TheLa Macarena Fault (Spanish:Falla de La Macarena) is athrust fault in thedepartment ofMeta inColombia. The fault has a total length of 50.3 kilometres (31.3 mi) and runs along an average north to southstrike of 000.6 ± 9 along the east side of theSerranía de la Macarena.
The fault is named after theSerranía de la Macarena.[1]
The Macarena Fault extends along the eastern border of theSerranía de la Macarena, which is an isolated tectonic block to the east of theEastern Ranges of theColombianAndes. The fault thrustsPrecambrian crystalline rocks andTertiary oceanic rocks on the west over Tertiary andPleistocene continental rocks on the east. The course of theGuayabero River is controlled by the fault, showing strong lineations. Pleistocene sediments andalluvial terraces are apparently offset. There is a prominentfault scarp on the west side of the river.[1]
