Summary:Data from 767 gravity stations in Lesotho are presented in the form of contoured Bouger and isostatic gravity anomaly maps which incorporate surrounding South African data. Anomaly correlation analysis suggests a mean D of 2.75 g/cm3 for the Drakensberg basalt. Compositional and topographic variations in the Precambrian basement have a strong influence on the anomaly pattern. [R.A.H.]
