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. Alkaline lavas occur globally in subduction-related volcanic arcs. Etudions les un peu plus en détail. Alkalinize definition is - to make alkaline. Why don't libraries smell like bookstores? Alkaline lavas—mantle-derived magmas rich in alkali metals such as potassium and sodium—are commonly found in the interiors of tectonic plates, both on continents and on islands in ocean basins.Melting of metasomatic materials in the mantle lithosphere has long been conjectured to be the main source of these magmas (1, 2), but this has not been successfully simulated experimentally. How to use alkalinize in a sentence. Calc-alkaline magmas typically have more water and a higher oxygen fugacity (redox) than a tholeiite magma; leading to an early appearance of transition metal oxides (i.e. Hawaii): Ankaramite (alkali picrite), Alkali Basalt, Hawaiite, Mugearite, Benmoreite, Trachyte is discussed in Section 14.3 (see Fig. The "calc-alkaline" series of rocks was originally defined in the early 1930s on the basis of the "alkali-lime index" on a combined SiO 2 versus (Na 2 O + K 2 O) and SiO 2 versus CaO plot.

Definition of tholeiitic magma series in the Definitions.net dictionary. By definition, all igneous rock is formed from magma.. Magma is a complex high-temperature fluid substance. 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. The term ‘calc-alkaline’ stems from this characterization, but has evolved substantially away from it. Une série magmatique est une famille de roches magmatiques formées à partir d'un même magma. Le magma acide est souvent trop visqueux pour remonter à la surface, il cristallise donc le plus souvent en profondeur 3.Cela veut dire que les roches volcaniques acides (rhyolites) sont rares 3. Peacock (1931) subsequently defined four subsets of magma using the SiO 2 value at which CaO and alkali trends intersected, including a ‘calc-alkalic’ group (intersection at 56–61 wt % SiO 2).
