This thin volume is one manifestation of a multi-year and multi-tentacled endeavor undertaken by the University of Minnesota’s School of Architecture and participants in the international, collaborative art-research project, World of Matter (2011–present). In particular, this volume builds from a symposium that took place in conjunction with the opening of the exhibition, “World of Matter: Mobilizing Materialities,” at the Katherine E. Nash Gallery in September of 2017. The four essays brought together here focus on territorial transformations in specific contexts—from the coast of Argentina and the oil fields of Saudi Arabia and North Dakota’s Bakken to the Earth’s oceanic depths and icy poles—all sites of extreme extraction. The authors explore various “geosocial formations,” to borrow a term from the geographers Kathryn Yusoff and Nigel Clark, demonstrating how earthly materials not only are mobilized by humans but also introduce frictions or even downright recalcitrance at times.
