Petrofabric investigation of the sulfide-rich basal zone of the Duluth Complex
… unclear. This study investigates whether dynamic magma flow, characterized by shearing that produces mineral alignments or fabrics—influenced sulfide mineralization by transporting immiscible sulfide droplets within a flowing, crystal-rich mush prior to deposition.We analyzed oriented drill core …

Timing and emplacement of the Philipsburg batholith, SW Montana, and a comparison of two magnetic fabric techniques
… (AMS) is used extensively to determine magma flow fabrics in both intrusive and extrusive igneous rocks. The anisotropy of anhysteretic remanent magnetization (AARM) allows determination of the anisotropy of ferro/ferrimagnetic minerals in igneous rocks, which have a strong control on …

Structure and Accretion at Mid-Ocean Ridges With High Magma Supply: Perspectives From Seafloor Escarpments and Iceland
… are uncertain about specific details of magmatic and tectonic processes beneath these divergent plate boundaries and how these processes may vary along the spreading axis. Investigations that combine geologic relationships and magnetic properties continue to yield fundamental tools for …
