Diamantina Fracture Zone Diamantina Fracture Zone The Diamantina Fracture Zone is an area of the south-eastern Indian Ocean seafloor. It has a range of ridges and trenches. It lies to the south of the mideastern Indian Ocean features of the Wharton Basin and Perth Basin, and to the south west of the Naturaliste Plateau. Being parallel to the Southeast Indian Ridge, Diamantina Fracture Zone is not a real fracture zone in the sense of plate tectonics, but rather an escarpment, separating two oceanic plateaus. In fact its extension to the west is called Diamantina Escarpment. This is the southern border of the Broken
Tintina Trench Tintina Trench The Tintina Trench is a large valley extending through Yukon, Canada. It is the northern extension of the Northern Rocky Mountain Trench in British Columbia and it has its origin from the Tintina Fault. The northern part of the valley is occupied by the Pelly River, a tributary of the Yukon River. The southern Tintina Trench is drained by the Liard River which first flows south-eastward, then eastward and finally merges into the Mackenzie River at Fort Simpson, NWT where the combined waters turn back north for the Mackenzie's long flow to the Arctic Ocean.
