Conclusions a few fundamental relationships are typical to those margins:

  • Rifting task continues for a considerable time frame before breakup and subsequent seafloor spreading. When it comes to Nova Scotian margin this era had been because great as 40-50 Ma, for the Newfoundland margin 30-40 Ma as well as for Labrador 40-65 Ma. Pulses of volcanic task during rifting may happen, perhaps causing platform uplift as a consequence of localized underplating and/or thinning for the lithosphere, however these pulses appear to be localized as opposed to local in degree. Hence the margins are predominantly non-volcanic.
  • The spatial level of main rift task ultimately ultimately causing breakup from the margin that is southern laterally into the adjacent margin to your north. Hence the Triassic that is late to Jurassic rifting in the Scotian margin also impacted the Grand Banks while the belated Jurassic to Early Cretaceous rifting in the Grand Banks additionally impacted the Labrador margin.
