摘　　要：通过对琼北地区1∶20万重磁资料的分析,结合地质、钻探等资料,推断了隐伏或半隐伏断裂20条,圈定了12个新生代凹陷和2个凸起,基本搞清了本区的地质构造特征与性质,为今后该区地质构造研究、城市规划等提供了依据。Based on an analysis of 1 ： 200 000 gravity and magnetic data obtained from northern Hainan area in combination with geological and drilling data, the authors deduced 20 concealed or semi-concealed faults and delineated 12 Cenozoic depressions as well as 2 domes and basically found out characteristics and properties of geological structures in this area. These achievements are of great significance for further geological-structural studies, city planning and economic construction.
