Strike slip shear zone in Uruguay
Shear zones and terranes in Uruguay after Gaucher et al ., 2008.[1] Sarandí del Yí Shear Zone is marked as "SYSZ". To the east Sierra Ballena Shear Zone is marked as "SBSZ".
The Sarandí del Yí Shear Zone is a strike slip shear zone in Uruguay . The shear zone has a NNW-SSE orientation and a dextral relative direction. It runs across the Río de la Plata Craton from the coast east of Montevideo in the south to the town of Sarandí del Yí . Sarandí del Yí Shear Zone shows a relative displacement of 40 kilometres (25 mi) and truncates the Uruguayan dyke swarm to the west.[2]
