  abstract = {{A} new aeolian dust record from the first 2200 m of the {EPICA}-{D}ome {C} ice core (75degrees06' {S}, 123degrees21' {E}) covering about 220,000 years of climatic history is compared to the {V}ostok (78degrees28' {S}, 106degrees48' {E}) ice core [{N}ature 399 (1999) 429]. {T}he two dust profiles are very similar and several common dust events allow to establish stratigraphical links. {T}he late {Q}uaternary period is characterized at both sites, and likely overall {E}ast {A}ntarctic plateau, by high dust input during glacial periods. {I}n the {EPICA}-{D}ome {C} ice core, the dust flux rises by a factor of similar to25, similar to20 and similar to12 in glacial stages 2, 4 and 6 with respect to interglacial periods ({H}olocene and stage 5.5). {T}he magnitude and pattern of changes are comparable in the {V}ostok, ice core. {I}n this study, the geographical origin of ice core dust ({ICD}) in cold periods has been investigated at both sites through {S}r-87/{S}r-86 versus {N}d-143/{N}d-144 isotopic tracers, following the previous studies of {G}rousset et al. [{E}arth {P}lanet. {S}ci. {L}ett. 111 (1992) 175] and {B}asile et al. [{E}arth {P}lanet. {S}ci. {L}ett. 146 (1997) 573]. {T}he new data and the existing ones allow to define the isotopic fields for dust at the two {A}ntarctic sites that are almost identical and restricted into the 0.708<{S}r-17/{S}r-16<0.711 and -5<ε({N}d)(0)<+5 ranges. {T}his suggests a common geographical provenance for dust at {V}ostok and {D}ome {C} and for all the glacial periods of the late {P}leistocene. {T}o decipher the {ICD} provenance, more than 50 samples of loess and aeolian deposits, sands and fluvioglacial sediments from the {P}otential {S}ource {A}reas ({PSA}s) of the {S}outhern {H}emisphere have been collected. {H}owever, the methodology has been refined with respect to former studies. {F}irst, the isotopic fractionation that can occur in function of grain size has been taken into account, and the {PSA}'s signature has been defined in the <5 μm size range, within which fine-grained dust reaching {A}ntarctica is found. {M}oreover, a possible contribution from carbonates on the samples from {PSA}s has also been also considered. {S}outh {A}frica and {A}ustralia can be excluded as dominant sources, but a partial overlap arises among southern {S}outh {A}merica, {N}ew {Z}ealand and the {A}ntarctic {D}ry {V}alleys isotopic fields, these latter two documented for the first time. {A} possible contribution from all these three sources cannot be excluded, but complementary arguments suggest the dominant contribution to {E}ast {A}ntarctic dust in glacial times deriving from the southern {S}outh {A}merican region of {P}atagonia and the {P}ampas. {T}his study shows a first-order uniformity in the dust flux and geographical provenance to the {E}ast {A}ntarctica plateau during glacial periods.
