Oxidised rapakivi magmatism and crustal architecture in the earliest AMCG suite: geochemical and geophysical insights from Estonian intrusions along the Paldiski-Pskov shear zone (PPDZ), Wiborg-suite Complex, Fennoscandia

Abstract

This study combines geochemical, structural, and geophysical data to constrain the geometry, tectonic controls, and petrogenetic evolution of Estonian rapakivi intrusions within the first Wiborg Suite.
