Going to start a little thread of these, that—having been reading Kathryn Yusoff a fair bit recently—I think of as #DiagramsOfDispossession.

They are all taken from geophysical surveys or mine planning documents of Global North mining companies prospecting for #TechnologyMetals in Sub-Saharan Africa.

Recent studio experiments visualising relationships between minerals and the #ElectromagneticSpectrum.

Samples collected from sites of geophysical prospecting for #TechnologyMetals and fragments of electronics are lit with prisms used to separate the visible spectrum into its consituent colours.

Doping prisms with specific metals enables them to transmit certain frequencies of light. The reflection spectra of raw ores can be used to target #CriticalMinerals.
