Methodology of Gravimetric Survey and Data Visualization. Gravity measurements detect variations in mass density; denser stone pulls more strongly. 1986 French team (Jacques Montron & Pierre Del) collected the data; later re‑analysis used 34 prism sections. Wallace corrected earlier diagram errors and produced a 3‑D density model with a green‑to‑red gradient.
