The Barberton Greenstone Belt is located in the High Veld region and has been difficult to decypher, we are told. Standard geologys can’t make sense of the mix – or mainstream have not yet come up with a consensus. This one might do the trick.

The authors have compared the Greenstone Belt in South Africa with geology on the sea floor, just off the coast of New Zealand. As this geology is quite recent, it sounds like they might have hit the nail on the head. The Greenstone Belt goes back 3 billion years, we are told. Not so the sea floor off New Zealand. The geology there is known to have been caused by landslides – hence the mix of different rocks. These were triggered by earthquakes along the Hikurangi fault line – or subduction zone as geologists like to say. Hence, the authors make the case for ancient earthquakes in South Africa being responsible for the Greenstone Belt – in order to create the necessary landslides. Then they go on to say this means Plate Tectonics was taking place earlier than mainstream allow – 3 billion years ago. Why else would there have been a subduction zone. On the other hand, the subduction zones are theoretical – but mainstream consensus has iron clad their existence.

It formed and persisted for just four short weeks. Nowhere to be seen now. It is what is known as a polynya – and if you want to know what that is look up the Wiki.

They have found that in 3 million years old ice, going back to the Pliocene, that temperatures were a bit warmer than they are currently on the ice continent. The Pleistocene period, invented as somewhere to place the ice ages, didn’t start until 2.6 million years ago – so they are talking about late Pliocene. Analysis of Pliocene air trapped in ice cores indicates the region was several degrees warmer than today. Was this prior to the existence of an ice sheet on Antarctica?
