Tertiary andesitic basalts of the Sirjan area, Urmieh-Dokhtar Magmatic Arc, Iran, contain plagioclase phenocrysts enclosed in a matrix of amphibole, clinopyroxene and rare olivine crystals. Textural and compositional evidence suggests two significantly different types of plagioclase phenocrysts occur in the andesitic basalts. The most common type of plagioclase phenocrysts have zoning patterns ...

We welcome Zhang et al.’s comment on our recent paper dealing with the significance of the first geochemical and geochronological analyses of deep drill-core samples collected from the basement of the central Tarim basin (Guo et al., 2005). In their comments, Zhang et al. raised three questions with regard to our paper (1) the compatibility of our model with regional geology, (2) our interpreta...

This article provides a background for scientists interested in a general overview of the geology and geomorphology of Turkmenistan. The basement of Turkmenistan is a complex amalgamation of arc-related terranes developed in the Asiatic and northern Paleotethys oceanic domains during Late Paleozoic to Triassic times. A major part of the country coincides with the Turan Platform, where a thick s...

The Avaj Oligocene volcanic – plutonic complex is part of extensive Cenozoic magmatic activity within the Urumieh-Dokhtar arc Iran. We use whole rock geochemistry, mineral compositions and crystal size distributions (CSD) in a suite co-genetic basalt, basaltic andesite gabbro to determine their petrogenesis. Ca-rich cores plagioclase (An79-86) overlap empirically modelled compositions, indicati...

Back-arc extension has been well documented in subduction plate tectonic regimes. However, the reasons why back-arc extensions are associated with some systems but not others have remained elusive. Here, spatio-temporal variations composition of Cenozoic basalts northeast Asian continental margin used to constrain mechanism for episodic extensions. Using geochemical data sensitive affinity, we ...

The Cordillera Real granitoids are a suite of Triassic and Oligocene plutons in the core Eastern Central Andes Bolivia. Their tectonic setting, chemical ore compositions make them part so-called “Inner Magmatic Arc”, which differs from current “Magmatic Arc” located immediately to west. U-Pb SHRIMP data were obtained order constrain crystallization ages. group yielded following results: 239±2 M...
