This paper is dedicated to the geochemical studies of two bottom sediment cores that were taken during cruise 28 of the R/V Professor Logachev in the Mid-Atlantic Ridge (MAR) 16°38'N area in 2006. The chemical compositions of background metalliferous and ore (ore-bearing) carbonate sediments are presented and inter-element correlations are examined. Individual episodes are distinguished in the accumulation history of the ore-bearing and metalliferous sediments on the basis of element factor analysis.

For more data on cruise PL28 see Rusakov et al. (2011) datasets: doi:10.1594/PANGAEA.790950. Note that data for cores PL28l-50 and PL28l-122 of Table 1 of Rusakov et al. (2012) and Table 2 of Rusakov et al. (2011) are largely overlapping but that some numbers are different.
