In this work INAA has been performed on some leached samples of Early Proterozoic gneissic biotite granite and augen gneiss from the Nei Monggol earth's axis for the contents of REE and some other trace elements. ...In this work INAA has been performed on some leached samples of Early Proterozoic gneissic biotite granite and augen gneiss from the Nei Monggol earth's axis for the contents of REE and some other trace elements. The results show that these two sorts of rocks and their leaching solutions and dregs have the same REE patterns.展开更多
Due to their similar chemical and geochemical properties, rare earth elements usually migrate as a whole and show regular variation in their relative abundance patterns in geochemical and cosmochemical processes.
