home / agates worldwide / Europe / Germany / Freisen Region / Leitzweiler

The fields north of Leitzweiler are famous for their distinctive and typical agates. They are showing fine banding and whitish-greyish to bluish colours. More rare for the location are pastels. Typically for this location are onyx- or so called water-level-agates. In the north-eastern part of the agate-bearing zones a common structure for agates are interchanging layers of chalcedony and phanerocristalinic quartz. This variety can produce very fine shadow-effects in the agates. Another structure is typical for this part:pseudomorphic formations from chalcedony after needle-like inclusions  (zeolithic minerals ?) . Agates from this north-eastern part are showing morphological similarities to the water-worned agates from Arenrath, about 100 km away from this place. .
