To my dear regular readers thank you for visiting my blog site. I have taken the liberty of autoposting a few blogs while I am undergoing surgery over the next week or so, any comments will be answered latter.
The age of the Moon is estimated to be 4.36 billion years old. Recent analysis on Moon rock samples
suggests that the Moon is much younger,about 200 million years younger.
You would think that a mere 200 million years would not make that much of a difference.
Yet the difference in the apparent age of the Moon is crucial to better understanding of how the Moon and Earth first formed in a young emerging Solar system.
New data obtained from of isotopes of lead and neodymium located in the Moon rocks samples suggests that the Moon may be younger than we think. The samples tested were ferroan anorthosite, a crust like rock that is the by product of magma.
The current most common theory is that the Moon was created by colliding with another planet type object and very young emerging Earth.The Earth then was a very different place than we know now.
The heat from the collision would have ejected large chunks of molten material into space.The material subsequently cooled forming the Moon.
These findings show that that the Moon coalesced mach later than the previous estimate mad on the Moon samples, or we have to re think our understanding of how the Moon formed from a geochemical standpoint.
If these new findings are correct it would suggest that the crust structure of the Earth and Moon were
formed at near the same time or shortly after the collision that would account for the age disparity.
Co incidentally the dating data supports that a similar age estimate obtained form samples of Quebec-zirconium found in Western Australia are the oldest terrestrial minerals found on Earth so far.
