摘　　要：提出了基于单相关系数搜索的变形的n维黄金分割算法,根据重磁异常反演了济阳坳陷花沟地区的视密度与视磁化强度的空间分布。结合钻井、磁力和重力异常图圈定了其火成岩的分布:推断出42个酸性火成岩体和33个基性火成岩体;按200m的深度间隔分11层编制的800-3000m内各深度层上的火成岩分布图,较好地展示了火成岩的空间位置。An n dimensional golden section algorithm based on variational single-correlation coefficient search is presented. Based on the gravity and magnetic anomaly, the spatial distribution of apparent density and magnetization in Huagou area of Jiyang depression was inversed. According to the drilling, magnetic and gravity anomaly information, the spatial distribution of igneous rock was deduced, which are 42 acidic igneous rocks and 33 basic rocks. The spatial distribution of igneous rock was well defined shown in maps from 800-3000 m in depth with 200 m interval.
