Brenner and the first colleagues determined the age of stones, analyzing radioactive isotopes in them, and then proves that the magnetization of stones does not change dramatically at some points. Monitoring its gradual changes, they can show that the entire variety area moves at a speed of tens of centimeters per year. This information is compared to the samples from Barberton's blue stone belt in South Africa, recorded and studied with the same technique, but does not show any movement.
This means that there should be some types of boundaries between these two (regions) to explain this relative motion. By definition, this is the motion of the sheets, firmly of Brenner Brenner. – Pilbara about 3.8 billion years ago has turned from average and high latitude, actually to the area of the magnetic column, perhaps close to the latitude where Spitsbergen is located today, in just a few million years. And Barberton is still in the equator, reality without moving. If the two panels move compared to each other, many processes will occur between them. This cannot be a completely local phenomenon, the geotician Robert Heisen from the Carnegie Institute in Washington said.
However, according to him, different ways of understanding about the cause of this movement are possible. This is partly due to the uncertainty of the speed of the plate, and the data may correspond to some theories of the Earth's arcs at that time.
At a minimum, this discovery implies the existence of a tectonic border, emphasizing Michael Brown from Maryland University.
At the same time, in his opinion, a movement of dog breeds is very different from the modern assists of the panels: In fact, Pilbar moves quickly to higher latitude and suddenly stops, this is not normal in any creation context.
Brown believes this corresponds to the theory that the earth's crust at the time included many small plates, moving under the influence of hot plums increasing from the melting coating. The remaining pieces of these panels, studied by Brenner and his colleagues, are useful to confirm the movement, but they only account for a small part of the bark, so they may not reflect the overall motivation of the earth.
The Brenner also found evidence of the change of the magnetic poles of 3.46 billion years ago, 200 million earlier than the previous case. Unlike a modern magnetic field, changing about one million years, at that time, the inverse happened less often – once tens of millions of years. This may indicate the completely different energy and mechanical processes of the Viking people, Mr. Brenner said.
The field from that remote time is still the theme of hot disputes – because too little data has existed to this day, Hazen commented.
I think this changes performance. This is a really important finding of the reversal in such an early period, he appreciates. This is something about the geology of the nucleus, which has not been established before.
