| Alteration processes: | The volcanic rocks exhibit regional propylitic alteration overprinted by silicification, and local potassium flooding or secondary growth on primary feldspars (Randolph and Ellis, 1989). Trace amonts of adularia has been identified as fracture coatings. No argillic alteration has been recognized. Some pyrite-filled fractures show narrow kaolinite-epidote-sericite alteration envelopes. Quartz veins may be accompanied by pyritization and silicification in the surrounding wall rock. |
