The Paleoproterozoic Era [4] (also spelled Palaeoproterozoic) is the first of the three sub-divisions of the Proterozoic eon, and also the longest era of the Earth's geological history, spanning from (2.5–1.6 Ga).
The Proterozoic is subdivided into three geologic eras (from oldest to youngest): the Paleoproterozoic, Mesoproterozoic and Neoproterozoic. [7] It covers the time from the appearance of free oxygen in Earth's atmosphere to just before the proliferation of complex life on the Earth during the Cambrian Explosion.
The area formed in a slow tectonic plate collision during the Paleoproterozoic era, 2.5–1.6 billion years ago . The Kimberley Craton, moving south-eastwards, collided with the North Australia Craton, resulting in a series of deformations creating the Hooper Complex and Lamboo Complex.
The Statherian Period (/ s t ə ˈ θ ɪər i ən /; Ancient Greek: σταθερός, romanized: statherós, meaning "stable, firm") is the final geologic period in the Paleoproterozoic Era and lasted from 1800 Mya to 1600 Mya (million years ago). Instead of being based on stratigraphy, these dates are defined chronometrically.
The Rhyacian Period (/ r aɪ ˈ eɪ s i. ə n /; Ancient Greek: ῥύαξ, romanized: rhýax, meaning "stream of lava") is the second geologic period in the Paleoproterozoic Era and lasted from 2300 Mya to 2050 Mya (million years ago). [2] Instead of being based on stratigraphy, these dates are defined chronometrically. [3]
The Siderian Period (/ s aɪ ˈ d ɪər i. ə n, s ɪ-/; Ancient Greek: σίδηρος, romanized: sídēros, meaning "iron") is the first geologic period in the Paleoproterozoic Era and lasted from 2500 Ma to 2300 Ma. Instead of being based on stratigraphy, these dates are defined chronometrically.
The Orosirian Period (/ ˌ ɒr oʊ ˈ s ɪər i ən /; Ancient Greek: ὀροσειρά, romanized: oroseirá, meaning "mountain range") is the third geologic period in the Paleoproterozoic Era and lasted from 2050 Mya to 1800 Mya (million years ago). [2] Instead of being based on stratigraphy, these dates are defined chronometrically.
The Huronian glaciation (or Makganyene glaciation) [1] was a period where at least three ice ages occurred during the deposition of the Huronian Supergroup. Deposition of this largely sedimentary succession extended from approximately 2.5 to 2.2 billion years ago (), during the Siderian and Rhyacian periods of the Paleoproterozoic era.
