摘要:Abstract(#br)Analyses of X-ray microfluorescence (XRF) elemental maps of the ichnofossil assemblages from the upper Pliensbachian-lower Toarcian marl-limestone rhythmite of the South Iberian Palaeomargin (Betic Cordillera, SE Spain) show that the compositions of burrow infills ar...

摘要:Abstract(#br)Extensive burning of Arctic tundra landscapes in recent years has contradicted the conventional view that fire is a rare, spatially limited disturbance in tundra. These fires have been identified as harbingers of climate change, despite our limited understanding...

摘要:Abstract(#br)Riverine Plain palaeochannels record periods of fluvial activity for Late Pleistocene southeastern Australia. In an attempt to develop a more detailed palaeoenvironmental record for this semi-arid region, we investigate the fine overbank sediments of the palaeoc...

摘要:Abstract(#br)Wetland sediments archive information about past terrestrial ecosystem change including variations in fire occurrence and terrestrial carbon fluxes. The charcoal content of sediments is important for understanding past fire regimes, as well as the role this reca...

摘要:Abstract(#br)The global climate cyclicity transferred from an Early Pleistocene mode dominated by the obliquity periodicity to a new Middle Pleistocene state dominated by the eccentricity periodicity in the absence of any significant changes in orbital forcing, known as the ...

摘要:Abstract(#br)The paleoceanic redox conditions and the vertical and spatial distribution of organic-matter-rich lower Cambrian Niutitang shales are varied in the Upper Yangtze region, China. An integrated approach, including organic geochemistry, major and trace elemental geo...

摘要:Abstract(#br)Studying the evolution of sea-level fluctuations, climate oscillations and tectonic movements in the Yangtze River Delta requires a reliable chronology. Here, we present the results of a comprehensive study of the magnetostratigraphy and cyclostratigraphy of a 295-m-...

摘要:Abstract(#br)Palaeogeographic changes that occurred during the Middle Triassic in the westernmost Tethyan domain were governed by a westward marine transgression of the Tethys Ocean. The transgression flooded wide areas of the eastern part of Iberia, forming new epicontinent...

摘要:Abstract(#br)The Ediacaran-Cambrian transition was characterized by the evolution from Ediacaran soft-body to Cambrian skeletal organisms, and fluctuations of the marine carbon cycle. Marine redox changes should have played an essential role in both ecological and environmen...
