Deformation history of a Mesozoic forearc basin sequence on Alexander Island, Antarctic Peninsula
Read more of: Deformation history of a Mesozoic forearc basin sequence on Alexander Island, Antarctic PeninsulaThe Mesozoic Fossil Bluff Group of Alexander Island contains trench-slope and forearc basin deposits that formed during the eastward subduction of oceanic crust beneath the Antarctic Peninsula region. The oldest […]

Breakup and conditions for stability of the northern Larsen Ice Shelf, Antarctica
Read more of: Breakup and conditions for stability of the northern Larsen Ice Shelf, AntarcticaThe breakup of ice shelves has been widely regarded as an indicator of climate change, with observations around the Antarctic Peninsula having shown a pattern of gradual retreat, associated with […]

High latitude Eocene climate deterioration: evidence from the northern Antarctic Peninsula
Read more of: High latitude Eocene climate deterioration: evidence from the northern Antarctic PeninsulaClay mineral, sedimentological and geochemical data show that the northern Antarctic Peninsula (Seymour Island, La Meseta Formation) experienced a climatic deterioration from very warm, non-seasonally wet conditions at the end […]

Late Cretaceous–Cenozoic climatic variations of the northern Antarctic Peninsula: new geochemical evidence and review
Read more of: Late Cretaceous–Cenozoic climatic variations of the northern Antarctic Peninsula: new geochemical evidence and reviewAptian to Pliocene time-series of X-ray fluorescence data from the Antarctic Peninsula are used to assess the degree of chemical weathering and maturity of sediments deposited prior, and subsequent to […]

Antarctic Peninsular cryosphere: Early Oligocene (c. 30 Ma) initiation and a revised glacial chronology
Read more of: Antarctic Peninsular cryosphere: Early Oligocene (c. 30 Ma) initiation and a revised glacial chronologyStrontium isotope stratigraphy provides a chronology for Cenozoic cryogenic strata in the northern Antarctic Peninsula and allows an assessment of diachronism in onset of glacial conditions between East and West […]

Pétrologie et géochimie des basaltes de Murta : une éruption sous-glaciaire dans les Andes patagoniennes (46° lat. S.), Chili. Relation avec la subduction de la ride du Chili
Read more of: Pétrologie et géochimie des basaltes de Murta : une éruption sous-glaciaire dans les Andes patagoniennes (46° lat. S.), Chili. Relation avec la subduction de la ride du ChiliThe Holocene Murta basalts represent a small volume monogenetic centre located in the northern Patagonian Andes at the latitude of the Chile Triple Junction. These basalts show morphological evidence of […]

Note on the trophic relationships of the stauromedusa Haliclystus antarcticus from subantarctic South Georgia
Read more of: Note on the trophic relationships of the stauromedusa Haliclystus antarcticus from subantarctic South GeorgiaStauromedusae are cnidarians that have attracted relatively little ecological study, especially in the southern hemisphere. They are Scyphozoa that develop directly from the scyphistoma, and each consists of a calyx […]

Late Palaeozoic to Mesozoic structural evolution of the Falkland Islands: a displaced segment of the Cape Fold Belt
Read more of: Late Palaeozoic to Mesozoic structural evolution of the Falkland Islands: a displaced segment of the Cape Fold BeltThe Falkland Islands lie on a displaced crustal block presently forming part of the South American plate. The islands possess two roughly orthogonal structural grains, the relative chronology of which […]

Development of kinematic partitioning within a pure-shear dominated dextral transpression zone: the southern Ellsworth Mountains, Antarctica
Read more of: Development of kinematic partitioning within a pure-shear dominated dextral transpression zone: the southern Ellsworth Mountains, AntarcticaThe Heritage Range of the southern Ellsworth Mountains, West Antarctica, is composed of Cambrian to Permian sedimentary and volcanic rocks, which were deformed during the Permo-Triassic Gondwanian orogeny. The structural […]
