| Abstract: | According to the regional survey information of Gongxi of the scale of 1∶50,000,the macro-micro features of the extra-low metamorphic rock of Sinian-Lower Cambrian in Gongxi of Hunan and Pingdi of Guizhou are narrated,combine with the geological background of Sinian-Lower Cambrian,the extra-low metamorphism and the extra-low metamorphic rock are discussed.It affords new information for the study and division of regional metamorphism and metamorphic band in Guizhou. |
