If you enter an institutional mineralogical collection, you typically encounter glass cabinets organized by classification systems according to material properties. Yet, each mineral carries with it a history of extraction, destruction, (dis)possession, and global relations. Transpositional Geologies localizes such collections as indices of the afterlife of colonialism and proposes an evolving political geology, reading mineral specimens as objects of culture rather than of nature. Capturing his five-year artistic engagement and cultural collaboration in Namibia and Germany, Sascha Mikloweit brings together international voices from fields including anthropology, critical theory, geology, history, museum studies, philosophy, poetry, public administrationand the perspectives of boltwoodite, cerussite, or smithsonite. Rock by rock, this exquisitely designed volume invites us to engage with a progressively nuanced reading of geologys history: its epistemic violence, omissions, and racial regimes, and how the lasting residues of its colonial legacies continue to shape our present-day extractive realities.
