最新的研究成果使人们能将马里和阿尔及利亚的泛非造山带(6亿年)解释为始于8亿年前海洋区域消失以后所发生的大陆碰撞的结果。通过对重力异常的研究可以确定西非克拉通的几何形状,并指出这种形状同异常类型之间的某种关系。人们提出了一个模式,以便解释这些观察结果。这种模式看来同样能够解释另一些前寒武纪缝合线(加拿大、巴西)的重力异常分布特征。
The latest research results allow one to interpret the Pan-African orogenic belt (600 million years) in Mali and Algeria as the result of a continental collision that began after the disappearance of the oceans by 800 million years ago. The study of gravity anomalies can determine the geometry of cocoons in West Africa and point out a relationship between this shape and the type of anomaly. People have proposed a model to explain these observations. This model also appears to explain the gravity anomalies in other Precambrian suture lines (Canada and Brazil).
