Sinistral to Normal Faulting along the Tan‐Lu Fault Zone: Evidence for Geodynamic Switching of the East China Continental Margin

摘要: Abstract The Tan‐Lu fault zone (TLFZ) along the East China continental margin (ECCM) experienced a change from sinistral to normal faulting in late Mesozoic. Thirty‐four laser ablation (LA)‐ICPMS zircon U‐Pb dates for plutons and volcanic rocks TLFZ indicate that extension‐related magmatism started as early 136 Ma. development of pre‐eruption rift basins during earliest Early Cretaceous further constrains onset time beginning (ca. 145 Ma). Association extensive rifts, metamorphic core complexes, with suggests an extensional regime ECCM also at Cretaceous, about An undeformed granite dike intrudes ductile shear yields LA‐ICPMS age 122 Seven 40Ar/39Ar plateau ages mica samples mylonites shear...
