A closer look at “Deep-Sea Rocks Collected by ROV Spontaneously Combust in Lab”, exactly as the source publishes it. Marine scientists using the remotely operated vehicle Jason collected mineral samples from the Escanaba seafloor, only to have them unexpectedly catch fire in the laboratory. The incident, reported by ScienceAlert, highlights the volatile nature of certain deep-sea mineral deposits when brought to surface conditions. The rocks, rich in sulfides and other reactive compounds, can oxidize rapidly upon exposure to air, generating heat and flames.
This phenomenon underscores the challenges of studying and potentially mining seafloor massive sulfide deposits, which are of interest for their high concentrations of copper, zinc, gold, and silver. The Escanaba Trough, located off the coast of Northern California, is a site of active hydrothermal venting and mineral formation. Researchers from the Woods Hole Oceanographic Institution were involved in the collection, and the event serves as a cautionary tale for handling such materials.
