| *Location* \\ | BarrierSchillig Island Schillig,shoreline, ca. 20 km north of Wilhelmshafen, North northSea coast, Lower Saxony, Germany |
| *Depositional facies* \\ | Tidal flat |
| *Provenance* \\ | This sand probably has, like most sands in the North Sea and the Baltic Sea, a long story. Weathering products Abtragungsproduktefrom desthe skandinavischenScandinavian SchildesShield (quarzreiche plutonische und metamorphe Gesteine) und 
der Mitteleuropas wurden während des Tertiärs in Norddeutschen Stränden gesammelt und aufgearbeitet, von quartärer Vereisung bedeckt, deformiert und recycelt, in periglazialen Flußläufen und Dünenfeldern gesammelt, und bei der Flutung der Nord\- und Ostsee wiederum in Strände und assoziierte Dünen inkorporiert mostly quarz-rich plutonic and metamorphic rocks) and from the the complex Mesozoic and Paleozoic geology of Central Europe were concentrated and reworked at sandy shorelines throughout the Paleogene and Neogene in northern Germany. They were covered by Quaternary glaciers, collected in periglacial streams and dune fields, and concentrated again in Holocene shorelines and dune fields during postglacial sea level rise. Many sand grains here may find themselves for the fourth or fifth time on a beach!|
| *Composition* \\ | Almost pure, limpid quartz |
| *Texture* | Medium grained, well rounded, moderately sorted. This is The high degree of textural maturity may be surprising for thethis middle to low energetic tidal sand flat but may be explained by the close relationship to eolian dunes. Also, Thethe sample might be contaminated with sand from artificially fillednourished beaches. |
