The geology and petrogenesis of the southern closepet granite [PDF]
The Archaean Closepet Granite is a polyphase body intruding the Peninsular Gneiss Complex and the associated supracrustal rocks. The granite out-crop runs for nearly 500 km with an approximate width of 20 to 25 km and cut across the regional metamorphic ...

A propos des migmatites pyreneennes
Bulletin de la Société Géologique de France, 1956 Abstract Observations in the Saint-Barthelemy massif (France) and in other localities in the Pyrenees indicate that metasomatic enrichment in silica and soda (of the order of some 5 to 10 percent) caused alteration of schists into migmatites characterized by a quartz diorite composition.

Resetting and closing codition of Rb-Sr whole-rock isochron system: some samples of metamorphic and granitic rocks from the Gondwana super-continent and Japan Arc [PDF]
, 2003 The closure temperature of the Rb-Sr whole-rock system for felsic rocks has been generally considered to be ca. 700゜C, but it falls to ca. 400゜C, as a result of efficient action of fluids,especially H_2O.

Metamorphism and plutonism in the Quetico Belt, Superior Province, N.W. Ontario [PDF]
The Quetico Belt lies between the metavolcanic Wawa-Shebandowan and Wabigoon Belts. It consists of marginal metasedimentary rocks and central pelitic, gneissic and plutonic rocks.

Correlations and contrasts in structural history and style between an Archaean greenstone belt and adjacent gneiss belt, NE Minnesota [PDF]
An analysis of the deformation along the boundary between the Vermilion Granitic Complex (VGC) and the Vermilion district indicates that the two terranes have seen a similar deformation history since the earliest stages of folding in the area.
