Intrusions in Diamonds

9 April 2021

Jewellers consider intrusions in diamonds a blemish – and they fetch a much lower price than diamonds that gleam more brightly. Geologists, on the other hand, are interested in the intrusions – minerals that got into the diamonds at some point during the process that made the diamonds. It is in fact a crucial factor as far as Plate Tectonics are concerned – or could be if one or two geologists made a point of pointing out that it contradicted the mainstream geological mantra. See www.sciencealert.com/how-the-heck-did-surface-minerals-get-in-some-of-th… … a link sent in by Gary. How could surface minerals get into diamonds found in the deepest depths of the earth? Diamonds that formed hundreds of km below the surface contain traces of chemical reactions that took place at the bottom of the oceans, on the sea floor. So it would seem – or that is what we are being told. Officionados of mainstream geology theory see it as evidence of Plate Tectonics – and the process of subduction. Is it? The idea is that tectonic plates that make up the sea floor are regularly subducted – and that includes ocean water gobbled up from below. Hence, according to Plate Tectonics theory the earth recycles surface material, including water – swallowed into the Mantle. This appears to contradict a similar story last week, on the News. Here it was said such processes are a clue that water exists in the depths of the earth – prior to the onset of Plate Tectonics. It was suitably dated billions of years ago. The assumption was made by the geologists, on that occasion, that during early earth, there must have been a lot of water inside the earth – otherwise they could not have occurred. But they did. It makes sense in a way if you want to think in terms of water leaking on to the surface and making the oceans grow. In most geology text books the planet has always been watery – even during Pangaea. All the continents were bunched up but surrounded by one huge ocean of water. This of course allows uniformitarians to think in terms of multiple pangaea events – stretching into far reaches of time. At the moment there seems to be no logical alternative. However, this kind of research is pointing a finger and that may pay dividends at some point in the  future.
