Three Chinese ordinary chondrites,including Jilin (H5),Boxian (LL3.8) and Lujiang (LL6),have been studied for their Re and Os abundances and Os isotopic composition in whole-chondrite samples,separated magnetic and no...
10Be is mainly produced in meteorite by spallation reactions of cosmic ray particles with oxygen, magnesium, silicon or nitrogen in it. The threshold energy is above 500 MeV. The half lifetime of 10
In geochemistry and cosmochemistry, the data of element abundance in meteorites can provide information about the origin of solar system and the evolution of the earth. They reveal the physicochemical character of lun...
