DM according to AI: Potassic alteration is a high-temperature hydrothermal process characterised by the addition of potassium, typically creating K-feldspar (often pink/orthoclase) and biotite. It often features quartz, magnetite, actinolite, and anhydrite, frequently hosting copper-gold mineralization in porphyry systems. It is identified by pervasive pinkish alteration in felsic rocks or biotite in mafic rocks.
