Containing or relating to both aluminum and iron compounds, particularly in chemistry, geology, or metallurgy.
From alumino- (combining form from aluminum) plus -ferric (from Latin ferrum, iron), coined in the 1800s to describe compounds or minerals containing both metals.
Aluminoferric minerals are incredibly common in Earth's crust—they often contain the iron that makes rocks magnetic and the aluminum that makes them weather at specific rates, directly shaping landscape formation.
