Alunite - Wikipedia
Alunite occurs as a secondary mineral on iron sulfate ores. Alunite occurs as veins and replacement masses in trachyte, rhyolite, and similar potassium rich volcanic rocks. It is formed by the action of sulfuric acid bearing solutions on these rocks during the oxidation and leaching of metal sulfide deposits.

Alum - Wikipedia
The production of potassium alum from alunite is archaeologically attested on the island Lesbos. This site was abandoned in the 7th century but dates back at least to the 2nd century CE. Native alumen from the island of Melos appears to have been a mixture mainly of alunogen (Al 2 (SO 4) 3 ·17H 2 O) with potassium alum and other minor sulfates.

ALUNITE (Potassium Aluminum Sulfate Hydroxide)
Alunite is also known as alumstone and is a source of the stone known as alum, KAl(SO4)2 - 12H2O. Some alunite has also been used to recover potassium and aluminum. Alunite forms from the action of sulfuric acids upon potassium rich feldspars in a process called "alunitization". The sulfuric acids accompany hydrothermal solutions, usually rich in certain ore metals.
