“…Previous studies have subdivided A-type granites into A1 and A2 types (Whalen et al, 1987;Eby, 1990;Pitcher, 1997). The A1 type is mantle-derived and emplaced in post-orogenic or anorogenic settings such as continental rifts or intraplate environments, whereas the A2 type is derived from partial melting of continental crust or underplated mafic crust and can be emplaced in a variety of tectonic settings.…”

“…The Strzelin intrusion shows many features typical of a sheeted granite pluton emplaced into an active fault or shear zone by injection of multiple magmatic sheets (Hutton 1992;Pitcher 1993). These features are strikeparallel, steeply inclined sheets of granite intruded into each other, relative homogeneity reflecting little petrographical differences between the granite sheets, the lack of chilled margins between the successive granites, and the presence of ''ghost stratigraphy,'' that is, the strike-parallel zone of country rocks xenoliths between the mediumgrained and fine-grained biotite granites.…”

The Strzelin Massif in SW Poland (Central European Variscides) records a protracted igneous evolution, with three main magmatic stages: (1) tonalitic I, (2) granodioritic and (3) tonalitic II/granitic. In the northern part of this Massif, the Strzelin intrusion proper comprises three successively emplaced rock types: a medium-grained biotite granite (303 ± 2 Ma), a fine-grained biotite granite (283 ± 8 Ma) and a fine-grained biotite-muscovite granite; based on field evidence, the third variety postdates both types of the biotite granites. The structural data from the three granites, including their parallel, approximately E-W striking and steeply dipping lithological contacts and ENE-WSW trending subhorizontal magmatic lineations, suggest that the emplacement of all three successive granite varieties was controlled by an active, long-lived strike-slip fault, striking ESE-WNW, with a dextral sense of movement. After the emplacement of the youngest biotitemuscovite granite, the intrusion underwent brittle extension which produced ''Q joints'' striking NNW-SSE to N-S and dipping at 55-70°WSW to W, and showing evidence of broadly N-S directed sinistral displacements. The structural observations, supported by new geochronological data, indicate that the internal structure of the composite granitoid intrusion, including the faint magmatic foliation and lineation, formed in a long-lived strike-slip setting, different from the subsequent, post-emplacement extensional tectonics that controlled the development of brittle structures.

“…Previous models have explained fayalite granitoids as granitic residual melts from the fractional crystallization of mafic magmas (i.e., Pitcher, 1997;Frost and Frost, 1997;Turner et al, 1992). Another hypothesis is that fayalite granitoids originate from partial melting of a dehydrated source, like granulites of the lower continental crust (e.g., Collins et al, 1982).…”

Fayalite granitoids of the Cobquecura Pluton, Central Chile, occur in an active continental margin setting, which is unusual for such rocks. They are closely associated with gabbros, and both lithologies contain hercynite-rich, Fe-rich metapelitic xenoliths. The primitive magmas of the Cobquecura Pluton are derived from a mafic source, similar to the regional subarc subcontinental mantle. Sr-Nd-Pb isotope data demonstrate that crustal contributions were important in the petrogenesis of the fayalite granitoids. The crustal contribution, however, does not consist of rocks similar to the regionally exposed Paleozoic basement rocks, but rather resembles partial melts derived from metapelitic rocks at depth. The corresponding restites are the hercynite-rich xenoliths. A relatively high content of rare earth elements and high field strength elements in the fayalite granitoids is linked to selective assimilation of crust. This is evident from the abundant xenoliths that are entrained in the fayalite granitoids, and whose leucosomes are rich in accessory minerals carrying these elements. Such Fe-rich rocks similar to the hercynite-rich xenoliths could have acted as a chemical buffer keeping the oxygen fugacity low, which is crucial for the generation of fayalite bearing granitoids.
