In the Mars sub-section of 'The Visible Earths' section of this website, I have outlined a basic morph between the present crustal magnetic pattern and tectonic features of this Earth, and those of Mars, based on continuing the pattern of crustal movement particular to my expansion model, beginning in Central America and spanning outwards. You will find this in the 'Visible Earths' sections 1 through 16.

NOTE: The general time period of the following sequence is from the turn of the Siderikan era - 4 billion years ago to between 5 and 3.5 million years ago.

The basic ideas are as follows: ( The following 3 sections are repeated in the Mars sub-section of 'The Visible Earths' )

During the contraction stage, the extensional plates of the Pacific, and the extensional fault line of the Atlantic, continue to spread. Simultaneously, the reduction in the size of the sphere causes this spreading to further increase the pressure on plate-boundaries.

The pressure of the compressional areas around the Ring of Fire cause new and more widespread volcanic and seismic activity, and the resulting natural disasters, to begin to obscure much of the original continents. Australia, Antarctica and Asia, now collided and shredded, pile up to eventually become Syrtis Major, just above the equator of Mars.
