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 geology of Finland is made up of a mix of geologically very young and very old materials. Common rock types are orthogneiss , granite , metavolcanics and metasedimentary rocks. On top of these lies a widespread thin layer of unconsolidated deposits formed in connection to the Quaternary ice ages , for example eskers , till and marine clay .
The Precambrian includes approximately 90% of geologic time. It extends from 4.6 billion years ago to the beginning of the Cambrian Period (about 539 Ma).It includes the first three of the four eons of Earth's prehistory (the Hadean, Archean, and Proterozoic) and precedes the Phanerozoic eon.
At this time, geology became its own entity in the world of natural science. It was discovered by the Christian world that different translations of the Bible contained different versions of the biblical text. The one entity that remained consistent through all of the interpretations was that the Deluge had formed the world's geology and geography.
Décollement formation in an extensional setting. Décollements can form from high angle normal faults. Uplift in a second stage of extension allows the exhumation of a metamorphic core complex. A half graben forms, but stress orientation is not perturbed due to high fault friction. Next, elevated pore pressure (Pp) leads to low effective ...
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 ...
Sedimentary rocks are formed through the gradual accumulation of sediments: for example, sand on a beach or mud on a river bed. As the sediments are buried they get compacted as more and more material is deposited on top. Eventually the sediments will become so dense that they would essentially form a rock. This process is known as lithification.
An example of such texture, related to fractioned crystallization, is intergranular (also known as intercumulus) textures that develop wherever a mineral crystallizes later than the surrounding matrix, hence filling the left-over interstitial space. Various oxides of chromium, iron and titanium show such textures, such as intergranular chromite ...
