Becoming Geologic

2017

Site-responsive performance, in which I stood on top of a calcareous tufa formation, while trying to receive on top of my head the water dripping that gives shape to this geological configuration. This macro-stalagmite grows by the aggregation of calcium carbonate —a mineral present in our bones— and other organic remains.

When runoff or rainwater penetrates into the soil, it is charged by carbon dioxide produced by bacterial and vegetal respiration; becoming acidic and therefore capable of dissolving calcareous rock. Acidic water transforms calcite into soluble bicarbonate, and can transport it through filtration across large bodies of rock. Upon re-emergence, waters degas the CO2 and the calcite precipitates to form rock once again.

Through the course of the entire performance, the water dripping from the cavity’s top marked my breathing rhythm and therefore, my respiration influx into the atmosphere; which added to water dissolves the rock, to mineralize once again on my hair and skin.
