摘　　要：The muscovite in Hongzhen, Anhui Province, is identified as 2M1-phengite by x-ray diffraction and electron microprobe. Its structure, composition and paragenetic minerals imply medium pressure metamorphism.The muscovite in Hongzhen, Anhui Province, is identified as 2M1-phengite by x-ray diffraction and electron microprobe.
