Siliceous shales, siliceous limestones and the so-called "siliceous transition layers" are exposed in the quarry. The latter consist of black alum shales, pebbly clay shales, limestones and tuff layers. These deposits belong to the so-called Kulm facies of the Lower Carboniferous (approx. 330 million years ago) and were formed in a constantly sinking basin on the northern edge of the rising Variscan Mountains. Fossils document the life of the Carboniferous Sea at a water depth of up to 200 meters. Shells, cephalopods and the fossilized remains of plants can be found in the almost vertically folded rock layers or in the surrounding rubble.
Age of the rocks: Kulm facies, Lower Carboniferous (around 330 million years before today)
Use of the rocks: The siliceous limestone was hewn here for house construction, the siliceous slate was crushed for road construction and used as gravel.
You will find the quarry at Bromberg on the L740 towards Küstelberg, after the turn-off to Glindfel, turn right into the parking lot after about 750 m. You will reach the quarry after about 100 m on foot.
