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.
