Creighton fault

Creighton fault is a major fault line through the Sudbury Basin. It has a mapped length of 56 km, a throw of over 600m, and a shear zone 30m wide, and travels east–west through Lake Ramsey and the Creighton mine. The fault is the raison-d'etre of Greater Sudbury, and plays host to countless magmatic massive sulphide orebodies.
