Kuno Peak
Kuno Peak is a mountain peak in the Spectrum Range at the southern end of the Mount Edziza volcanic complex in northwestern British Columbia, Canada. It is south of Yagi Ridge, west of Yeda Peak, southeast of Outcast Hill, east of Exile Hill, northeast of Tadekho Hill and north of Little Arctic Lake, the latter four of which are on the northern end of the Arctic Lake Plateau. It has an elevation of and lies at the southwestern end of the Spectrum Range. Tadekho Creek originates from the southern flank of the ridge connecting Kuno Peak with Yeda Peak. Kuno Peak is at the south end of Mount Edziza Provincial Park which is southeast of the community of Telegraph Creek. It is named after Hisashi Kuno, a Japanese volcanologist and teacher who visited the area with Canadian volcanologist Jack Souther in 1966. The name of the peak became official on January 2, 1980, after being submitted to the BC Geographical Names office by the Geological Survey of Canada. Geology Kuno Peak is for ...

Trachyte
Trachyte () is an extrusive igneous rock composed mostly of alkali feldspar. It is usually light-colored and aphanitic (fine-grained), with minor amounts of mafic minerals, and is formed by the rapid cooling of lava enriched with silica and alkali metals. It is the volcanic equivalent of syenite. Trachyte is common wherever alkali magma is erupted, including in late stages of ocean island volcanismMacDonald 1983, pp. 51-52 and in continental rift valleys, above mantle plumes,Philpotts and Ague 2009, pp. 390-394 and in areas of back-arc extension. Trachyte has also been found in Gale crater on Mars. Trachyte has been used as decorative building stone and was extensively used as dimension stone in the Roman Empire and the Republic of Venice. Chemical composition Trachyte has a silica content of 60 to 65% and an alkali oxide content of over 7%. This gives it less SiO2 than rhyolite and more (Na2O plus K2O) than dacite. These chemical differences are consistent with the posi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantellerite
Pantellerite is a type of volcanic rock, specifically a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite. It is named after Pantelleria, a volcanic island in the Strait of Sicily and the type location for this rock. On Pantelleria the rock is usually found as a vitrophyre containing phenocrysts of anorthoclase or sanidine. Quartz is found only in the most strongly peralkaline rocks. Mafic minerals may include aegirine, fayalite, aenigmatite, ilmenite, and sodic amphibole (often arfvedsonite or ferrorichterite).

Comendite
Comendite is a hard, peralkaline igneous rock, a type of light blue grey rhyolite. Phenocrysts are sodic sanidine with minor albite and bipyramidal quartz. Iddings, Joseph Paxson, 1913, ''Igneous rocks: composition, texture and classification'', v. 2, pp. 94-96 Comendite occurs in the mountains Tibrogargan, Coonowrin, Tunbubudla, Coochin, Saddleback, Tibberoowuccum and Ngungun in the Glass House Mountains, South East Queensland, Australia. The blue colour is caused by very small crystals of riebeckite or arfvedsonite. Comendite also occurs in Sardinia, Corsica, Ascension Island, Ethiopia, Somalia and other areas of East Africa. The 1903 eruption of Changbaishan Paektu Mountain (), also known as Baekdu Mountain and in China as Changbai Mountain ( zh, s=长白山, t=長白山; Manchu: Golmin Šanggiyan Alin), is an active stratovolcano on the Chinese–North Korean border.

Volcanic Rock
Volcanic rock (often shortened to volcanics in scientific contexts) is a rock formed from lava erupted from a volcano. In other words, it differs from other igneous rock by being of volcanic origin. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks. For these reasons, in geology, volcanics and shallow hypabyssal rocks are not always treated as distinct. In the context of Precambrian shield geology, the term "volcanic" is often applied to what are strictly metavolcanic rocks. Volcanic rocks and sediment that form from magma erupted into the air are called "volcaniclastics," and these are technically sedimentary rocks. Volcanic rocks are among the most common rock types on Earth's surface, particularly in the oceans. On land, they are very common at plate boundaries and in flood basalt provinces.

Jack Souther
Jack Gordon Souther (April 25, 1924 – June 1, 2014) was an American-born Canadian geologist, volcanologist, professor and engineer. He contributed significantly to the early understanding of recent volcanic activity in the Canadian Cordillera. Many of his publications continue to be regarded as classics in their field, even now several decades after they were written. Biography Jack Souther was born in Chicago, Illinois, United States on April 25, 1924. As a young child he moved to the U.S. state of Alabama. In his teenage years, Souther relocated with his family to the Canadian province of Alberta at a cattle ranch near the First Nations settlement of Morley. After his family lost the ranch, Souther moved with his family to the mountain town of Banff. Here, he attended Banff High School. In 1945 at the age of 21, Souther graduated as the class president. He was later accepted into a geological engineering program at the University of British Columbia in Vancouver. He was o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanologist
A volcanologist, or volcano scientist, is a geologist who focuses on understanding the formation and eruptive activity of volcanoes. Volcanologists frequently visit volcanoes, sometimes active ones, to observe and monitor volcanic eruptions, collect eruptive products including tephra (such as ash or pumice), rock and lava samples. One major focus of inquiry in recent times is the prediction of eruptions to alleviate the impact on surrounding populations and monitor natural hazards associated with volcanic activity. Geologists who research volcanic materials that make up the solid Earth are referred to as igneous petrologists. Etymology The word ''volcanologist'' (or ''vulcanologist'') is derived from the English volcanology (volcano + -logy), which was derived from the French volcanologie (or vulcanologie), which was further derived from the French word volcan (volcano), which was even further derived from Vulcanus, the Latin name of the Roman god of fire and metalworking ...

Hisashi Kuno
was professor at the Institute of Geology, University of Tokyo. He was first son of Kamenosuke Kuno (a painter of the Japanese classical school) and Tome Kuno. Life There was a field excursion after the 1930 North Izu earthquake southwest of Tokyo. This resulted that his life work (the rest 40 years) was the petrology of the Izu-Hakone region, the basaltic magmas and the crystallization of pyroxenes. He graduated at University of Tokyo (former Tokyo Imperial University) in 1932 and became assistant professor in 1939. He was drafted into the army during World War II in July 1941. He was stationed in the Manchuria and he could study the geology and mineralogy of pegmatites and several basalt plateaus there. He received his doctor of science in 1948. He visited the United States in 1951–52 and worked with professor Harry H. Hess at Princeton University. He was appointed professor of the Institute of Geology in 1955.
