It has previously been thought that in Sind the Meting Limestone Laki Limestone succession was equivalent to the Bolan Limestone, and that argillaceous beds, which are occasionally developed above the Laki Limestone and below the overlying Khirthar, represented the Ghazij Shales. Recent evidence indicates that these higher argillaceous beds are the representatives of the Shales with Alabaster of the Western Punjab, that in Sind the Ghazij Shales are cut out at the Laki/Ranikot unconformity, and that the Meting Limestone-Laki Limestone succession represents calcareous horizons higher up in the Laki series than the Bolan Limestone.
