True granite (according to modern petrologic convention) contains both plagioclase and alkali feldspars. When a granitoid is devoid or nearly devoid of plagioclase, the rock is referred to as alkali feldspar granite. When a granitoid contains less than 10% orthoclase, it is called tonalite; pyroxe...
Initial isotope ratio data from the granitoid country rock are similar to those found in the metapelites. The initial ratios indicate predominantly recycled, aged granitic crustal materials for the sources of all of the samples. Five zircon samples, 4 from pyrope megacrysts and 1 from fine-...
Granitic Rocks (Cretaceous and Jurassic) Mostly tonality and quartz diorite, but including lesser amounts of other granitoid rocks. Potassium-argon ages determined on hornblende indicates plutons range in age from 143 to 166 Ma (Hotz, 1971) I have, over many years, scoured my land and confirm...
I selected a thin section of a granitoid rock to do some initial investigation. I analysed it using a FEG-SEM combined with a Wave WDS spectrometer and an Ultim Max 170 mm2EDS detector. I used an accelerating voltage of 20 kV and a beam current of ~20 nA. The mineral I...
Emplacement of the Long Reach segment prior to Late Devonian time is suggested by an unconformity between granitoid rocks of the Lingley suite and the Devono-Carboniferous Sagwa conglomerate. Contrasting geology in the Pocologan River and Long Reach areas: implications for the New River belt and co...
Geochronology and lithogeochemistry of granitoid rocks from the central part of the Central plutonic belt, New Brunswick, Canada: implications for Sn-W-Mo exploration [T.sub.7] : 5.0 ton [fed.sup.-1] compost +50 ppm Zn Micronutrient and compost induced changes of growth, yield, nutrient and...
Geochronology and lithogeochemistry of granitoid rocks from the central part of the Central plutonic belt, New Brunswick, Canada: implications for Sn-W-Mo exploration Accordingly, the GECF's partnership with other international energy organisations such as APEC, EUROSTAT, the IEA, OLADE, OPEC and ...
