Basic geological regions of Australia, by age. The geology of Australiaincludes virtually all known rock types, spanning a geological time period of over 3.8 billion years, including some of the oldest rocks on earth. Australiais a continentsituated on the Indo-Australian Plate.
By the mid-Paleozoic, the collision of North America and Europe produced the Acadian-Caledonian uplifts, and a subducting plate uplifted eastern Australia. By the late Paleozoic, continental collisions formed the supercontinent of Pangaea and created great mountain chains, including the Appalachians, Caledonides, Ural Mountains, and mountains ...
Australia was created by the junction of three early pieces of continental crust (cratons). Three areas of the Australian landmass that are made of Archaean rocks are more than 2.5 billion years old, among the oldest known rocks. These igneous and metamorphic rocks are found in the Yilgarn (West) and Pilbara (North) cratons in today's Western ...
Carboniferous. The Great Dividing Range, also known as the East Australian Cordillera or the Eastern Highlands, is a cordillera system in eastern Australia consisting of an expansive collection of mountain ranges, plateaus and rolling hills. It runs roughly parallel to the east coast of Australia and forms the fifth-longest land-based mountain ...
Mount Dandenong. Mount Dandenong (Aboriginal Woiwurrung language: Corhanwarrabul[3]) is a mountain that is part of the Dandenong Ranges of the Great Dividing Range, located in the Central District of Victoria, Australia. The mountain has an elevation of 633 metres (2,077 ft) [4] and is located approximately 45 kilometres (28 mi) east of Melbourne.
Ouachita orogeny – Mountain-building event that resulted in the Ouachita Mountains Ouachita Mountains of Arkansas and Oklahoma is an orogenic belt that dates from the late Paleozoic Era and is most likely a continuation of the Appalachian orogeny west across the Mississippi embayment – Reelfoot Rift zone.
The Ordovician (/ ɔːrdəˈvɪʃi.ən, - doʊ -, - ˈvɪʃən / or-də-VISH-ee-ən, -doh-, -VISH-ən) [ 9 ] is a geologic period and system, the second of six periods of the Paleozoic Era. The Ordovician spans 41.6 million years from the end of the Cambrian Period 485.4 Ma (million years ago) to the start of the Silurian Period 443.8 Ma.
The geological history of the Earth follows the major geological events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy). Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left ...
