Physical properties
Hardness 3 on Mohs scale, distinct golden-yellow to ochre color, dull or earthy luster, granular crystal structure with visible fossil fragments and vugs.
Formation & geological history
Formed during the Bajocian stage of the Jurassic period through the accumulation of marine shell fragments and ooids in shallow warm seas.
Uses & applications
Extensively used as a regional building stone for historical architecture and monuments in northeastern France, particularly Metz.
Geological facts
Also known as the Stone of Metz, it gives the city's historic buildings their warm golden glow. It naturally weathers and hardens over time upon exposure to air.
Field identification & locations
Identify in the field by its characteristic golden-yellow color, porous texture, and abundance of small fossil debris. Found primarily in the Moselle department of France.
