The calculated F, and F for batch melting may yield fairly reliable results for primary magmas formed at low degrees of partial melting (Maaloe, 1994). [Pg.126]

It is generally conceded that ultramafic to mafic magmas are the products of partial melting of ultramafic rocks in the Earth s upper mantle (Kushiro, 2001 see Chapter 2.08). The composition of primary magmas generated by partial melting of ultramafic mantle rocks are, in turn, controlled by the mineralogy and chemical composition of the ultramafic rocks, as well as by the pressure, temperature, and extent of partial... [Pg.1351]

Petrologic and major element studies of Cen-ozoic continental basaltic rocks have dehned two primary magma series in intraplate basaltic igneous rocks alkalic, and tholeiitic (the latter comprising, along with calc-alkalic, the subalkalic series of Iddings (1892)). Alkalic... [Pg.1354]

Primary magmas parental to primitive andesites may also be parental to calc-aUcaline, evolved arc magmas. It is evident that fractionation of olivine, pyroxene, and/or plagioclase from a primitive andesite melt leads to higher... [Pg.1874]
