The snowball Earth hypothesis: testing the limits of global changeThe gradual discovery that late Neoproterozoic ice sheets extended to sea level near the equator poses a palaeoenvironmental conundrum. Was the Earth's orbital obliquity > 60° (making the tropics colder than the poles) for 4.0 billion years following the lunar‐forming impact, or did climate cool globally for some reason to the point at which runaway ice‐albedo feedback created a `snowba... ... hiện toàn bộ

The Variscan collage and orogeny (480–290 Ma) and the tectonic definition of the Armorica microplate: a reviewThe Variscan belt of western Europe is part of a large Palaeozoic mountain system, 1000 km broad and 8000 km long, which extended from the Caucasus to the Appalachian and Ouachita mountains of northern America at the end of the Carboniferous. This system, built between 480 and 250 Ma, resulted from the diachronic collision of two continents: Laurentia–Baltica to the NW and Gondwana to the ... ... hiện toàn bộ

The remarkable Re–Os chronometer in molybdenite: how and why it worksThe Re–Os (rhenium–osmium) chronometer applied to molybdenite (MoS2 ) is now demonstrated to be remarkably robust, surviving intense deformation and high‐grade thermal metamorphism. Successful dating of molybdenite is dependent on proper preparation of the mineral separate and analysis of a critical quantity of molybdenite, unique to each sample, such that recognized sp... ... hiện toàn bộ

Subduction and eduction of continental crust: major mechanisms during continent‐continent collision and orogenic extensional collapse, a model based on the south Norwegian CaledonidesABSTRACT During continental collision in the middle Silurian, the thickness of the lithosphere under the Caledonides of S. Norway was doubled by subduction of the western margin of Baltica, including the Western Gneiss Region, under Laurentia. Crustal rocks of the Baltic plate reached sub‐Moho depths of near 100 km or more as inferred from the presence of coesite in... ... hiện toàn bộ

Age refinement of the Messinian salinity crisis onset in the MediterraneanAbstract We propose a revised age calibration of the Messinian salinity crisis onset in the Mediterranean at 5.971 Ma based on the recognition of an extra gypsum cycle in the transitional interval of the Perales section (Sorbas basin, Spain) and the revision of the magnetostratigraphy of the Monticino section (Vena del Gesso basin, Italy). This age re‐calibration al... ... hiện toàn bộ

Neoproterozoic cap carbonates: a critical appraisal of existing models and the plumeworld hypothesisAbstract Evidence for glaciation during the mid‐late Neoproterozoic is widespread on Earth, reflecting three or more ice ages between 730 Ma and 580 Ma. Of these, the late Neoproterozoic Marinoan glaciation of approximately 635 Ma stands out because of its ubiquitous association with a characteristic, microcrystalline cap dolostone that dr... ... hiện toàn bộ

The Cimmerian Orogeny in northern Iran: tectono‐stratigraphic evidence from the forelandAbstract From the Permian onwards, the Gondwana‐derived Iran Plate drifted northward to collide with Eurasia in the Late Triassic, thereby closing the Palaeotethys. This Eo‐Cimmerian Orogeny formed the Cimmeride fold‐and‐thrust belt. The Upper Triassic–Middle Jurassic Shemshak Group of northern Iran is commonly regarded as the Cimmerian foreland molasse. However, ou... ... hiện toàn bộ

Are the oroclines of the Variscan belt related to late Variscan strike‐slip tectonics?Terra Nova, 23, 241–247, 2011 Abstract Early Variscan structures and magnetic anomalies delineate four oroclines along the Variscan belt. The arcs bend the lithostratigraphic zones of the autochthon and the allochthonous terranes, which include ophiolites of the Rheic suture and units of Gondwanan derivati...

The Valanginian carbon isotope event: a first episode of greenhouse climate conditions during the CretaceousABSTRACT Lower Cretaceous pelagic carbonates outcropping along the Southern Alps of northern Italy provide a record of Tethyan palaeoceanography as well as of low frequency fluctuations in the global carbon cycle. The carbonate C‐isotope stratigraphy established at five selected localities in the Southern Alps allows an accurate picture to be drawn of the duration a... ... hiện toàn bộ

Was Cathaysia part of Proterozoic Laurentia? – new data from Hainan Island, south ChinaAbstract We report here new field and analytical data from Precambrian rocks on Hainan Island of the Cathaysia Block, south China, and examine its probable connection to Laurentia. Granitoids and newly discovered felsic volcanic rocks dated at 1433 ± 6 Ma and 1439 ± 9 Ma (SHRIMP U‐Pb zircon) on Hainan Island are coeval with, and isotopically similar to the 1500–1350... ... hiện toàn bộ
