Various chemical pretreatments have been developed to remove organic and inorganic contaminants and to clean the head capsules prior to isotope analysis, but so far there is no standardised routine method to assess the purity of the isolated chitin. We present a dataset of oxygen isotope analyses of head capsules from seven lakes in southern South America. The head capsules were assigned to three different taxonomic groups of Chironomidae (Chironominae, Orthocladiinae, Tanypodinae) and to Ceratopogonidae. Orthocladiinae exhibited on average higher isotopic fractionation relative to lake water than the other taxonomic groups, although these differences were not statistically significant. Elemental analyses demonstrate that the oxygen content and molar N/O ratio of the head capsules have a larger influence on oxygen isotopic composition than the host water isotopic composition suggesting a strong influence of incomplete deproteination on oxygen isotope values of chironomid head capsules. This is backed up by an experimental approach with differently pretreated chironomids, which exhibits a strong correlation with N/O ratio presumably due to various degrees of deproteination. According to the N/O ratio, pure chitin was obtained after removal of the minerogenic fraction with a mixture of 10 % HF and 5 % HCl (16 h, 20 °C) and subsequent treatment with 5 % NaOH (2 h) and 7 % NaClO₂ (10 h).

The oldest sequence of fan deposition (∼40 ka) appears eroded and disconnected from active channel deposition. Other regionally distributed fan sequences are dated to 14–11 ka, ∼8 ka, and 3–1 ka. Common depositional timing of the thick 14–11 ka fans in catchments sourced from high and intermediate elevations suggests a common factor in generating these fans, possibly linked to a regional precipitation increase derived from Pacific moisture sources in the context of a gradual temperature rise since the local last glacial maximum. A short duration fan sequence occurred centered at ∼8 ka in some outlets sourced from high-elevation catchments. The occurrence of the 8 ka fans during the most arid period of the Holocene in the subtropical Andes suggests an easterly moisture source for the precipitation events that generated the fans, that could be associated with an effect of the 8.2 ka event (Bond event 5) leaking into the Southern Hemisphere. A minor Late Holocene aggradation period is linked to a regional humid period with westerlies as the principal moisture source and an increase in ENSO-warm signal frequency and intensity as a driver. Fan aggradation occurs during periods with both ascent and descent of the major regional vegetation ecotones.

A structural equation model was applied to elucidate the mechanisms underlying vegetation change in the Ejina Oasis.
