A geological process where rocks are chemically altered to form grunerite, a type of iron silicate mineral, usually through exposure to heat and pressure deep underground.
From grunerite (named after German mineralogist C.A. Grunert) plus the suffix -ization meaning 'to make or become.' The process was named after the mineral that forms as a result of this transformation.
This word reveals how geologists name processes after the minerals they produce—gruneritization is what happens when iron-rich rocks get cooked in Earth's oven, creating the striped banded iron formations you can see in places like Minnesota's Iron Range.
