Is Jurassic limestone harder than carboniferous limestone?

Jurassic limestone is generally considered to be harder than Carboniferous limestone due to differences in their formation processes and mineral content. Jurassic limestone often contains more calcite and has undergone different geological processes that can increase its hardness. However, the specific hardness can vary depending on the local conditions and the exact composition of the limestone in question. Overall, while there are general trends, it's essential to evaluate individual samples for precise comparisons.
