This post is updated with additional information.
I am working on the Magdalenian site of Roc-aux-Sorciers. I have several blocks of limestone collected in close proximity to this site. It is located in France, in the department of Vienne. The site's parietal sculptures were made of oolitic limestone. Some of the blocks I have picked up are oolite limestones. But others do not seem to be. How would you characterize this limestone?
More informations about this block :
- Limestone, for sure. From Malm (Upper Oxfordien).
- Hardness : 3
- Color : white/beige
- The grain is fine (Very different from the grain of the oolithic limestone)
- Some small degassing bubbles.
