With ambitious shaft projects, its own cableway connection to Bexbach, and remarkable geological features – including fossil discoveries and natural oil seepages – the mine reflects both the rise of industrial progress and the dangers of underground work. Gas explosions, water ingress, and tragic accidents shaped the lives of thousands of miners. Frankenholz remains a compelling reminder of a bygone mining era. |

Jahren. Die Kreide endet vor ca. 65,5 Mio. Jahren mit dem Übergang zum Paläozän, dem ältesten Teil des Paläogen. Die Kreide wird grob in Unterkreide und Oberkreide geteilt. Diese gliedern sich wieder in weitere Stufen. Für eine genaue Unterteilung der Kreide siehe die Geologische Zeittafel. |
