The evolution of the atmosphere in the Archaean and early Proterozoic被引量：2
《Chinese Science Bulletin》2011年第1期4-13,共10页NISBET Euan FOWLER C Mary R 
Key steps in atmospheric evolution occurred in the Archaean.The Hadean atmosphere was created by the inorganic processes of volatile accretion from space and degassing from the interior,and then modified by chemical a...

Zircon isotopic ages from magnetite quartzites of the Jianping metamorphic complex, western Liaoning Province
《Chinese Science Bulletin》2000年第6期547-551,共5页A.Krner A.A.Nemchin 
Using the zircon Pb evaporation method and high precise ion microprobe analyses, zircon isotopic ages in supracrustal magnetite quartzites from Jianping metamorphic complex have been obtained. The results show that th...
