Article
The genesis of Eocene to Early Oligocene plutons and dykes emplaced in the suture zone between two colliding continental blocks in southeastern Iran has been the subject of debate concerning the processes that formed magmas and influenced their intrusive history. We report geological, geochemical, mineralogical and isotope evidence that constrains...

In the northeast of Iran, in Shandiz-Virani-Mashhad Complex (SVMC), there are some outcrops of high-Mg ultramafic volcanic rocks. Based on detailed field observations and geochemical data, the komatiitic nature of these rocks has been well proven. These rocks have a wide range of volcanic facies and accordingly are divided into three groups of diff...

Olivine is a major constituent of the Earth’s upper mantle and also is the main crystallization product of magnesium-rich magmas. As a consequence, it is of prime importance to be able to use olivine as a geochemical and/or petrological tracer of physico-chemical processes occurring during the generation or ascent of magmas. The texture of olivine...
