Last interglacial (MIS 5e) sea-level proxies in southeastern South America

摘要: Abstract. Coastal southeast South America is one of the classic locations where there are robust, spatially extensive records past high sea level. Sea-level proxies interpreted as last interglacial (Marine Isotope Stage 5e, MIS 5e) exist along length Uruguayan and Argentinian coast with exceptional preservation especially in Patagonia. Many coastal deposits correlated to MIS 5e solely because they form next-highest terrace level above Holocene highstand; however, dating control exists for some landforms from amino acid racemization, U∕Th (on molluscs), electron spin resonance (ESR), optically stimulated luminescence (OSL), infrared (IRSL), radiocarbon (which provides minimum ages). As part World Atlas Last Interglacial Shorelines (WALIS) database, we have compiled a total 60 MIS 5 attributed, various degrees precision, MIS 5e. Of these, 48 sea-level indicators, 11 marine-limiting indicators (sea elevation indicator), 1 terrestrial limiting below indicator). Limitations on precision accuracy chronological controls measurements mean that most these considered be low quality.
