Abstract


Metamorphic and igneous rocks of Terpnis' Serres in N. Greece have been studied. Nowadays these metamorphic rocks are used as raw materials in stone wool production, by Fibran industry, whilst the studied plutonic samples with lower content of iron oxide are proposed as alternative raw material for the production of new lightly colored stone wool, according to the market demands. Selected epidote amphibolites and quartz diorite samples were analyzed by ICP ΟES, AAS, XRD, Petrographic microscopy, and SEM. The epidote-amphibolites show some evidence of weathering leading to sericiticsaussuritizated plagioclase crystals and secondary smectite and chlorite nanocrystals. Phyllosilicates affect positively the grinding procedure and melting of the raw materials under industrial conditions of stone wool production, due to its lower hardness and melting point compared to that of the primary hornblende. The chemical and major mineralogical composition, the heterogeneous characteristics of textures as well as the frequent presence of phyllosilicates, due to the weathering of the plutonic studied samples, are expected to contribute to the easier grinding and melting of rocks under industrial conditions as well as to the production of a new light colored and competitive stone wool product
