摘要: The chemical leaching method is used for a systematic analysis of distribution characteristics acid–soluble and acid–insoluble REE other trace elements from the Luochuan loess deposits. study shows that phase in palaeosol stable component old aeolian dusts characteristic provenance; unstable weathering pedogenic process reflects rock–forming features after accumulation dusts. Sr Pb can be as geochemical indicators respectively to provenance process.
