Weird iron ore behavior in MC [java] : MinecraftHelp
Weird iron ore behavior in MC [java] Unsolved. I was mining for iron in survival mode when something weird happened: I hit an Iron ore block, it disappeared in a flash of Minecraft smoke, and invisible mob popped out and started attacking me. I could only see its shadow, and this happened to all the iron ore in the area... please help!

Chapter 8 PROPERTIES AND BEHAVIOUR OF IRON IN CLAY .
PROPERTIES AND BEHAVIOUR OF IRON IN CLAY MINERALS Because iron (Fe) is the fourthmost abundant element in Earth's crust (6% of mass), next to oxygen, silicon, and aluminium, its ubiquitous presence in clays and clay minerals should be no surprise. It is, in fact, an intimate part of many processes occurring in natural ecosystems. Murad and Fischer [1988] reviewed the many pools of iron .
