Rare earth element (REEs) imprints and provenance of wetland sediments from Oaxaca coast, Mexico.

REEs in wetland sediments from the Oaxaca coast in southern Mexico were used to infer the sources and depositional processes by involving both the geochemical characteristics and geostatistical approaches. Statistically strong positive correlation between REEs confirmed similar origin in all the cores. Light REEs (LREEs) represented >84 % of ΣREE mean concentrations varies between 47.
