Abstract Rapakivi-type quartz monzonite and the underlying dark-grey granodiorite from Pietkowo IG1 borehole, in Polish part of southernmost Fennoscandia have been investigated using whole-rock geochemistry, Sm–Nd isotope geochemistry U–Pb zircon dating. The was emplaced at 1495–1491 Ma, although slightly older cores (antecrysts) 1513 Ma imply a two-stage crystallization. geochemical similariti...

The Wunugetushan large porphyry Cu–Mo deposit in NE China is hosted by Mesozoic quartz monzonite and has a Mo-rich core Cu-rich rim space. In this paper, melt inclusions intrusions fluid different-stage veins were studied to explore potential parameters leading decoupling. Melt have rhyolitic compositions of 71.7–85.3 wt.% SiO 2 , 1.9–31.3 ppm Cu 1.7–2.6 Mo. Hydrothermal activity occurred over ...

The Vathi porphyry Cu-Au ± Mo mineralization is located in the Serbo-Macedonian metallogenic province of Western Tethyan Metallogenic Belt. It mainly hosted by a latite and genetically associated with quartz monzonite intrusion, which intruded basement rocks Vertiskos Unit latite, 18 to 17 Ma ago. A phreatic breccia crosscuts latite. was affected potassic alteration, whereas subjected local pro...

This study provides a global assessment of the abundance major oxides in deep continental crust. The combination geochemistry and seismology better constrains composition middle lower crust than either discipline can achieve alone. inaccessible nature (typically >15 km) forces reliance on analog samples modeling results to interpret its bulk composition, evolution, physical properties. A common...

The bacteria colonizing geologic core sections (attached) were contrasted with those found suspended in the groundwater (unattached) by examining the microbiology of 16 depth-paired core and groundwater samples using a suite of culture-independent and culture-dependent analyses. One hundred twenty-two meters was continuously cored from a buried chalcopyrite ore hosted in a biotite-quartz-monzon...

hired is a large gold prospecting area which is located in south khorasan province, in the east of iran. gold mineralization is found in 4 target areas covering about 24 km2. the host rocks are mainly tertiary volcanics, some jurassic and cretaceous sediments. sub-volcanic rocks are of magnetite series (gabbros to diorite) and ilmenite series (granite-granodiorite-monzonite) which have intruded...

sorkheh-dizaj apatite-iron oxide deposit is located 32 km southeast of zanjan. the area is situated within the tarom subzone of western alborz-azarbaijan structural zone. the oldest units at the sorkheh-dizaj area are eocene trachyte, trachyandesite, olivine basalt and volcanoclastic brecciate tuff and lapilli tuff which intruded by a quartz-monzonite, monzonite and granite subvolcanic pluton o...
