THE PARTITIONING OF TRACE ELEMENTS IN SEDIMENTS AND SEQUENTIAL METHODS OF ANALYSIS
An investigation is to be carried out into the partitioning of a series of elements in long deepsea cores. Deepsea sediments are specialised deposits and differ from other terrestrial sediments in a number of ways; in particular, much of their trace metal content is held in ironmanganese oxide phases. The partitioning of elements in deepsea sediments has been studied by various workers. The sequential schemes used have been of various complexities. These range from the relatively simple two stage technique used by Chester and MerssihaHanna (1970), to the more complicated schemes employed by Heath and Dymond (1977) and Forstner and Stoffers (1981). In order to select the best partitioning scheme for deepsea sediments a study was made of the various sequential leaching techniques described in the literature and an appropriate version selected. This report outlines the basic concepts behind the use of sequential leaching schemes, gives a general survey of the relevant literature and describes the scheme selected in detail. This scheme is already in use on the ISPRA Atlantic core material already supplied and results are now beginning to be obtained.
