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".
This sedimentary unit is thought to have formed within hours of impact. [24] A 2020 study concluded that the Chicxulub crater was formed by an inclined (45–60° to horizontal) impact from the northeast. [25] The site of the crater at the time of impact was a marine carbonate platform. [26]
Walther's law of facies, or simply Walther's law, named after the geologist Johannes Walther, states that the vertical succession of facies reflects lateral changes in environment. Conversely, it states that when a depositional environment "migrates" laterally, sediments of one depositional environment come to lie on top of another. [ 4 ]
The giant Norilsk-Talnakh nickel–copper–palladium deposit formed within the magma conduits in the most complete part of the Siberian Traps. [27] It has been linked to the Permian–Triassic extinction event, which occurred approximately 251.4 million years ago, [ 18 ] based on large amounts of nickel and other elements found in rock beds ...
The Zanclean flood caused a major change in the environment of the Mediterranean basin; the continental "Lago Mare" facies was replaced by Zanclean deep sea deposits. [7] The flood may have affected global climate, considering that the much smaller flood triggered when Lake Agassiz drained did result in a cold period. [ 50 ]
The geology of Vietnam is divided into five structural blocks : Northeast (NE), Northwest (NW), Truongson, Kon Tum and Nambo. The NE block is a part of the South China plate, in which strata and igneous rocks have been found dating from the Early Paleozoic to the Quaternary. The NW and Truongson blocks are regarded as NW-SE trending Paleozoic ...
A geologic cross section of the Grand Canyon. [ 5 ] The Tonto Group is a name for an assemblage of related sedimentary strata , collectively known by geologists as a Group , that comprises the basal sequence Paleozoic strata exposed in the sides of the Grand Canyon.
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.
