Mars is Pangaea: Continental/Oceanic Crust Evidence
March 13, 2013 in Science
“Mars has a diameter about as wide as the continent of Africa. Its overall size, or surface area, is about eight times less than Earth’s, but it has the same amount of dry land.”
“The average thickness of the planet’s crust is about 50 km (31 mi), with a maximum thickness of 125 km (78 mi).”
“The continental crust is typically from 30 km (20 mi) to 50 km (30 mi) thick and is mostly composed of slightly less dense rocks than those of the oceanic crust.”
“The Earth has probably always had some form of basaltic crust, but the age of the oldest oceanic crust today is only about 200 million years. In contrast, the bulk of the continental crust is much older.”
“The average age of the current Earth’s continental crust has been estimated to be about 2.0 billion years. Most crustal rocks formed before 2.5 billion years ago are located in cratons.”
It is well known “Pangaea” began to rift 200 million years ago. That is when Mars began to expand into becoming Earth, the first direct evidence of sea floor crust appearance.
Before 2.5 billion years ago was proto-earth stage #3 Ganymede: the largest satellite in the solar system.
