The Elzevir batholith belongs to a suite of trondhjemitic intrusions emplaced at ca. 1,240 Ma in the Grenville Province of eastern Ontario. New major and trace element data, including REE, combined with isotopic and petrographic data indicate that:
  1. 1)

    the batholith has calc-alkalic affinities;

  2. 2)

    the Elzevir parental magma is very similar to that of dacites in the nearby, coeval metavolcanic rocks; the magma formed by partial melting of crustal material at granulite grade;

  3. 3)

    chemical differences between the plutonic and volcanic rocks can be best explained by accumulation of plagioclase in the plutonic environment;

  4. 4)

    fractionation was dominated by plagioclase and quartz, with lesser biotite and epidote, and minor zircon and apatite.


It is suggested that melting of sialic crust took place during the ‘docking’ of a partly-evolved, originally ensimatic arc system against the main cratonic mass to the northwest.
