How come there is a large area of Mesozoic terrain that stretches across the Atlantic Rift on top of ground younger than it?

In the original paper on Big Bang Nucleosynthesis by Alpher, Bethe, and Gamow all the elements were formed in the Big Bang. As Stellar Nucleosynthesis became popular it grabbed the creation of heavier elements. Lithium hung around for awhile, but eventually BBN took it because SN didn't want it. There is no distinct reason for larger atoms to not be primordial other than our model is tweaked to fit with other models. Our model predicts population III stars, ones made out of hydrogen and helium devoid of heavy elements, but we don't see any so our model is wrong.

Reply to How much influence does a natural satellite (like the Moon) have on the formation of continents ? by Aubin_kun
If one planet does a near miss flyby of another planet it can form one one three general types of formations; strips, bulges or holes.
The Earth has several visible strips, Mars has a clearly visible bulge and hole.
Hope that helps
