Nano-scale size effect of biomimetic synthesized ferrimagnetic H-ferritin nanoparticles[04 27, 2015]

Research and applications of magnetic nanoparticles are very important in rock magnetism, environmental magnetism, biomedicine and nano-materials. Biogenic magnetic nanoparticles, in particular, are important due to their high crystallinity, unifo...

Shrinkage of the Earth’s magnetosphere due to decay of its dipole field[04 13, 2015]

The Earth’s magnetosphere is formed by the interaction of the solar wind with Earth’s dipole magnetic field. The boundary between the solar wind and Earth’s magnetic field is called the magnetopause. This boundary separates the magnetospheric p...

MAPS: Did life exist on Mars? NanoSIMS analysis of organic carbon from the Tissint Martian meteorite[12 09, 2014]

In addition to our home Planet, Earth, life was probably present on Mars. Evidence from the exploration of Mars, which includes topographic features and the presence of aqueous alteration minerals and sulfates, suggests the existence of liquid wat...

New electromagnetic method developed to identify deep ore bodies[12 04, 2014]

Huoqiu iron deposit is a representative Precambrian banded iron formation (BIF) deposit at the southern margin of the North China Craton (NCC). The BIFs are hosted in a mid- to high-grade Neo-Archean metamorphic formation and overlain by thick Qua...

Numerical modeling of the dynamical process of the North China Craton destruction[11 19, 2014]

From a geothermal point of view, areas of cratonic lithosphere are stable when surface heat flow is in equilibrium with the heat supply at the base of the lithosphere plus the heat generated by radioactive decay within the lithosphere. Archean cra...

Precambrian Research: the Central Tianshan Arc Terrane has late Archean to early Paleoproterozoic basement[10 22, 2014]

The Central Asian Orogenic Belt (CAOB) has drawn the attention of the international geoscience community over the past twenty years due to its distinct accretionary orogeny, prominent continental growth and large-scale metallogeny. A basic archite...

Paleomagnetic constraints on the Neogene tectonic rotation and timing of strike-slip faults in the southeast marg...[10 09, 2014]

Postdoc Shihu Li and his supervisors Rixiang Zhu and Chenglong Deng present a high-resolution magnetostratigraphy, rock magnetic and anisotropy of magnetic fabric study of the Dali Basin with the objective of constraining the timing of strike-slip...

Coseismic Ultrahigh-Pressure Metamorphism[09 16, 2014]

Eclogite breccias are formed by earthquakes in high-pressure metamorphic belts. Coesite is the high-pressure form of quartz. The coesite-bearing eclogite breccia found recently by Yang et al. from the Institute of Geology and Geophysics, CAS, at Y...
