DYNAMIC GEOLOGICAL TIME SCALE

The current broad geological time scale identifies the following Era, in ascending order:

GEOLOGICAL TIME SCALE

Period (My)

Interval(My)

Era

-4550 -3000 1550 Precambrian - Katarchean
-3000 -2500 500 Precambrian - (Late) Archean
-2500 -650 1850 Precambrian - Proterozoic
-650 -280 370 Paleozoic
-280 -63 217 Mesozoic
-63 -Present 63 Cenozoic

Major dynamic events occurred during this time scale. These are included with the current essay logic to define the following Dynamic Stages:-

Dynamic Stages

Events

-4550 Accretion Solidification of proto-earth. Solar & nuclear heating. Rapidly rising planet temperature.
-4400 Eye Moon/Earth separation. Upwelling lava activity on Moon. Formation of Fe-rich planet rings. Molten Earth surface. Strong Eye activity. Giant planet phase.
-3800 Vortex Decay of Fe-rich planet rings. End of intense cratering period. Proto Continental formation begins with small short-lived islands of crustal float positioned over the turbulent Vortex.
-3500 Solidus Start of stable greenstone formations. Primitive anaerobic life forms. Minor cloud condensation
-3400 Projectile Start of kinetic pipe activity. Formation of Si-rich planet rings
-3300 Terrafirma Dominant greenstone formation with granite understorey. Igneous placement - Cu,Ni,Fe,Au&Cr. Basin settling combined with igneous infill.
-3200 " Moon becomes tectonically inactive.
-2900 " Massive cloud condensation. Major sedimentation period. Rapid magma cooling & crustal coast extension.
-2800 Occlusion End of giant planet phase

" Climax formation of Proto Continent
-2700 " Convection current direction reverses below the Proto Continent.
-2550 Decompose Proto Continent uplift and more rapid erosion.
-2300 " The Proto Continent splits into several sub continents. Extensive shallow seas form.
-2000 " Fee oxygen accumulating at sea
-1900 Adhesion Start of second continent stage (Wopmay Orogeny, Canada)

Supercontinent - one land mass.

-1200 " Start of third continent stage. Extensive shallow seas form.
-700 Drift Start of fourth continent stage

" Soft bodied marine animals flourish.
-600 " Separate continents: North America, Europe, Asia:a,b & c, and Gondwanaland.
-500 " End kinetic pipe activity.
-430 " Ice age - I
-400 " Ice age - II.
-400 " North America-Europe-Asia:a rejoin, Asia:b & c, Gondwanaland, Tethys Sea formed.
-285 " Ice age - III
-280 " All continents combined into Pangaea with Tethys Sea.
-170 " Eurasia, North & South America, Antarctica/Australia, Africa, India, Tethys Sea gone.
-60 " Eurasia/India, North & South America, Antarctic, Australia, Africa.
-15 " Ice age - IV

The Dynamic Geological Time Scale raises some interesting possibilities in applying the time scale to other planets of super critical mass.
