The Sierra de Guasayán (Eastern Sierras Pampeanas, Argentina) is formed by low to medium grade metamorphic rocks intruded Cambrian metaluminous (La Soledad quartz-diorite), slightly peraluminous (Guasayán, El Escondido and Martirizado granodiorite plutons), strongly (Alto Bello granodiorite) granitoids of the Pampean magmatic arc. Chemical compositions amphibole, plagioclase, biotite, titanite ...

Khezr-Abad pluton is cropped out in North-West of Taft. This granitoid seems to be younger than the surrounding metamorphosed rocks, particularly the lower cretaceous limestones and probably is implaced during Oligo-Miocene. The most volumetric abundances of the igneous rocks are: granodiorite, granite, quartzmonzo-diorite, quartz-diorite, and in a lesser amount tonalite, quartz-syenite and ...

The Nedamo Belt in the Kitakami Massif, NE Japan, contains early Carboniferous and Early Triassic accretionary complexes. Tectonic blocks containing plutonic rocks, ultramafic rocks high-P/T schists occur these complexes characterize Belt. comprise hornblende gabbro quartz diorite, they have been identified at more than 50 localities. U-Pb dating of zircon from diorite using inductively coupled...

the arghash area is located 45 km to southwest of neyshabour. the subvolcanic rocks in the area consist of biotite hornblende quartz monzodiorite porphyry, hornblende biotite quartz monzodiorite porphyry, hornblende monzonite porphyry, biotite hornblende monzonite porphyry, monzodiorite porphyry and biotite quartz monzodiorite porphyry units. the volcanic rocks consist of hornblende biotite dac...

the halak abad prospect occurs in the northeastern part of central iran zone (sabzevar structural zone). in this investigation, geochemical evolution, age and source of part of northeastern iran magmatic arc (intrusive bodies) in halak abad area in the khorasan razavi province has been studied. the exposed rocks consist of volcanic rocks with andesite and dacite nature, limestone, plutonic rock...

Texada Island (Figure 2-5-1) is with.in Wrangellia. Calcalkaline plutonism of the Coast plutonic complex is superimposed on this terrane. The northern part of the island is made up mainly ct basaltic amygdaloidal flows and pillovr lavas of the ?exad1 Formation (Karmutsen Fbrmation) overlain by massibe grqi limestone and white marble of the Marble Bay Fonnatio I (Quatsino Formation). These Upper...
