The agate occurrence is settled in the older Oberhofer Quarzporphyr. For this occurrence the formation of “water-level-agates” is very typical. Most balls (lithophysae) of this occurrence lead however no agate, but macro-crystalline quartz. At these agates the strongly contrasting color change between white and brownish-red is interesting.

Further data to the place of discovery are with pure Haake, “agates collect in Germany, part 1” page 77,-78 (Bode publishing house, 2000)
