The age, petrogenesis and geodynamic implication of Xiaomiaogou granite porphyry dykes in the northern margin of the North China Craton were investigated using geochronology, geochemistry and Sr–Nd–Pb–Hf isotopic data. LA‐MC‐ICP‐MS zircon U–Pb dating yielded the concordant 206Pb/238U weighted mean age of 350.4 ± 1.4 Ma for the dykes, suggesting they were the productions of the Early Carboniferous...
Zircon LA-MC-ICP-MS U–Pb geochronology, major and trace element geochemistry, and Sr–Nd–Pb–Hf isotope analysis were performed on the Paleoproterozoic mafic dykes from the Wulashan area to investigate their petrogenesis and tectonic implications. The mafic dykes are diabase porphyries with a dominant mineral assemblage of plagioclase and clinopyroxene. Zircon U–Pb isotopic data yield weighted mean...
