Chemical composition of iron-manganese and phosphate rocks from aseismic ridges of the Indian Ocean and from the continental slope of the Southeast Africa

Study of chemical composition of 26 samples collected at depths from 400 to 1400 m on vertex surfaces of the Southeast Indian Ridge, Mascarene Ridge, Madagascar Ridge, and Mozambique Ridge, as well as on the upper part of the Southeast Africa continental slope showed that the samples represent three groups of rocks: 1) low phosphate or phosphate-free ferromanganese rocks, 2) phosphate ferromanganese rocks 3) phosphorites and phosphatized limestones.

Women in movement : Gender relations in quilombola community Buriti do Meio on the North of Minas Gerais/Brazil

In a civilisation space of Sao Francisco basin river. Women and men interlace on their relations building mutual and each one on your way in handling of the clay in politics fights and in life daily of Buriti do Meio Quilombo. The objective of this study was to do a ethnographically reflection of gender relations that link men and women in the black rural community Buriti do Meio in Sao Francisco municipal district on the North of Minas Gerais/Brazil. We tried to understand the meanings and the composed representations on the feminineness and the masculine ways in relation that men and women set up among themselves in handling workmanship for the information in politics fight of community group as quilombo remaining and to rights access derived and everyday life where they build and organize together the life of all their members reflecting in his symbolic order. Buriti do Meio is traditional known for its handcraft and for cultural manifestations, legacy of their ancestral, olds slaves that ran way to look for autonomy and freedom express signs of afrobrazilian culture inserted on the civilization space in Sao Francisco basin river

Benthic foraminiferal fauna and isotope record in Holocene sediments of the northwest Indian Ocean

Historically, the Holocene has been considered an interval of relatively stable climate. However, recent studies from the northern Arabian Sea (Netherlands Indian Ocean Program 905) suggested high-amplitude climate shifts in the early and middle Holocene based on faunal and benthic isotopic proxy records. We examined benthic foraminiferal faunal and stable isotopic data from Ocean Drilling Program (ODP) Site 723 and total organic carbon data from ODP Site 724, Oman Margin (808 and 593 m water depths, respectively). At Site 723 the mid-Holocene shift in d18O values of infaunal benthic species Uvigerina peregrina (1.4 per mil) is 3 times larger than that of epifaunal benthic species Cibicides kullenbergi recorded at Site NIOP 905 off Somalia. However, none of the five other benthic species we measured at Hole 723A exhibits such a shift in d18O. We speculate that the late Holocene d18O decrease in U. peregrina represents species-specific changes in ecological habitat or food preference in response to changes in surface and deep ocean circulation. While the stable isotopic data do not appear to indicate a middle Holocene climatic shift, our total organic carbon and benthic faunal assemblage data do indicate that the early Holocene deep Arabian Sea was influenced by increased ventilation perhaps by North Atlantic Deep Water and/or Circumpolar Deep Water incursions into the Indian Ocean, leading to remineralization of organic matter and a relatively weak early Holocene oxygen minimum zone in the northwest Arabian Sea in spite of strong summer monsoon circulation.
