Geochemistry and Thermobarometry of Bazman volcanic rocks, An example of active continental margin volcano
Bazman volcano is located in the Makran-Chaghi magmatic arc in southeastern Iran. Many studies have been done on this volcano, especially of petrology such as: Biabangard and Mollazadehbarvati, 2017; Berberian and Berberian, 1982; Mohammadi, 2005; Sahandi et al., 2010; Schmidt and Dabiri, 2019; Firoozkoohi, et al., 2017; Ghodsi et al., 2006; Glamghash et al., 2015; Karimpour et al., 2012; St...

متن کاملPetrology of rocks in the Karik area, east of Meiduk mine of volcanic
Around The Karik village, east of Meiduk mine, Eocene volcanic rocks (andesitic basalt, andesite, dacite and rhyolite) and pyroclastic rocks (agglomerate and tuff) are exposed. These rocks are cut by several andesitic dikes. The major textures in the volcanic rocks are porphyritic and flow textures. The minerals such as plagioclase, alkali feldspar, quartz, pyroxene, amphibole, biotite and opaq...
متن کاملPetrology and source of Plio-Quaternary volcanic rocks in southwest of Nir, South of Yazd
In the southeast of Nir, south of Yazd Povince, several acidic volcanoes rocks are exposed and form the youngest volcanic rocks in this region with dacite-rhyodacite composition. These rocks are composed of plagioclase, hornblende, biotite and quartz phenocrysts with trachytic and hyallomicrolithic porphyry texture. Based on geochemical data, the magmatic affinity of these rocks is calc-alkali...
متن کاملPetrology and Geochemistry of Neogene Continental Basalts and Related Rocks in Northern Taiwan (iii): Alkali Basalts and Tholeiites from Shiting-yinko Area
Basaltic rocks exposed in the Shiting to Yinko area in northern Taiwan are considered to represent a member of the products of the Neogene intraplate volcanism in the Fujian-Taiwan region of the SE China continental margin. This paper presents new age dating, petrographic (including mineral chemistry) and geochemical data which suggest the existence of two groups of the basaltic rocks: the earl...
