in southeastern Cape Breton Island, Nova Scotia.
The focus of this paper is to study overprinting contact metamorphism related to a small calc-alkaline intrusion in low to medium grade regional metamorphic rocks and to model the thermal effects of pluton
emplacement at depths of less than 12 km.
Using drilling and geophysical mapping, six stock-like rapakivi granite plutons
were discovered under the 150300 m thick late Neoproterozoic and Palaeozoic sedimentary cover in the continental part of Estonia, all belonging to the Wiborg Rapakivi Subprovince with ages around 1.
The mafic plutons
east of the East Zone Cu-Ni-PGE sulphide mineralization are part of the FLIC based upon magmatic layering that formed mafic-ultramafic rocks similar to the layered rocks, anomalous PGE abundances in sulphide-bearing anorthositic gabbro and rare earth distribution patterns that are identical to the layered mafic-ultramafic rocks.
In places the potassium granites from the Naissaare, Neeme, and Marjamaa plutons
contain also hornblende, whose character, together with their lower Si[O.
respectively, these plutons
are the youngest felsic units yet dated within the St.
des ruisseaux Landry et Dickie et le corrige plutonique de Charlo, du Silurien tardif, recouvrent une superficie totale d'environ 80 [km.
Au mineralization on the EVG property is reported to be generally associated with Eocene-aged plutons
including those of phonolite composition as at North Stock and South Stock and monzodioritic composition at Antelope Flats.
Geochemical and isotopic data from many plutons
also argue against significant assimilation of local wall rocks (e.
There are probably many more icy plutons
still waiting to found.
Strong surface molybdenum and tungsten mineralization occurs within Cambrian sediments which have been intruded by two separate Cretaceous granitic to quartz monzonite plutons
8 Ga) crust; sparse volcano-sedimentary sequences enclosed in coeval tonalite-trondhjemite plutonic suites; voluminous granodiorite, granite, and pyroxene-bearing plutons
