New mapping of the Barberton Greenstone Belt in South Africa shows that the central part is a pseudo-stratigraphy made of shallow-water and deep-water siliciclastic and volcanic slide blocks, with individual blocks ranging in size from tens of meters to >10 km in length. The outcrop pattern and scale are remarkably similar to those of large-scale Miocene to recent submarine landslides in New Zealand along the active Hikurangi subduction zone that are periodically triggered by earthquakes on the subduction megathrust, providing evidence for megathrust earthquakes in the Paleoarchean.

南部非洲巴伯顿绿岩带的大规模海底滑坡——古太古代俯冲和大地震的证据


南非巴伯顿绿岩带的新测绘表明，其中心部分是由浅水和深水硅质碎屑和火山滑块组成的伪地层，单个块体的大小从数十米到> 10公里不等。长度。露头的模式和规模与中新世到最近新西兰沿活跃的 Hikurangi 俯冲带发生的海底滑坡非常相似，这些滑坡是由俯冲巨型逆冲断层上的地震周期性触发的，为古太古代发生大型逆冲断层地震提供了证据。
