摘要: The role of diagenetic processes in influencing the behaviour metals (Fe, Mn, Cu, Ni, Zn), rare earth elements (REEs) and environmental magnetic parameters two sediment cores from a polluted creek environment (the Thane Creek, Mumbai) was investigated. age determined using 210Pb analysis. Silty clays were dominant sediments both cores. Mineralogy showed presence quartz, calcite plagioclase feldspar bulk sediments, while smectite abundant clay mineral finer fraction. mean ΣREE lower than post-Archaean average Australian shale (PAAS). PAAS-normalized REE patterns MREE HREE enrichment with strong positive Eu Y anomalies. source rocks hinterland played an important on composition. Magnetic mineralogy dominance magnetite. Both low concentration Al, Ti, Fe Mn coinciding high grain size at middle portions. early changes portion masked by significant abundance content head OC fine magnetite region. Metals (Cu, Zn; factor >1.5) enriched suggesting anthropogenic source.
