Sea level changes recorded in mixed siliciclastic-carbonate shallow-water deposits: The Cala di Labra Formation (Burdigalian, Corsica)

•Wedge fed by nearshore siliciclastic supply and carbonate production basinward•The stratigraphic architecture records two depositional sequences (Bur3-Bur4).•Terrigenous input enhances capacity of carbonate factory to fill accommodation space.

A mixed carbonate-siliciclastic succession developed on the southern margin of the Bonifacio Basin (Cala di Labra, SE Corsica) during the Burdigalian, in the margin of a back-arc setting which had formed during the Sardinia-Corsica block rotation. This shallow marine setting was fed by abundant nearshore siliciclastic supply, and substantial carbonate production/accumulation increased from the euphotic to the oligophotic zones. Two third-order depositional sequences (SD1, SD2) corresponding to Bur 3 and Bur4, are recorded in the sedimentary succession.
