Abstract:	In qualitatively homogeneous magmatic bodies, quantitative texturalanalysissuch as crystal size distribution, modal abundance,and spatial distribution pattern analysesallows theirinternal heterogeneity to be measured and interpreted. In thisstudy, these methods are applied to samples from a 300 m drillcore through one of the porphyritic rhyolitic laccoliths (Petersbergunit) of the
