Known as the Great Oxidation Event, this was not a sudden catastrophe but a planetary transformation lasting hundreds of millions of years. The oxygen produced by these ancient microbes reacted with iron dissolved in the oceans, creating the banded iron formations we see in rocks today. This process likely triggered a 'Snowball Earth' – a global glaciation – as oxygen removed methane, a potent greenhouse gas, from the atmosphere. While it caused a die-off of anaerobic life that couldn't adapt, i

Closer to mineralization, the rocks begin to “tell the story.” Around lead–zinc mineralized zones, clear geological changes become evident: ✔️ Quartz veining becomes more pronounced ✔️ Host rocks show strong silicification ✔️ Oxidation and iron staining intensify due to hydrothermal fluid activity These features are classic pathfinder indicators that help geologists trace fluid pathways and vector toward economic Pb–Zn mineralization. Recognizing them early is key to successful exploration. #Lea
