Havre 2012 pink pumice is evidence of a short- lived, deep-sea, magnetite nanolite-driven explosive eruption
ABSTRACT: The Havre 2012 deep-sea rhyolite eruption went unobserved and was initially recognised from a massive pumice raft at the sea surface. Havre pumices are predominantly white or grey, however pink pumice is common in the raft. In subaerial explosive eruptions,...
Accelerated mineral carbonation of coarse residue kimberlite material by inoculation with photosynthetic microbial mats
ABSTRACT: Microbiological weathering of coarse residue deposit (CRD) kimberlite produced by the Venetia Diamond Mine, Limpopo, South Africa enhanced mineral carbonation relative to untreated material. Cultures of photosynthetically enriched biolm produced maximal...
