Deformation of the “Anorogenic” Wolf River Batholith, Wisconsin, USA: Understanding the Baraboo Orogeny Hinterland

The Mesoproterozoic (~1470 Ma) Wolf River batholith (WRB) is exposed over 6500 km2, encompassing 11 plutons that crosscut the Archean Marshfield and Proterozoic Penokean terranes. As the WRB is the classically defined anorogenic batholith, to test this hypothesis, seven igneous phases were analyzed using anisotropy of magnetic susceptibility (AMS), as a proxy for magmatic flow during intrusion, and the samples recorded a sub-horizontal emplacement in six different orientations. Paleopoles from six of eight igneous samples preserve a wide variety of sub-vertical orientations with two reversed and four normal polarities. The synorogenic Baldwin Conglomerate is the youngest rock (
