Clarens
Description
Source: Wikipédia
La formation de Clarens est une formation géologique qu'on peut trouver en plusieurs endroits du Lesotho et dans les provinces de l'État libre, du KwaZulu-Natal et du Cap-Oriental en Afrique du Sud. C'est la formation sommitale du groupe de Stormberg, lui-même composante du supergroupe du Karoo ; elle correspond à la phase finale de sédimentation du bassin du Karoo.
