Geochemical Study of the Osumi Granodiorite, Southwestern Japan

open access: yes
The Osumi Granodiorite, located on the Osumi Peninsula in southwest Japan, is an example of outer zone granites that were formed during a limited period (13–15 Ma) in response to the subduction of the Philippine Sea Plate.

Gold occurrences in the Kolmozero-Voronya Archean greenstone belt, Kola region: Geological, mineralogical, geochronological and isotope-geochemical characteristics

open access: yesЛитосфера, 2015
A multidisciplinary study of the Oleninskoe and Nyalm-1 gold occurrences located in the Kolmozero-Voronya greenstone belt (Kola region) has been carried out. These gold occurrences are interpreted as orogenic and connected with a complex of gabbrodiorite-

Zircon U-Pb geochronology and emplacement history of intrusive rocks in the Ardestan section, central Iran

open access: yesGeologica Acta, 2017
The Urumieh-Dokhtar Magmatic Arc (UDMA) is part of the Alpine–Himalayan orogenic belt and interpreted to be a subduction-related Andean-type magmatic arc. Along this belt, Eocene volcanics and some gabbroic to granitic bodies crop out.

On the Hitokabe granodioritic mass, Kitakami mountainland

open access: yesThe Journal of the Japanese Association of Mineralogists, Petrologists and Economic Geologists, 1969
The Hitokabe granodioritic mass intruded into Paleozoic sediments and ultrabasic rocks in the Kitakami mountainland is studied petrochemically. The results of the modal analyses show that this mass is mainly composed of the granodiorite and subordinately quartz diorite, and inner facies of the mass are more basic than the outer facies.

Geochemistry and K-Ar dates of the Mazagan granodiorite at V30-225, VA79-96KD and DSDP Hole 79-544A, off Moroccan coast

open access: yes, 1984
Gneissic granodiorite was recovered by drilling at the base of the Mazagan escarpment, 100 km west of the Casablanca, Morocco, at 4000 m water depth. Coarse, predeformative muscovite yielded dates of -515 Ma, fine-grained muscovite of -455 Ma, biotite ...

Modification of a magmatic tonalite to produce a megacrystal granodiorite by K-metasomatism, Monterey peninsula and northern Santa Lucia Mountains, California, USA [PDF]

open access: yes, 2001
A megacrystal granodiorite, occurring in a pluton in the Monterey peninsula of California, is gradational south to quartz monzonite and then to tonalite and trondhjemite and southeast to granodiorite and then to tonalite.
