A typical example of the "veinlet type" azurite from Gottesegen open pit. Some mini tabular baryte and a bit of cerussite was found in these veinlets too. Found around 1990 by myself this specimen can be seen now at the Mechernich mining museum. Width of the specimen is approx. 18 to 20 cm.

The lead and copper ores of the Griesberg deposit occur disseminated as impregnations within the conglomerates and sandstones of the Middle Bunter. The interbedded strata of conglomerates and sandstones visible in the picture can be nicely seen at the eastern margin of the ancient open pit. Situation in 2007.
At the eastern margin of the most north open pit several older underground workings were cut by the more recent open pit mining. There macroscopic azurite (and less malachite, cerussite etc.) mineralization can be seen in situ as impregnations and small veinlets. Situation in 2007.
Ancient open pit at Griesberg. This rock is called the "elephant head". Guess why :-). Situation in 2007.
View of the east wall of the open pit with abundant azurite mineralization in sandstone and conglomerate of the Middle Bunter. The Pb mineralization is more restricted to the other side of the open pit at the "elephant head" where almost no secondary copper minerals are visible in situ. Situation in 2007
