Gravity measurements at the surface, in the shaft, and in the drifts of the United Salt Company’s mine at the Hockley salt dome have been analyzed to determine densities of sediments, cap rock, and salt rock. The curve derived from the gravity changes indicates the presence of lithologic breaks that correspond with the known geology of the shaft. The density values computed from this curve correspond closely with acceded values for near‐surface clastic sediments, limestone, gypsum rock, anhydrite rock, and salt rock.
