Igneous Petrogenesis A Global Tectonic Approach
In terms of Figure 1.2a, volcanic rocks may be subdivided into members of two
major magma series, alkalic and sub-alkalic, separated by the solid line in this
diagram. Such a division was first proposed by Iddings in 1892 and elaborated
upon ...

The across-arc variation in K2O content is observed both for calc-alkalic (CA) and
tholeiitic (TH) rocks. Compositions of continental crust are from Taylor &
McLennan (1985), Christensen & Mooney (1995) and Rudnick & Fountain (1995)

The pressure dependence of elastic-wave velocities for tholeiitic and alkalic
basalt, gabbro, periodotite, dunite, and harzburgite is controlled by the
progressive closure of microfractures with increasing depth in volcanic systems.

U.S. Geological Survey Professional Paper
Chemically, Early Proterozoic plutonic rocks range from calcic to alkalic. No
progression with time is noted, except that some of the gabbroic rocks, which are
early in the sequence, are calcic. The rocks range from aluminous to
peraluminous.
