The 200 km 2 Poe Mountain intrusion, part of the 1.43 Ga Laramie anorthosite complex in southeast Wyoming, USA, preserves an exceptional range of primary magmatic and secondary deformation-induced structures that document the sequence of events involved in the emplacement, crystallization, and high-temperature deformation of a Proterozoic anorthosite. The intrusion consists of a steeply dipping (40–90°) olivine leucogabbroic to anorthositic margin of layered cumulates (minimum stratigraphic… CONTINUE READING
