2. Craton - Wikipedia

   en.wikipedia.org/wiki/Craton

   Cratons of South America and Africa during the Triassic Period when the two continents were joined as part of the Pangea supercontinent. A craton (/ ˈ k r eɪ t ɒ n / KRAYT-on, / ˈ k r æ t ɒ n / KRAT-on, or / ˈ k r eɪ t ən / KRAY-tən; [1] [2] [3] from Ancient Greek: κράτος kratos "strength") is an old and stable part of the continental lithosphere, which consists of Earth's two ...

   Approximate location of Mesoproterozoic (older than 1.3 Ga) cratons in South America and Africa. The São Luís and Luís Alves cratonic fragments are shown. Gondwana and the Kuungan orogen. Listed by modern continent and Gondwana, include:

4. Slave Craton - Wikipedia

   en.wikipedia.org/wiki/Slave_craton

   The Slave Craton includes the 4.03 Ga-old Acasta Gneiss which is one of the oldest dated rocks on Earth. [ 1 ] [ 2 ] Covering about 300,000 km 2 (120,000 sq mi), it is a relatively small but well-exposed craton dominated by ~2.73–2.63 Ga (billion years-old) greenstones and turbidite sequences and ~2.72–2.58 Ga plutonic rocks, with large ...

5. Vaalbara - Wikipedia

   en.wikipedia.org/wiki/Vaalbara

   The Kaapvaal craton is marked by dramatic events such as the intrusion of the Bushveld Complex (2.045 Ga) and the Vredefort impact event (2.025 Ga), and no traces of these events have been found in the Pilbara craton, clearly indicating that the two cratons were separated before 2.05 Ga. [10] Furthermore, geochronological and palaeomagnetic ...

6. Pilbara Craton - Wikipedia

   en.wikipedia.org/wiki/Pilbara_Craton

   The Pilbara Craton is an old and stable part of the continental lithosphere located in the Pilbara region of Western Australia. The Pilbara Craton is one of only two pristine Archaean 3.8–2.7 Ga (billion years ago) crusts identified on the Earth, along with the Kaapvaal Craton in South Africa.

7. West African Craton - Wikipedia

   en.wikipedia.org/wiki/West_African_Craton

   The oldest rocks were metamorphosed 2.9 to 2.5 billion years ago. In the Sahara it is mostly covered by more recent sediments from the Phanerozoic Eon. Further south, younger volcanic and sedimentary rocks outcrop in Ghana , Ivory Coast , and Sierra Leone , surrounded by even younger sediments laid down in the Precambrian .

   Oldest ergs develop on several cratons [13] Barramundi Orogeny (c. 1.8 Gyr) influences MacArthur Basin in Northern Australia. c. 1,780 Ma – Colorado Orogeny (1.78 – 1.65 Gyr) influences southern margin of Wyoming craton–collision of Colorado orogen and Trans-Hudson orogen with stabilized Archean craton structure

9. Paleoarchean - Wikipedia

   en.wikipedia.org/wiki/Paleoarchean

   There are only two locations in the world containing rock formations that are intact enough to preserve evidence of early life: the Kaapvaal Craton in Southern Africa and the Pilbara Craton in Western Australia. [4] The Dresser Formation is located in the Pilbara Craton, and contains sedimentary rock from the Paleoarchean Era.
