Geocache Description:

Im Gegensatz zu allen anderen großen Bergen des Bayerischen und Oberpfälzer Waldes ist das Osser-Massiv aus Glimmerschiefern und Quarziten aufgebaut. Bei der Bildung dieser Gesteine herrschten andere Bedingungen als bei den sonst vorherrschenden Graniten und Gneisen.
Sie entstanden aus tonigen Ablagerungen, die unter hohen Temperaturen und Drucken im Erdinneren umgewandelt wurden.

Füge deinem Log bitte noch ein Foto von dem Platz bei, der die hier am besten gefallen hat.

In welcher Tiefe erfolgte die metamorphe Umwandlung der Gesteine zu Glimmerschiefern und Quarziten?

In contrast to all other big mountains in the Bavarian and Upper Palatinate Forest the Osser crag consists of mica slate and quartzites. The conditions at the time of creation of this stones were different from those of the other predominant granites and gneisses.
They arised from argillaceous deposition which where transformed under high temperature and pressure in the interior of the earth.
