Copyright © 2021 Multiply Media, LLC. When mafic (basalt-producing) magmas crystallize, they preferentially crystallize the more magnesium-rich and iron-poor forms of the silicate minerals olivine and pyroxene, causing the iron content of tholeiitic magmas to increase as the melt is depleted of iron-poor crystals. • Peacock, M. A. The alkaline magma series is a chemically distinct range of magma compositions that describes the evolution of an alkaline mafic magma into a more evolved, silica-rich end member. sub-alkaline magma translation in English-German dictionary. • Magmas have experienced metasomatic enrichment from prior subduction. The source region is assumed to be within the lithospheric mantle. Rocks in the alkaline magma series are distinguished from rocks in the subalkaline tholeiitic and calc-alkaline magma series by their high content of alkali metal oxides (K 2 O plus Na 2 O) relative to silica (SiO 2).They are distinct from the rare peralkaline magmas, which have excess alkali oxides relative to alumina (Na 2 O + K 2 O > Al 2 O 3). The controversy dates back to the classical works by Bowen and Fenner , and it deals with the general chemical trend of evolution of sub-alkaline basaltic magma. Information and translations of tholeiitic magma series in the most comprehensive dictionary definitions resource on the web. If magmas are related to each other by some processes, that process would have to be one that causes magma composition to change. Hanson 1978, Pearce et al. The proportion of three‐dimensional structural units increases at the expense of chain and sheet units as the magma becomes more acidic. alcalin est une substance relative aux alcalis, comme des métaux alcalins.

Vérifiez la prononciation, les synonymes et la grammaire. • Magmas of the TAC formed by differentiation from lithospheric mantle melts. However, a calc-alkaline magma is oxidized enough to precipitate significant amounts of the iron oxide magnetite, causing the iron content of the magma to remain more steady as it cools than with a tholeiitic magma. The nephelinic, leucitic and analcitic series evolves from nephelinite or melilite through analcite to leucitite or wyomingite. See more. magmas (1,2), but this has not been success-fully simulated experimentally. Through those procedure the olivine tholeiitic primary magma would change to calc-alkaline magmas and more evolved and enriched alkaline or siliceous magmas. Une série magmatique est une famille de roches magmatiques formées à partir d'un même magma. Geochemistry of immobile elements is also useful to estimate tectonic settings of basaltic and granitic rocks (e.g. Now focus on the alkaline rocks that compose an extremely diverse spectrum of magmas occurring predominantly in the anorogenic portions of continental terranes * The mildly alkaline series (e.g. Oceanic crust forms at mid-ocean ridges, where tectonic plates move apart. alkaline rocks account for most of the hundreds of rocktype names in the geologic literature because of unusually great variation in chemical, mineralogical, and modal composition.

In the AFM diagram, the boundary line between the tholeiitic (TH) and calc-alkaline (CA) compositions is drawn after Irvine and Baragar (1971). Le terme adjectival alcalin, attesté en 1691 et formé sur le terme alcali ou alkali, mot latin d'origine arabe al-quâly signifiant "cendre de salicorne (qui était utilisée pour fabriquer de la soude) en ses divers sens polysémiques, peut désigner : . Ces roches évoluent selon le processus de différenciation qui peut se faire par deux mécanismes principaux : la cristallisation fractionnée et le fractionnement de basaltes [1]. Simply put, Fenner and his followers since that time have advocated a liquid differentiation trend towards strong enrichment in Fe-oxides at constant or slightly decreasing silica content. On the basis of the observed relationships between melt structure and physical properties the decreased compressibility and viscosity of basic magma compared with acidic magma may be explained. La neutralité d'un pH s'établit à 7,40 dans les cellules humaines puisqu'il s'agit du pH du sang (autrement, le neutre est établi à 7 sur une échelle allant de 0 à 14).

Such minerals may be unusually sodium rich, with a relatively high … With the calc-alkaline series, however, the precipitation of magnetite causes the iron-magnesium ratio to remain relatively constant, so the magma moves in a straight line towards the alkali corner on the AFM diagram. [3], Peralkaline rhyolites (comendite or pantellerite) may be generated by fractionation of alkali basalt magma. springer. Any process that causes magma composition to change is called magmatic differentiation.Over the years, various process have been suggested to explain the variation of magma compositions observed within small regions. Lastarria is formed by andesite dacite, both rich in potassium and characteristic of calc-alkaline magmas of the Central Volcanic Zone. 2.les différents types de séries magmatiques.

Geochemical characterization. [2], The less evolved alkali rocks tend to contain phenocrysts of olivine, and almost all have augite phenocrysts with elevated titanium, aluminum, and sodium compared with the calcic augite phenocrysts of tholeiites. Alkaline magmas are characteristic of continental rifting, areas overlying deeply subductedplates, or at intraplate hotspots. 1984, Pearce 1996). Rocks from the calc-alkaline magma series are distinguished from rocks from the tholeiitic magma series by the redox state of the magma they crystallized from (tholeiitic magmas are reduced, and calc-alkaline magmas are oxidized). (1931). Magma itself is a product of thermal and density instabilities within the mantle and crust. Alkaline definition is - of, relating to, containing, or having the properties of an alkali or alkali metal : basic; especially, of a solution : having a pH of more than 7. Alternative Title: alkalic rock Alkaline rock, any of various rocks in which the chemical content of the alkalies (potassium oxide and sodium oxide) is great enough for alkaline minerals to form.
