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...
