Factors affecting alkali-reactivity of quartz-rich metamorphic rocks: Qualitative vs. quantitative microscopy

Popis výsledku v původním jazyce

Several types of quartz-rich metamorphic rocks (medium-grained quartzite, fine-grained paragneiss, and fine-grained calc-silicate rock) all from the Techobuz quarry (Moldanubian Zone, Bohemian Massif, Czech Republic) were investigated with the intentionto quantify their alkali-silica reaction (ASR) potential, as well as to identify the alkali-reactive mineral phases. Mineralogical-petrographic methods (polarizing microscopy combined with cathodoluminescence, scanning electron microscopy combined with energy dispersive spectrometer, and petrographic image analysis) were combined with experimentally-determined data, obtained by the accelerated mortar bar test (following ASTM C1260). From the mineral and microstructural data of selected quartz-rich metamorphic rocks, the following parameters were proven to correlate positively with ASR susceptibility: quartz content, area, perimeter, and equivalent diameter. No correlations were indicated with shape parameters (shape factor, aspect ratio
