Quantitative petrographic investigations of porphyritic rhyolitic laccoliths of the Halle Volcanic Complex, Germany

Quantitative petrographic investigations of porphyritic rhyolitic laccoliths of the Halle Volcanic Complex, Germany

Felsic phenocrysts of the laccoliths have straight size distributions (characteristic lengths 3.4 to 36 mm) and R-values from 1.34 to 0.78 (randomly distributed, no touching frameworks). Laccoliths have crystallinities from 10 to 30%. Textural coarsening possibly played a role in crystallization his...
