Physical properties
Hardness varies between 5-7 depending on mineral content; exhibits distinctive wavy banded colors of gray, black, and white with a sub-to-vitreous luster and foliated crystal structure.
Formation & geological history
Formed through intense regional tectonic compression and high-temperature metamorphism of pre-existing sedimentary or igneous rocks over millions of years.
Uses & applications
Primarily studied in structural geology and academic research; occasionally used as crushed stone in aggregate construction.
Geological facts
This dramatic outcrop illustrates ductile deformation, where solid rock behaves like a plastic fluid under immense heat and directed pressure.
Field identification & locations
Easily identified in the field by prominent chevron or recumbent fold structures visible in roadcuts and mountain ranges worldwide.
