Pedogenic, lithogenic – or anthropogenic origin of Cr, Ni and V in soils near a petrochemical facility in Southeast Mexico
Large Cr, V and Ni contents were found in soils near Cd. Pemex in Tabasco, Mexico. Their origin was hypothesized to be either anthropogenic, derived from emissions of a petrochemical facility, or lithogenic, from the volcanic ash deposited
close and far away from the facility within the same land unit. The results highlight that the studied elements are of lithogenic and pedogenic origin; they were enriched dominantly through residual accumulation by lateritization, probably of mesozoic
The spatial variation of metal ions in soils is found to be controlled by pH, organic matter and clay contents, but in neutral or slightly acidic soils a significant part of metal content is of lithogenic origin. - (JS)

Accumulation rates of biogenic and lithogenic components were studied in 39 turbidite-free, well-dated sediment cores from the northern Indian Ocean to define the proportions of fluvial and eolian input and to reconstruct Quaternary patterns
