Marine high Mg calcite cements in Teredolites-bored fossil wood; evidence for cool paleoclimates in the Eocene La Meseta Formation, Seymour Island, Antarctica

Aims to describe petrography and geochemistry of calcite cements precipitated in species borings from the lower 180m of La Meseta Formation on island. Interprets data in terms of diagenetic history of wood substrates and paleoclimatic significance of the cement. Also, cement provides reliable indicator of cool ambient waters for La Meseta Formation in late early to early middle Eocene.
