Anisotropy of magnetic susceptibility (AMS) has been extensively used in the last two decades to determine the emplacement mechanism of volcanic dykes. Late Cretaceous diabase dyke swarms are well distributed in Shengsi Island, eastern China.AMS was performed in 8 diabase dykes with distinct strikes. According to the analysis of the imbrications of magnetic foliations with the dyke walls, the authors infer magma flow direction: 1）in Huangsha Village, the NNE- trending dyke is fed by horizontal or sub-horizontal flow from southwest to northeast, while the EW-trending dyke is laterally injected from west to east; and 2）at Liujingtan, the NW-trending dyke is laterally injected from southeast to northwest while the NE-trending dyke from southwest to northeast.
