- ‘They also noted that much kaolin is in or near decomposed porphyry bodies that overlie the largest ore shoots in the Leadville Dolomite.’
- ‘The Henry Mountains consist of multiple intrusions of quartz-monzonite porphyries (predominantly plagioclasehornblende rocks) that were emplaced from 29.2 to 20.0 million years ago into a thick sequence of Mesozoic sediments.’
- ‘The fault places massive fractured greenstones over relatively undeformed feldspar andesite porphyry.’
- ‘This rare work of porphyry, limestone, serpentine and onyx is unique north of the Alps.’
- ‘During this time, many of the district's steeply dipping, northeast-trending faults were intruded by narrow, granodiorite porphyry dikes.’
