The pre-Atlantic Hf isotope evolution of the east Laurentian continental margin: Insights from zircon in basement rocks and glacial tillites from northern New Jersey and southeastern New York
Zircon U–Pb age and Hf data from the Laurentian margin Data is for glacial tillites and basement rocks in New York and New Jersey. Basement rocks include Late Ordovician aged magmas and Mesoproterozoic arc crust. Together, the data reveals crust building processes along the Laurentian margin.
