In petrology, limburgite is a dark-colored volcanic rock resembling basalt in appearance, but containing normally no feldspar. The name derives from the type locality the Limberg or the Limburg, close to Sasbach am Kaiserstuhl in Baden-Württemberg, where they occur in the well-known rock of the Kaiserstuhl. They consist essentially of olivine and augite with a brownish glassy groundmass. The augite may be green, but more commonly is brown or violet; the olivine is usually pale green or colourless, but is sometimes yellow. Within the groundmass a second generation of small euhedral augites frequently occurs; more rarely olivine is present also as an ingredient of the matrix. The principal accessory minerals are ilmenite and apatite. Feldspar though sometimes present, is never abundant, and

  • Als Limburgit wird ein Basanit (ein basaltisches Ergussgestein) mit glasiger Grundmasse und porphyrischem Gefüge bezeichnet. Der Name leitet sich von seiner Typlokalität, dem Limberg bzw. der Limburg bei Sasbach am Kaiserstuhl in Baden-Württemberg ab. Er wurde von dem Geologen Karl Heinrich Rosenbusch bereits im Jahre 1872 eingeführt. (de)
  • 玻基辉橄岩(英語:limburgite)是一種超基性暗綠色熔岩,常與鹼性玄武岩伴生。岩石具斑狀和似斑狀結構,斑晶爲橄欖石和含鈦普通輝石,基質爲黄褐色玻璃或由含鈦輝石、金屬礦物和少量斜長石組成的微晶集合體。當岩石中輝石含量超過橄欖石時可過渡爲玻基輝石岩。是橄欖岩的淺成-噴出相。主要產狀是岩床、岩牆等小侵入體,其次是玄武質熔岩下部堆晶相。主要由橄欖石(含量爲50-70%)和輝石組成。輝石多爲普通輝石、含鈦普通輝石,有時也出現、斜方輝石、、、雲母和金屬礦物,偶爾見磷灰石。玻基辉橄岩具有微晶結構、粒狀結構、嵌晶結構、填間結構等。當苦橄岩具斑狀結構時則過渡爲苦橄玢岩。 (zh)

  • Limburgit je tmavě zbarvená a částečně zesklovatělá sopečná hornina, která vzhledem připomíná čedič, ale na rozdíl od něj neobsahuje živce. Nazvaná byla podle lokality Limburg nedaleko obce v Bádensko-Württembersku, kde tvoří skalní útvar Kaiserstuhl. Obsahuje zejména minerály olivín, augit a amfibol a dále magnetit, ilmenit, apatit, nefelín a sodalit. Lokality limburgitu se vyskytují v řadě evropských zemí, např. v Německu, Skotsku, Francii nebo Španělsku. Mimo Evropu jsou známé oblasti výskytu v Brazílii nebo na africkém Kilimandžáru. V Česku se vyskytuje např. na Solanské hoře v Českém středohoří, v přírodní památce Rotava v Krušných horách nebo u pramenů Černého potoka v Mikulášovicích. (cs)

Within the groundmass a second generation of small euhedral augites frequently occurs; more rarely olivine is present also as an ingredient of the matrix. The principal accessory minerals are ilmenite and apatite. Feldspar though sometimes present, is never abundant, and nepheline also is unusual. In some limburgites large phenocrysts of dark brown hornblende and biotite are found, mostly with irregular borders blackened by resorption; in others there are large crystals of anorthoclase. Hauyne is an ingredient of some of the limburgites of the Cape Verde Islands.- Rocks of this group occur in considerable numbers in Germany (Rhine district) and in Bohemia, also in Scotland, Auvergne, Spain, Africa (Kilimanjaro) and Brazil. They are associated principally with basalts, nepheline and leucite basalts and monchiquites. From the last-named rocks the limburgites are not easily separated as the two classes bear a very close resemblance in structure and in mineral composition, though many authorities believe that the ground mass of the monchiquites is not a glass but crystalline analcite. Limburgites may occur as flows, as sills or dykes, and are sometimes highly vesicular. Closely allied to them are the , which are distinguished only by the absence of olivine; examples are known from Bohemia, Auvergne, the Canary Islands and Ireland. (en)
