In her new work, Andrea Nagl investigates transformation and energy processes across micro- and global scales: from the Brownian motion of individual clay particles to orogeny. This investigation materializes in an engagement with the silent actors of deep time: clay minerals. As phyllosilicates like Smectite or Illite, they undergo a perpetual, cyclical identity shift—at times the suffering object of current and pressure, at times the acting subject that, through flocculation and diagenesis, itself creates new geological realities. This intrinsic role reversal, from fleeting suspension to durable rock and back again, radically questions the linearity of geological history. The work follows these non-human actors on their journey, dissolving the presumed boundary between object and subject, between passive material and active former, within the Earth's ceaseless metamorphosis.
