本文介绍了NIS “Akademik Ioffe” 第66航次地球物理场实验室工作人员所获得的材料及其预处理和解 释结果。文章中的材料根据其在航次中的研究程度分为两个部分。第一部分包括在主要剖面航渡过程中 顺带进行的测量(伴生测量)材料及其解释结果,具体包括亚速尔-直布罗陀断裂带区域和加那利海盆的 材料。第二部分则包含了在特定区块进行的、以最大可能测线密度完成的面积性测量材料。本部分包括对 以下区域的解释材料与结果:佛得角海脊、科特迪瓦海隆和罗克尔海山。 通过在NIS “Akademik Ioffe” 第66航次中获得的新数据,并辅以公开来源的材料进行补充,使作者能够 完成解释工作,获得了关于大洋地壳结构、形成与演化过程的新认识,并细化了大西洋研究区域的地质年 代学( Imarov G. S., 2025)。在对磁力测量材料进行初步解释后,作者对所研究的亚速尔-直布罗陀断裂 带区域磁异常的性质提出了假设。在加那利海盆,明确了M0线性磁异常的位置,以及蒂罗和亚特兰蒂斯 转换断层的位置。确定了罗克尔海山的火山成因,并提出了该海山下存在一个广阔蛇纹石化区域的假设。
