| contents | Detailed geological, geophysical and lithological investigations of a section in the South Atlantic Ridge between 20°S and 30°S were made during Cruise 7 of R/V Professor Shtokman in 1982. The ridge is dissected by faults running across and along its strike. The bottom of the rift valley is at depth 3600-3800 m, and summits of seamounts are at depths 1800-2200 m. Aphyric and slightly porphyritic olivine-plagioclase basalts occur extensively in the rift zone, while highly porphyritic plagioclase basalts occur in the southern part of the area. All basalts are of the shallow depth central type representing plagioclase depth facies (15-30 km). Sediments (mainly foraminiferal-coccolithic oozes) occur in some depression traps. |
