Data on multidisciplinary research in the Tajura Rift (Gulf of Aden) during Cruise 7 of R/V Akademik Mstislav Keldysh in winter 1983-1984

In the collective monograph results of geological and geophysical studies in the Tadjura Rift carried out by conventional outboard instruments and from deep/sea manned submersibles \"Pisces\" in winter 1983-1984 are reported. Main features of rift tectonics, geology, petrology, and geochemistry of basalts from the rift are under consideration. An emphasis is made on lithology, stratigraphy, and geochemistry of bottom sediments. Roles of terrigenous, edafogenic, biogenic, and hydrothermal components in formation of bottom sediments from the rift zone are shown.

本文报道了1983-1984年冬季，采用常规舷侧仪器与深海载人潜水器“双鱼座（Pisces）”对塔朱拉裂谷（Tadjura Rift）开展地质与地球物理研究的综合专著成果。研究探讨了该裂谷的构造、地质、岩石学及裂谷玄武岩的地球化学主要特征，重点关注了海底沉积物的岩性、地层学与地球化学特征，并阐明了陆源、壤源性、生物成因及热液组分在该裂谷带海底沉积物形成过程中的作用。
