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".
Terraces can be formed in many ways and in several geologic and environmental settings. By studying the size, shape, and age of terraces, one can determine the geologic processes that formed them. When terraces have the same age and/or shape over a region, it is often indicative that a large-scale geologic or environmental mechanism is responsible.
Franciscan rocks are thought to have formed prior to the creation of the San Andreas Fault when an ancient deep-sea trench existed along the California continental margin. This trench, the remnants of which are still active in the Cascadia and Cocos subduction zone, resulted from subduction of oceanic crust of the Farallon tectonic plate ...
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 ...
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.
Rock layers of the Moenkopi Formation in Zion National Park. The Moenkopi Formation is a geological formation that is spread across the U.S. states of New Mexico, northern Arizona, Nevada, southeastern California, eastern Utah and western Colorado.
Geologists can also determine the movement of continental plates by examining the orientation of magnetic minerals in rocks. When rocks are formed, they take on the magnetic orientation of the Earth, showing which direction the poles lie relative to the rock; this determines latitudes and orientations (though not longitudes).
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 ...
