Assuming that the UHP metamorphism occurred at 228 Ma, the exhumation ( uplift) rate of UHP metamorphic rocks are estimated at approximately 3.63 mm/ a before diorite-porphyrite intrusion and approximately 0.03 mm/ a after diorite-porphyrite intrusion respectively.

假定超高压变质作用发生于228Ma，推算出闪长玢岩侵位前超高压变质岩的折返速率大致为3.63mm/a，闪长玢岩侵位后超高压变质岩的折返（剥蚀）速率大致为0.03mm/a。

New understanding of porphyrite type iron ore deposits acquired through inclusion studies

根据矿物中包裹体的研究对玢岩铁矿的新认识

The mineral-bearing hydrotherm which separated from the granodiorite porphyry magma entered into the fissures of the top part of the diorite or granodiorite porphyry. In this process, the atmospheric water dissolving formation minerals in infiltration process mixed with the original magma, and formed the mixed-mineralization fluids.
