Arenrath

1. Formation of pseudomorphic structures of Chalcedony after low-temperature Calcite (thin tabular crystals).

- Size and structure of the pseudomorphic structures in both specimen are similar

2. Formation of shadow-effect and its distortion by the formation of small spherulithical aggregates.

- The density of interchanging transparent and opaque layers of chalcedony are similar. Size and position of the spherulithical aggregates are nearly the same.

3. Formation of spherulithical structures, of the agate-banding and needle-like structures.

- The formation of spherulithical aggregates and the agate-banding are equal in both specimen. Needle-like structures are missing in the specimen from Leitzweiler.

4. Formation of spherulithical structures, needle-like inclusions and yellowish pigmentation.

- The spherulithical structures are different in both specimen. The needle-like inclusions are better defined in the specimen from Leitzweiler. The yellowish pigmentation is equal in tone and structure.

Both locations are offering typical and very similar specimen. One difference is always the general colorization of the specimen: Leitzweiler agates are always pinkish and the agates from th River Mosel are showing grey tones. But the structural similarity of both locations is evident - Agates from Leitzweiler were transported to the gravel deposits of Arenrath and Binsfeld.

On the other hand: A lot of typical River Mosel agate-types don´t have a twin between the agate-types from Leitzweiler. There must be more than one origin for these agates.
