Detrital zircon age signatures of the Mesozoic in the Lusitanian Basin and implications for the evolution of Iberia–Newfoundland conjugate margins

Terra Nova, Volume 35, Issue 3, Page 203-212, June 2023., 2023
Abstract New detrital zircon age results from the Lusitanian Basin are integrated with published data for the Mesozoic of west Iberia and eastern Canada (4959 concordant ages). Zircons in new samples are either mainly Devonian‐Permian, Cryogenian‐Ediacaran or reveal a combination of these two age populations, showing secondary to minor Mesoproterozoic ...
