jebale barez plutonic complex is composed of granitoid intrusive bodyes and is located in the east - north east jiroft and  southeastern province of kerman on the lengths of the 57° 45' east to 58° 00' and northern latitudes  28° 30' to 29° 00'. plutonic complex composed of granodiorite, quartzdiorite, monzogranite and porphyritic granite. the microstructures observed in thi...

Chlorite flakes, as a product of alteration of biotite, the dominant ferromagnesian mineral in the Paleozoic granitic rocks of the Canadian Appalachians, have been analyzed by electron microprobe for major elements and by 57Fe M?ssbauer spectroscopy for the coordination and oxidation state of Fe. Comparison of M?ssbauer Fe3+/Fe ratios obtained from chlorite and its host biotite indicates that c...

s Diffusion of water in thermally fractured granite was studied by using pulsed field gradient NMR (PFGNMR) and MRI methods. Two different approaches gave consistent results, indicating that these methods can be applied for materials of low porosity with fracture networks.

The Vengen Granite, one of early Paleozoic granitic rocks crops out the southern end ridge, Kanino-tsume Peak at Main Shear Zone (MSZ) Sør Rondane Mountains, East Antarctica. This granite is composed medium- to fine-grained mylonitic biotite and cuts MSZ Zone. two-mica dykes locally intrude Granite. have foliations parallel Granite plagioclase, quartz, K-feldspar, biotite, muscovite with trace ...

Abstract in English The granite of Abeokuta is part the Older Granite suite basement complex southwestern Nigeria. Field observation has identified as porphyritic texture, with a preferred alignment megacrysts K-feldspar >5 cm that are mostly euhedral to subhedral shape. predominantly yellowish, but whitish and pinkish colouration also been observed. dark grey porphyritic, mafic rock composi...
