We present a case study of applying 3D inversion gravity gradiometry data to iron ore exploration in Minas Gerais, Brazil. The bodies have distinctly high-density contrast and produce well-defined anomalies airborne data. carried out apply [Formula: see text] subarea from larger survey demonstrate the utility such associated algorithm characterizing deposit. examine multiple density models obtained by first inverting text]; then text], jointly; finally all five independent components understand information content different components. commonly discussed component is sufficient geologically reasonable interpretable results, while including additional involving horizontal derivatives increases resolution recovered model improves delineation. show that can be used delineate formation within this area.
