  • Alkaline: Definition, Medical Uses, Side Effects

     · Alkaline Definition. In pure water, a small portion of the molecules lose one hydrogen from the H2O structure, in a process called dissociation. The water thus contains a small number of hydrogen ions, H+, and residual hydroxyl ions, OH-. There is an equilibrium between the constant formation and dissociation of a small percentage of water ...

  • Mineralogical Diversity of Alkaline Igneous Rocks ...

    INTRODUCTION. Alkaline igneous rocks contain either (1) modal feldspathoids or alkali amphiboles or pyroxenes or (2) normative feldspathoids or acmite (Le Maitre, 2002).Based on the molar ratios of Na 2 O + K 2 O relative to Al 2 O 3, they can be subdivided into metaluminous [(Na 2 O + K 2 O) < Al 2 O 3 < (CaO + Na 2 O + K 2 O)] and peralkaline [(Na 2 O + K 2 O) > Al 2 O 3] types.

    Alkaline rocks form an expansive category of igneous rocks. Using a broad definition, alkaline rocks are deficient in SiO 2 relative to Na 2O, K 2O, and CaO (Winter, 2001). Two of the most important subclasses of alkaline rocks with respect to REE deposits are carbonatites and peralkaline rocks.

    the alkaline rocks are not, in their origin, distinct from the sub-alkaline rocks, but rather that both types are products of the differentiation of a common primary magma, the alkaline rocks requiring for their development certain favoring environ-mental conditions.

  • What Is the "Calc-alkaline Rock Series"?: International ...

    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. The usage of the term has evolved considerably since, and today it is used variably for the subalkalic basaltandesite-dacite-rhyolite suite, or any rock suite containing andesite, or island-arc rocks, or ...

  • Peralkaline rock

    Peralkaline rocks include those igneous rocks which have a deficiency of aluminium such that sodium and potassium are in excess of that needed for feldspar.The presence of aegerine (sodium pyroxene) and riebeckite (sodium amphibole) are indicative of peralkaline conditions.Examples are the peralkaline rhyolites, comendite and pantellerite, with comendite being the more felsic (silica-rich) rock.
