Abstract The geological and geophysical data acquired during cruise 45 of R/V Akademik Nikolaj Strakhov regarding the structure of the Doldrums megatransform system in the Central Atlantic are presented. Taking into account the data of the previous expeditions, the structure of this region is examined in detail. The bathymetric data confirm the complex morphology, consisting of five dextral transform faults, separated by four active intra-transform rift segments and indicates the variability of tectonic conditions in this region. The dredged rocks are represented by the entire spectrum from the mantle to the upper crustal varieties and, together with the detailed topographic data, make it possible to identify the origin of the key structures in the Doldrums megatransform system.

低迷期（中大西洋）巨变系统结构的新数据

摘要 介绍了在 R/V Akademik Nikolaj Strakhov 45 号巡航期间获得的关于中大西洋 Doldrums 巨型变换系统结构的地质和地球物理数据。考虑到历次探险的数据，对该地区的结构进行了详细检查。测深数据证实了复杂的形态，由五个右旋转换断层组成，由四个活动的转换内裂谷段分隔，并表明该地区构造条件的可变性。疏浚岩石由从地幔到上地壳品种的整个光谱代表，再加上详细的地形数据，可以确定低潮巨变系统中关键结构的起源。
