Over time, rocks weather due to the influence of wind, water, ice, and daily and seasonal temperature differences. These weathering products form then short the pedosphere (the ground), go into solution in water (chemistry), are transported as dust, and similar processes. Long term, but they rearrange stable, lithify and form sedimentary rocks, are transported into the deep, and after transformation (metamorphosis) reveal pushed back ...

Geologen sprechen von einer Schichtquelle. Von hier oben genießt man den Blick über das Dorf und die Kirkeler Burg. Auf unserem weiteren Weg erreichen wir bald den Frauenbrunnen, eine weit und breit bekannte Quelle. Etwa 50 m oberhalb beginnt in östlicher Richtung der geologische Lehrpfad, entstanden 1983. Am Anfang des Weges wurde eine Übersichtskarte aufgestellt, die das Saarland, sowie angrenzende Teile geologisch umfaßt und die Fundorte der aufgestellten Steine anzeigt... |

The mine complex extends over 21.2 square kilometers and is one of the largest gold deposits in Europe. The tunnel system in the underground is several hundred kilometers long and was used until a few years ago. Already in Roman times the tunnels had a length of 145 km. |

Olivine belongs to the olivin-groupe whose end-members are calcio-olivine and tephroite. Forsterite is a magnesium silicate; fayalite an iron silicate. If commonly is spoken of olivine, it is usually a more or less iron-rich forsterite. The color of olivine is generally yellowish green, olive green to black. You will find much more interesting details in our portrait about this common mineral series. Written and investigated by Peter Seroka. (Article in german) |
