One of the still overseen features of the Antarctica moutains formation is the strong evidence of the rest of the impact crater that has been formed 259.5 million years ago.
Two months ago NASA's Goddard Space Flight Center has announced the new results of NASA's IceBridge Mission Contributes to New Map of Antarctica. A new dataset called Bedmap2 gives a clearer picture of Antarctica from the ice surface down to the bedrock below.
At the end of the section „The antipodal correlation“ (in „Naturics“-point of the main menu), I have written:
„A quite similar antipodal correlation can be observed on the Earth`surface, as I have documented in the Naturics books. For example, the Siberian Trapps are 258 Mln years old and they are connected with a corresponding impact in Antarctica (probably in Ross Sea or Weddel Sea).“
Now we are able to see the rest of this impact crater, which the plate tectonics has left undamaged after the recent 259 million years of the Antarctic continent drift over the Earth's surface. But the evidence is still clear as shown on the NASA's pictures below. My favourite location of the crater (left after the impact 259.5 million years ago, which has produced the Siberian basalt province) has been circled with the red curve on these pictures.
I cannot imagine another geophysical event forming the sharp edge of the Antarctic crust than a huge cosmic impact of the level 8 of the Cosmic Hierarchy of our Solar System. (Compare also the cosmic timescale.)
