Fansipan (Vietnamese: Phan Xi Păng, listen ⓘ) is a mountain in Vietnam. Its height was 3,143 metres (10,312 ft) in 1909, and it presently stands at 3,147.3 metres (10,326 ft). [ 1 ] It is the highest mountain on the Indochinese peninsula (comprising Vietnam, Laos , and Cambodia ), hence its nickname, "the Roof of Indochina".
The Central Atlantic magmatic province (CAMP) is the Earth's largest continental large igneous province, covering an area of roughly 11 million km 2.It is composed mainly of basalt that formed before Pangaea broke up in the Mesozoic Era, near the end of the Triassic and the beginning of the Jurassic periods.
Lake Nipissing; 8,400 – 5,500 YBP formed as the water bodies in the Superior and Huron basins merged across Sault Ste. Marie around 8,400 YBP and then merged with the Michigan basin around 7,800. [1] Lake Stanley-Hough; 8,700 YBP, the water levels had risen to connect both Lake Stanley and Lake Hough into a single body of water. [1]
In 1992, Coffin and Eldholm initially defined the term "large igneous province" as representing a variety of mafic igneous provinces with areal extent greater than 100,000 km 2 that represented "massive crustal emplacements of predominantly mafic (magnesium- and iron-rich) extrusive and intrusive rock, and originated via processes other than 'normal' seafloor spreading."
The boundary of the region where ice could form in the early Solar System is known as the frost line (or snow line), and is located in the modern asteroid belt, between about 2.7 and 3.1 astronomical units (AU) from the Sun. [24] [25] It is therefore necessary that objects forming beyond the frost line–such as comets, trans-Neptunian objects ...
[note 1] Another estimate assumes that after the first breach of the sill, the flowing water eroded the threshold and formed the channel across the Strait of Gibraltar, increasing the flow of water which in turn increased the erosion until water levels rose enough in the Mediterranean to slow the flood. [20]
The very active mid-ocean ridges associated with the breakup of Pangaea raised sea levels to the highest in the geological record, flooding much of the continents. [ 58 ] The expansion of the temperate climate zones that accompanied the breakup of Pangaea may have contributed to the diversification of the angiosperms.
The melting of ice caps and glaciers contributed to a rise in sea levels, recognizable from the fact that Silurian sediments overlie eroded Ordovician sediments, forming an unconformity. Other cratons and continent fragments drifted together near the equator, starting the formation of a second supercontinent known as Euramerica .
