediments is of 12 m. The third amber occurrence in Paleogene sediments is the Możdżanowo region near the Słupsk in northern Poland. The amber-bearing sediments occur on the depth about 11 m below surface.
Quaternary amber-bearing sediments are occurring mainly in chłapowsko-sambijska delta. There are two deposits documented: the Wiślinka I deposit and the Przeróbka-SL deposit. Big amber concentrations are also encountered on the Baltic beaches from Kołobrzeg to the eastern border of Poland.
Anticipated economic resources as of 31.12.2012 amounted to 1,118 tonnes of amber within four deposits: Górka Lubartowska, Możdżanowo, Wiślinka I and Przeróbka-SL.
The amount of amber collected on the Baltic beaches is estimated at several tonnes per year.
