| Abstract: | Characteristics of metamorphic rock series of the Huodiya Group in the South Michangshan Mountains are discussed in terms of petrology and geochemistry. The study shows that the Huodiya Group is composed of a lot of parametamorphic rocks and a bit of volcanic rocks. Pn-Pb Age values for zircon and field geology indicate that the Huodiya Group belongs to Middle-Upper Proterozoic Subera. |
