The importance of clustering phenomena in magmas


  • Giuseppe Lucido


Currently, clustering phenomena receive considerable attention in stellar systems and in fluid-dynamics problems. Although the whirling motions are regarded as a problem of basic significance for geology, the mechanisms for forming clustering processes in magmas are still poorly understood. Luckily, the discovery of felsic clusters in some basaltic rocks of Western Sicily throws light on this subject. The main aspects of cluster evolution occurring in the magma are described, and a three-stage process is proposed. The coalescing mechanism and the interparticle interactions due to the surface forces are emphasized. In the author’s opinion the conditions now existing in the Earth’s upper mantle favour clustering phenomena of this kind.
