Place · people · evidence
Origin is both geological and documentary: where a stone formed, where it was recovered and what evidence follows it to market.
Reviewed
This origin library begins with Nasarawa and Nasarawa Eggon because credible published information is available. We do not create locality pages simply to occupy search results.
New pages will be added when research, photographs, interviews or specimen records make them genuinely useful.
