Onset of plate tectonics by the Eoarchean
One of the most contentious areas of Earth Science today is when, or whether or not modern-
style plate tectonics was in operation in the Archean Eon. In this review we present evidence …

Plate tectonics and the Archean Earth
If we accept that a critical condition for plate tectonics is the creation and maintenance of a
global network of narrow boundaries separating multiple plates, then to argue for plate …

[HTML][HTML] Secular change and the onset of plate tectonics on Earth
The Earth as a planetary system has experienced significant change since its formation c.

Deep formation of Earth's earliest continental crust consistent with subduction
About four billion years ago, Earth's outer layer is thought to have been composed mostly of
a 25-to 50-km-thick basaltic crust that differentiated to form the oldest stable continental …

The evolution of the continental crust and the onset of plate tectonics
The Earth is the only known planet where plate tectonics is active, and different studies have
concluded that plate tectonics commenced at times from the early Hadean to 700 Ma. Many …

Geological archive of the onset of plate tectonics
Plate tectonics, involving a globally linked system of lateral motion of rigid surface plates, is
a characteristic feature of our planet, but estimates of how long it has been the modus …

The geologic time scale
Construction and assembly of the Geologic Time Scale involves:(a) constructing a relative
(chronostratigraphic) standard scale for key periods in the Earth's rock record;(b) identifying …

Earth's continental lithosphere through time
The record of the continental lithosphere is patchy and incomplete; no known rock is older
than 4.02 Ga, and less than 5% of the rocks preserved are older than 3 Ga. In addition, there …

Recognition of ocean plate stratigraphy in accretionary orogens through Earth history: A record of 3.8 billion years of sea floor spreading, subduction, and accretion
Ocean plate stratigraphy (OPS) is a term used to describe the sequence of sedimentary and
volcanic rocks deposited on oceanic crust substratum from the time it forms at a spreading …
