Design of organization and safety measures for the reclamation from friable asbestos of an industrial area in italy
No full textThe asbestos is a mineral with a fibrous structure in the group of natural hydrous silicates, present in the rocky form in many parts of the world with particular focus on countries such as Canada, Russia and South Africa. The only asbestos mines on the European continent are located in Italy and Greece. The term “asbestos” embraces a family of silicates which occur as flexible bundles of thin fibre units with nanometric diameter and micrometric to millimetric length
An Evolutionary Model for the Magmatic System of the Campi Flegrei Volcanic Field (Italy) Constrained by Petrochemical Data
No full textThe petrochemical characteristics of the Campi Flegrei juvenile products are here reviewed in order to give a comprehensive portrait of the main processes governing magma evolution. Particular emphasis is devoted to the definition of the shallow-level differentiation processes (fractional crystallization ± open-system assimilation/mixing/mingling/magma chamber refilling) which modify the composition of primitive magmas during their ascent to the surface. Constraints on the intensive parameters characterizing the Campi Flegrei magmas as retrieved from mineral geothermobarometry, melt inclusions studies, experimental petrology and phase equilibria modelling from the existing literature are also presented and critically evaluated. On such basis, a model for the Campi Flegrei magmatic system is proposed, in an attempt to construct a reference framework from which reasonable speculations of its possible future behaviour could be obtained
