Major controls of some metals distribution in sediments off the Nile Delta, Egypt.
MetadataShow full item record
The sediment samples that are collected during R/V CHAIN 1975 cruise to the southeastern Mediterranean have been used to determine the major controls of metals’distribution. The sediment samples were analysed mineralogically, chemically and texturally. The parameters measured included carbonate minerals, total carbonate, organic carbon, iron, manganese, copper, zinc, chromium, lead, nickel, cobalt, vanadium, calcium, magnesium, strontium, sand, silt and clay. The statistical analysis of data showed that four major factors control the distribution of metals in sediments of the Nile cone; These are: Factor 1 terrigenous mud-calcareous sand; Factor 2 Aragonite mud-terrigenous sand; Factor 3 Algal sand; and Factor 4 Aragonite. The percentages of terrigenous sand, mud and calcareous components of the Nile cone sediments greatly affect the elements spatial distribution. In addition to that, minor controls such as precipitation and coprecipitation may affect the elemental distribution. The d.....
