The Malayer plutonic complex: field geology, petrography and geochemical interpretation

The geochemical signatures like discordant variation of major and trace elements among felsic-intermediate and basic rocks  and  mafic enclaves of Malayer region on binary variation plots, decreasing values of FeOt, TiO2, MgO, MnO and CaO accompanied with increasing of SiO2 content from basic to felsic rocks, and decreasing Ni, Cr and Co with increasing SiO2 are considered as indications of mag...

Interactive multimedia rocks for geology

This paper presents the Ruskin Rocks project which is developing a rock instrument, making use of interactive multimedia to augment the musical characteristics of stones. Several historical rock instruments, which inspired the building of this instrument – iRock – are discussed. Fundamental vibration theory is applied to understand the musical nature of the rocks, and empirical data presented t...

GEOLOGY OF THE PRE-TERTIARY ROCKS IN THE ROCK CREEK-GREENWOOD AREA (82312) By James

Petrography and geochemistry of magmatic rocks in north of Kalate Shab area (East of Sarbisheh), Eastern Iran

The study area is located about 105 kilometers east of Sarbisheh in Southern Khorasan and in the Sistan suture zone. The magmatic rocks of this area are exposed as intrusive and sub volcanice including diorite, quartz diorite, porphyry quartz diorite and porphyry diorite with Oligocene- Miocene age. These rocks have granular, porphyry with fine- grained matrix, ophitic, intergranular and glomer...
