An international group of researchers involving geologists from Wits University (Prof. Rais Latypov and Dr. Sofya Chistyakova) in Johannesburg have come up with an unexpected conclusion that basaltic magma chambers can grow extremely rapidly—in months to years—making these chambers remarkable intrusive equivalents of caldera-forming eruptions associated with the Large Igneous Provinces. This research was published as a paper in Science Advances.
