Resistant outcrops of Proterozoic volcanic exhalites indicate that the Cleator, AZ, region was once part of a volcanic arc setting. These outcrops are comprised of dark chert; nearby outcrops are comprised of banded iron formation and also are reported to include tourmalinite, a chemical sedimentary rock comprised of precipitated tourmaline.
