At https://phys.org/news/2026-04-huge-tectonic-boundary-shook-ground.html … scientists have discovered a Jurassic era tectonic plate boundary near the coast of Mazambique and Tanzania, stretching over 500 km [as currently assessed]. It is the boundary between Africa and the Indian Ocean in the modern world but it appears to have split asunder Gondwanaland. It is thought to have formed in the Jurassic period. We are told it marks where two tectonic plates ripped themselves apart. We may note this idea strongly conforms to the dominant Plate Tectonic theory – on the assumption Pangea, the single form of all the continents joined together, was split up at that time. Between the Triassic, Jurassic and the Cretaceous – thereafter slowly moving apart endlessly until the present day. In order to keep this theory alive we now have a succession of Pangea like rearrangements of earth’s continents prior to the Triassic era.
What of an alternative view. The only other geological theory that would seem to also fit the facts of a dismantling of Pangea is the Expanding Earth theory. We may note that all the facts used to support the idea of plate tectonics creating fractures in Earth’s crust, could also be applied to the Expanding Earth – including ever widening ocean basins. It also seems relevant to point out these big shifts in plates, or faults, occur mostly contemporary with boundary events, and therefore, with catastrophism. If that is your bend of mind. The end of Triassic period, for example, end of Jurassic and end of Cretaceous. That is one way of looking at the geochronology. However, if the geology associated with those extinction events was laid down quickly there would be an awful lot of geology that was missing – including the never ending slow process of continental drift or the necessary evidence that Earth was expanding. The question then becomes – what would make the Earth expand at specific points in time, or what would cause the plates, unknown anywhere else in the solar system, to move?
The link ends by noting that small fragments of the former Gondwana Land have been stranded in the Indian Ocean. One would only have to think in terms of the Chagos Islands, the Seychelles, or Mauritius.
