Igneous rocks in the South China Sea have broad prospects for oil and gas *** geophysical methods are important approaches to study the distribution of igneous rocks and to determine and identify igneous rock *** at the characteristics of gravity and magnetic fields in the South China Sea,several potential field processing methods are preferentially *** to the pole by variable inclinations in the area of low magnetic latitudes is used to perform reduction processing on magnetic *** preferential continuation method is used to separate gravity and magnetic anomalies and extract the gravity and magnetic anomaly information of igneous rocks in the shallow part of the South China *** 3D spatial equivalent distribution of igneous rocks in South China Sea is illustrated by the 3 D correlation imaging of magnetic *** the local anomaly boundaries are highlighted gravity and magnetic gradients,the distribution characters of different igneous rocks are roughly outlined by gravity and magnetic correlation analysis weighted by *** results show the distribution of igneous rocks is controlled and influenced by deep crustal structure and faulting.
