Geocache Description:

Geologische Schichten, sichtbar an einem ehemaligen Stolleneingang. Meeresablagerungen in Schichten aus dem Trias in 236m NN Höhe

Die Gegend um den Stromberg (Schengen, Luxemburg) zeichnet sich durch eine hohe Dichte an geologischen Schichten aus. Zwischen dem Moseltal (145 m NN) und dem höchsten Punkt am Plateau (315 m NN) liegen rund 170 Millionen Jahre Erdgeschichte.

Direkt neben dem ehem. Eingang befindet sich ein Infostand mit Tafeln zur Zeitgeschichte und Gesteinsproben zum Anfassen.


Macht ein Foto von euch mit GPS am Earthcache und schreibt mir die Jahreszahl vom Beginn des Gipsabbaus.

Bei richtiger Lösung gibt es die Logfreigabe!
Logeinträge ohne Lösung bzw. ohne Logfreigabe werden gelöscht!


Im Moselbett liegt die älteste Schicht, Quarzit aus der Devon-Zeit, ca. 400 Millionen Jahren. Dieser hat sich aus angestautem Sand gebildet, der sich verfestigt hat. Am Anfang des Trias vor ca. 250 Mio. Jahren war die Gegend vom Meer bedeckt, dessen Ablagerungen sich darüber gebildet haben, Trias Buntsandstein. Es folgen Schichten von Gips und Dolomit aus dem Mittleren Trias.

Das Foto zeigt den ehemaligen Eingang zum Stollen. Die Schichten haben nachgegeben und haben sich halbrund verformt in die Stollenöffnung gelegt.

Geological beds in an entrance of a former gypsum mine. Very exact sediments of a former sea, 250 Million years ago.

Today we visit the small village SCHENGEN, found in the so called 'Three Country Area' of Germany, France und Luxembourg.

At the 'Strombierg', a small mountain, you can find a very high rate of different beds. Between the river 'Mosel' at 145 m and the top of the 'Strombierg' (315 m) the time difference in the beds is about 170 million years (in 170 m) !

The oldest bed is the quartzit near the river, which is about 400 Million years of age. It became of the compressed sand of the river. 250 Million years ago this area was covered by sea, whose sediments built the next beds: bunter, gypsum and dolomite.

On the foto you can see the former entrance of the gypsum-mine, which now is blocked by beds of stone and sediments. At this place you can recognice the different beds very exact; normally they are covered with earth and vegetation.

Beside you find some info-boards with fotos, diagrams and historical facts to the theme. The different kinds of beds are exhibited by examples.

On face there are some banks and the relicts of the narrow-gauge track system.

Nearby you find some info-boards.
Please mail me the year of the beginning of the gypsum- mining and add a foto of you, your GPS and the Earthcache.
