Sierra Ballena Shear Zone

Shear zones and terranes in Uruguay after Gaucher et al., 2008.^[1] Sierra Ballena Shear Zone is marked as "SBSZ". To the west Sarandí del Yí Shear Zone is marked as "SYSZ".

Sierra Ballena Shear Zone or SBSZ is a sinistral strike-slip shear zone running across the Uruguayan Shield in eastern Uruguay and the Brazilian state of Rio Grande do Sul.^[2]^[3] The system was last active in the Precambrian.^[2]
