Little is known about the paleogeography before the formation of Rodinia. Paleomagnetic and geologic data are only definite enough to form reconstructions from the breakup of Rodinia [17] onwards. Rodinia is considered to have formed between 1.3 and 1.23 Ga and broke up again before 750 Ma. [18] Rodinia was surrounded by the superocean Mirovia.
Pangaea's supercontinent cycle is a good example of the efficiency of using the presence or lack of these entities to record the development, tenure, and break-up of supercontinents. There is a sharp decrease in passive margins between 500 and 350 Ma during the timing of Pangaea's assembly.
Laurasia and Gondwana were equal in size but had distinct geological histories. Gondwana was assembled before the formation of Pangaea, but the assembly of Laurasia occurred during and after the formation of the supercontinent. These differences resulted in different patterns of basin formation and transport of sediments.
The phrase was originally said by Captain James T. Kirk (William Shatner) in the original Star Trek series. "Where no man has gone before" is a phrase made popular through its use in the title sequence of the original 1966–1969 Star Trek science fiction television series, describing the mission of the starship Enterprise.
The continents that had drifted away from Rodinia drifted together again during the Paleozoic: Gondwana, Euramerica, and Siberia/Angara collided to form the supercontinent of Pangea during the Devonian and Carboniferous periods, some 350 million years ago. Pangea was a short-lived supercontinent; it began to break apart again in the early ...
The Kirk-era part of Star Trek Generations is set 78 years before 2371 (established by way of an on-screen caption), thus is set in 2293 and soon after Star Trek VI. The gap between the 1986 film Star Trek IV: the Voyage Home (2286) and the 1987 first season of The Next Generation (2364) is 78 years by this timeline, matching early press materials.
The supercontinent Rodinia began to break up 870–845 Ma probably as a consequence of a superplume caused by mantle slab avalanches along the margins of the supercontinent. In a second episode c. 750 Ma the western half of Rodinia started to rift apart: western Kalahari and South China broke away from the western margins of Laurentia ; and by ...
Inspired by Gulliver's Travels, [6] [7] Star Trek ' s main focus is on space exploration and a galactic society consisting of multiple planets and species, where conflict occasionally occurs. Most of Star Trek occurs in the relatively distant future, specifically the 22nd through 24th centuries, with occasional time travel and interdimensional ...
