Intimate Xenolith is a soundscape and installation combining mythology, ritual, and geology to form a speculative ancestral narrative around healing, initially created as part of a 2021 pilot residency at Lapworth Museum of Geology. The work features a handmade bust, sculpted using skeleton leaves, wool, synthetic hair, mycelium packing and cowrie shells. To the right of the bust is its own shadow cast on the wall; the display box to its left, on loan from Lapworth Museum, contains the ultramafic igneous rock peridotite, and the mineral olivine. Peridotite is a geologically significant rock within the Earth's mantle, believed to be the source of material for the oceanic lithosphere, the outer layer of the Earth's surface. The accompanying soundscape, accessible via headphones, includes text written by Joyce Treasure and orated by the poet Red Medusa, as well as field recordings by Pauline A Bailey, Ola Brown, Rachel Brown & Aerona Moore. Intimate Xenolith explores the question: 'can we study the success of natural science, like a planetary oracle, to grasp how social science can proceed? Are there important resonances between the material and immaterial sciences?'.
