The north-south, right-lateral transform stress, generated by plate motions between
India and Antarctica, created second order motions between India and Sri Lanka,
leading to development of the Cauvery Basin depressions in a pull-apart manner. The
northeast-southwest trend may have been dictated by a pre-existing shear zone in the
Precambrian crustal block of southern India.
由于印度和南极洲板块的运动引起的N-S向、右旋方向转换应力引起的印度和斯里兰卡之间的次级运动导致了Cauvery盆地以张裂性质的沉降运动的产生和发展。在印度南部Precambrian地壳快中的NE-SE方向表明这里原来存在一个剪切带。
