 As a result of a process of sedimentation and water percolating through the shelly sands, the mixture later lithified when the lime content dissolved to cement the grains together.Exposed limestone formations at The Pinnacles Desert near Cervantes clearly show the limestone formation through the sedimentary process.At its thickest, the Tamala Limestone comprises the massive Zuytdorp Cliffs, up to 250 m high, extending for 150 km between Kalbarri, Western Australia and south of Steep Point.
