A novel method for synthesizing homogeneous reference materials[08 26, 2014]

Reference materials play a crucial role for highly accurate isotope and trace element analysis of secondary ion mass spectrometry and they are used to calibrate instrumental fractionation of samples with various compositions. However, it is often ...

Block rotation: Tectonic response of the Sichuan basin to the southeastward growth of the Tibetan Plateau along t...[06 24, 2014]

It is widely accepted that the May 12 2008, Wenchuan earthquake was triggered by the oblique convergence between the Tibetan plateau and the Sichuan basin along the Longmen Shan fault belt. However, this interpretation is not supported by the fact...

  At several times in Earth’s history, mass extinctions have come close to wiping life out altogether. The reasons ...

Geomagnetic field variations from 8 kyr of Chinese history[06 05, 2014]

The geomagnetic field is generated by the motion of Earth’s fluid outer core and its variation is driven by internal dynamics, hence the behavior of geomagnetic field has significant implications for geodynamics. The geomagnetic field varies over...

Lithos + JAES : Permian to Triassic magmatism in the northern margin of the North China Craton[05 22, 2014]

The North China Craton (NCC) is distinguished from other global cratons by its intense decratonization during Phanerozoic. In recent years, it has become a key research field in the international Earth science community. Phanerozoic tectonics and ...

Oxygen escape linked to geomagnetic reversals and mass extinction[05 21, 2014]


  In the past half century, many efforts have been devoted to understanding the links between geomagnetic reversals and mass extinctions, but no consensus has been reached. The newest databases available for the Phanerozoic era illustrate that ...

Palynological evidence for the latest Oligocene-early Miocene paleo-altitude estimate in the Lunpola Basin, centr...[04 15, 2014]

The uplift of the Tibetan Plateau is the result of the collision of India and Eurasia and has been ongoing since at least the early Cenozoic. At present, many important questions about the tectonics of the Tibetan region are still debated: What me...

Abnormal lithium isotope composition from ancient lithospheric mantle[04 03, 2014]

Lithium has proven to be an important geochemical tracer for fluid-related processes in the Earth’s surface as well as crust-mantle recycling because of its moderate incompatibility during mantle melting, strong fluid mobility, and the large mass...
