摘要: New analyses suggest that animals colonized land sooner than previously thought, and maybe even before embryophytes (land plants). This has important implications for our understanding of the historical interactions ofterrestrial organisms with each other and their physical environments.关键词:...
The Rheic Ocean, which separated Laurussia from Gondwana following the closure of Iapetus, is arguably the most important ocean of the Palaeozoic. Its suture extends from Mexico to Turkey and its closure produced the climactic Variscan–Alleghanian–Ouachita orogeny that assembled the supercontinent, ...
Coastal estuaries, port basins and lagoons that have relatively moderate ocean currents and winds are more likely to accumulate pollutants. Offshore regions and undersea canyons can be used as conduits for transporting pollutants from the continent to the seabed. It is particularly noteworthy that the...
[1] Petrographic observations within oceanic gabbros drilled by Ocean Drilling Program (ODP) at Leg 153 from the Mid-Atlantic Ridge, Kane Fracture Zone (MARK) area (23°N) in combination with experimental findings suggest that the late stage magmatic evolution of these gabbros is characterized by...
The ocean floor started to subduct northward at ~125 Ma, causing backarc extension along the southern margin of the Eurasian Plate and the formation of the proto-SCS. The Neotethys subduction regime changed due to ridge subduction in the Late Cretaceous, resulting in fold-belts, uplifting, ...
The Changjiang (Yangtze) River, China, has formed a large tide-dominated delta on the western coast of the East China Sea. This paper presents the architecture and Holocene evolution of the delta, based on analyses of three borehole samples taken from the present delta plain. The deltaic sed...
Here, we relate trends in species richness and abundance from 21,500 terrestrial and marine assemblage time series across temperate regions (23.5–60.0° latitude) to changes in air or sea surface temperature. We find a strong coupling between biodiversity and temperature changes in the marine ...
their connection zones, namely the assembly among the Eurasian, Pacific and India-Australia plates and the related effect from the deep mantle, lithosphere, to crust and surface Earth system, and some related issues within the connection zones of the two oceans under the super-convergent back...
The Bangong-Nu Jiang mini-ocean opened within the northern Tibetan block probably in late Triassic-early Jurassic time and closed in the late Jurassic. The development of the Neo-Tethys spanned an interval from Permian to early Tertiary and obduction of ophiolites took place in Jurassic to ...
