1. Amygdaloid an effusive rock with large, slightly elongated pores filled with secondary deposits of various minerals (quartz, zeolites, chlorites, and calcite)

2. The copper sulphides (chalcocite, bornite with accessory chalcopyrite and pyrite) and associated minerals (chlorites, sericite, albite, epidote, quartz) crystallized during the cooling of the ignimbrite and were included in pyromeride textures.

3. Moreover, the process does not form any undesired by-products, particularly MX(Mutagen X), THM(Tri Halo Methanes), HAA(Halo Acetic Acids), Alkali metal sulfates, Chlorites, Chlorates, free Chlorine, Chloramines etc.
