About: Gregoryite

An Entity of Type: mineral, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Gregoryite is an anhydrous carbonate mineral that is rich in potassium and sodium with the chemical formula (Na2,K2,Ca)CO3. It is one of the two main ingredients of natrocarbonatite, found naturally in the lava of Ol Doinyo Lengai volcano, the other being nyerereite. Because of its anhydrous nature, gregoryite reacts quickly with the environment, causing the dark lava to be converted to white substance within hours.

dbo:abstract
  • La gregoryita és un mineral de la classe dels carbonats. Rep el seu nom del professor John Walter Gregory (1864–1932), de les universitats de Melbourne i Glasgow, qui va completar els primers estudis científics sobre l'activitat volcànica i l'estructura del sistema del Rift d'Àfrica. (ca)
  • Gregoryit ist ein sehr selten vorkommendes Mineral aus der Mineralklasse der „Carbonate und Nitrate“ (ehemals Carbonate, Nitrate und Borate). Es kristallisiert im hexagonalen Kristallsystem mit der idealisierten chemischen Zusammensetzung Na2(CO3), ist also chemisch gesehen ein Natrium-Carbonat. Gregoryit findet sich in Form von verrundeten Kristallen (Porphyroklasten) bzw. Phänokristen in einem Natrokarbonatit. Die Typlokalität des Gregoryits ist der weltweit einzige aktive Karbonatit-Vulkan Ol Doinyo Lengai (Koordinaten des Vulkans Ol Doinyo Lengai) im Distrikt Ngorongoro in der Region Arusha im nördlichen Tansania.

Because of its anhydrous nature, gregoryite reacts quickly with the environment, causing the dark lava to be converted to white substance within hours. Gregoryite was first described in 1980 and named after the British geologist and author John Walter Gregory (1864–1932), who studied the East African Rift Valley. It occurs associated with nyerereite, alabandite, halite, sylvite, fluorite and calcite. (en)

  • 格碳鈉石(英語:Gregoryite)是一種無水碳酸鹽礦物,富含鉀和鈉 。 化學式為(Na2,K2,Ca)CO3。它是鈉碳酸鹽的兩種主要成分之一,在Ol Doinyo Lengai 火山的熔岩中被發現過,另一種是尼雷爾石。 由於其無水性質,格碳鈉石與環境迅速反應,導致深色熔岩在數小時內轉化為白色物質。 1980 年格碳鈉石首次被發現,並以研究東非大裂谷的英國地質學家和作家 John Walter Gregory (1864–1932) 的名字命名 . 它與尼雷爾石、硫锰矿、石鹽、鉀鹽、螢石和方解石共生。 (zh)
