Шаблон:Short description Шаблон:Infobox fault The Cimitarra Fault (Шаблон:Lang-es) is a sinistral oblique thrust fault in the departments of Antioquia, Bolívar and Santander in central Colombia. The fault has a total length of Шаблон:Convert and runs along an average northeast to southwest strike of 323 ± 3 in the Middle Magdalena Valley and Central Ranges of the Colombian Andes.

Etymology

The fault is named after the Cimitarra River, Antioquia, a left tributary of the Magdalena River.[1]

Description

The Cimitarra Fault splays from the Palestina Fault in a northeasterly direction on the eastern border of the Central Ranges of the Colombian Andes,[1] passes north of Barrancabermeja,[2] and possibly connects to the Bucaramanga-Santa Marta Fault in the northeast.[3] The fault displaces Jurassic to Cretaceous volcanic rocks, Mesozoic igneous rocks, a Tertiary erosion surface in the Central Ranges, and late Quaternary sediments. Portions of the fault are pre-Pliocene in age, since it is locally covered by undeformed Pliocene sediments. Farther northeast, the fault is overlain by young alluvial deposits of the Middle Magdalena Valley.[1]

The fault is marked by well preserved fault scarps, long straight traces, displaced drainages, and it forms aligned river courses. The slip rate is calculated at Шаблон:Convert per year.[4]
