Mutatá Fault

The fault is named after Mutatá.[1]

The Mutatá Fault is located in northwestern Colombia, between the Penderisco River and the Caribbean Sea. To the south, near the town of Mutatá, the Mutatá Fault approaches the Murrí Fault and the two fault zones practically merge. In this area, the Mutatá Fault places Cretaceous intrusive rocks and greenstones (to the east) in contact with sedimentary Tertiary rocks (to the west). Farther north, the fault cuts Tertiary and Quaternary deposits, with uplift of the eastern block. The Mutatá Fault is located near the junction of the Malpelo, Caribbean, and North Andean Plates. There is an elongate, tectonically depressed zone between the Mutatá and Murrí Faults. The Mutatá Fault has a prominent topographic expression near the town of Mutatá, as seen on SIR-A satellite images. To the north of Río Sucio, the Mutatá Fault shows discontinuous linear valleys, notches, and trenches (grabens). There are aligned hills and slope changes close to the Central Ranges. Fault scarps, sag ponds, and aligned valleys are very common tectonic features along most of the fault's trace.[1]

Some authors consider the fault the northern part of the Murrí-Mutatá Fault.[2][3]
