Chemical composition, magnetic susceptibility and texture of sediments in a swamp from the Los Petenes Biosphere Reserve provide information about late Holocene hydrological variations on the western margin of the Yucatan Peninsula, Mexico. Periods of lower than average amounts of K‐bearing clastics during 2580–2050, 1100–825 and 700–160 cal a BP represent drought intervals. Magnetic minerals were...
Geochemical and magnetic characteristics of sediments from paleolake La Salada provide information about the last glacial hydrological conditions at the southern margin of sub‐tropical North America. Proxy records of runoff, lake water salinity, brine composition and provenance of organic matter are based on multi‐element concentration, magnetic susceptibility, mineralogy, carbonate content and C/N...
