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.
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
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.
