Dating of Precambrian Metasedimentary Rocks and Timing of their Metamorphism in the Soursat Metamorphic Complex (NW IRAN): Using LA–ICP-MS, U–Pb Dating of Zircon and Monazite
Soursat Metamorphic Complex (SMC) in west of Takab city is one of the polyphase metamorphic terrenes in northern Sanandaj-Sirjan metamorphic belt of Iran. The SMC composed mainly of metasedimentary rocks associated with granitic intrusions. Based on metamorphic rocks, two metamorphic phases could be separate in the complex. M1 is representative of regional metamorphisms which varies from greens...
متن کاملMetal in Ureilites: Siderophile Elements from La-icp-ms
Introduction: Bulk ureilites have near chondritic abundances of siderophile elements [1-7], showing no correlation with Fe contents (~5-16 wt.%) or mg (molar Mg/[Mg+Fe]). These observations are difficult to reconcile with any igneous model for their silicates [8]. We address this problem through detailed characterization of the metal phases in ureilites [9], and petrologic modelling [10]. Here ...

متن کاملA distinct source and differentiation history for Kolumbo submarine volcano, Santorini volcanic field, Aegean arc
This study reports the first detailed geochemical characterization of Kolumbo submarine volcano in order to investigate the role of source heterogeneity in controlling geochemical variability within the Santorini volcanic field in the central Aegean arc. Kolumbo, situated 15 km to the northeast of Santorini, last erupted in 1650 AD and is thus closely associated with the Santorini volcanic syst...
