Abstract: This paper gives the interpretation on the characteristics of gravity anomalies implied by the tectonic block boundaries and their inner structures using the 2.5'×2.5' free air gravity anomalies derived with satellite altimeter data.The results show that the altimeter-derived gravity anomalies with high resolution are useful for investigating detailed structure of oceanic lithosphere and evaluating resource exploration.
