rock with 30 to 70% Ne. Melteigite contains more than 70% mafic minerals and less than 30% nepheline. Alkaline rocks are more common in volcanic and hypabyssal facia, and less abundant as plutonic rocks. Their rock-forming minerals are nepheline, feldspar, clinopyroxene, amphibole, micas, olivine, leucite, melilite. Note that neither quartz norFile Size: KB.

The "calc-alkaline" series of rocks was originally defined in the early s 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, Cited by:

Written By: 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. Such minerals may be unusually sodium rich, with a relatively high . calc-alkaline suite of rocks is abundant along destructiv e plate margins, but calc-alkaline geochem- istry is not a % foolproof indicator of subduction processes, inas much as calc-alkaline. The "calc-alkaline" series of rocks was originally defined in the early s on the basis of the "alkali-lime index" on a combined SiO2 versus (Na2O + K2O) and SiO2 versus CaO plot. For example, alkaline rocks that form the ˜ Ma (Hoatson and Claoué-Long, ) Mordor Complex in the Northern Territory range in composition from pyroxenite to syenite (Hoatson and Claoué-Long, ), and alkaline magmatic rocks include kimberlites and related rocks, and carbonatites (igneous rocks with more than 50% modal carbonate).
