Based on the electron microprobe (EMP) and laser ablation inductively coupled plasma mass spectrometer (LA-ICP-MS) analyses, the major and trace element features of the feldspars from the Cenozoic trachyandesite of north Qiangtang were discussed in this paper. The results indicated that all of the feldspars exhibited Rb, Sr, Ba and Eu enrichment. Especially, the REE distribution patterns of the potassium-feldspar and the plagioclase were much similar each other.
