The Barrovian zones are the metamorphic zones of metapelites in the order chlorite, biotite, garnet, staurolite, kyanite, sillimanite, each beginning at the isograd of its index mineral. The metamorphic field gradient of a region is the curve, in the pressure–temperature plane, through the peak conditions recorded by its rocks at the places where they now crop out.
