These transpression gave rise to the short magmatic quiescence in our study area. Keywords: tectonic evolution / the relationship between magmatism and mineralization / spatial-temporal framework / the Zijinshan ore-field / the Shanghang-Yunxiao mineralization belt 0. 引言 紫金山矿田位于...
as the earth's interior cooled and its crust and plate mantle became heavier, plate tectonics became a self-sustaining process which has never ceased and has shaped the face of our modern planet."
All other time points are accurate to the nearest whole number. The detection limits for H2 and H2O2 were 0.2 nmol g−1 and 9.2 nmol g−1, respectively. Full size imageOur data indicate that over timescales >1 h SiO• were reactive at 121 °C resulting in reduced H...

Our new U-Pb zircon date in Dalongtan (~50 km to the east of the ARSZ), combined with previously obtained high-precision dates of potassic rocks within and outside the ARSZ, further narrows down the time span of concentrated felsic magmatism to a duration ranging from 37.2 to 32.3 Ma ...
The primary pattern of the late Cenozoic to the present tectonic deformation of China is characterized by relative movements and interactions of tectonic blocks. Active tectonic blocks are geological units that have been separated from each other by active tectonic zones. Boundaries between blocks are ...
as well as updated paleo-elevation estimates are the main outputs of our surface processes simulations, calculated in each 0.1 Myr time increment (Fig.2). The direct comparison between model outputs and the palinspastically restored history of sediment accumulation from Macrostrat48(post-late Eocene)...
Plate tectonics is a scientific theory that explains the movement of the Earths surface and many of its most prominent geological features. It is responsible in forming the deepest trench in the ocean to the tallest mountain on land – and in the ocean as we’ll soon see. The uppermost laye...

The peopling of these islands within our timeframe was effected entirely by paddled vessels, with no evidence for use of the sail in the pre-contact Caribbean. Fig. 2 The Caribbean: toponyms mentioned in the text Full size image In this theater there is no Pleistocene precursor, in large ...
