| SHRIMP U-Pb Zircon Chronology of Fine-grained Amphibolite in the Mengjiatun Area, Western Shandong |
| Based on studying mineral lithofaces, zircon characteristics and chronology, the authors obtained zircon SHRIMP metamorphic age of 2 604±11 Ma for fine-grained amphbolite from Mengjiatun area of western Shandong. According to metamorphic ages of Mengjiatun Formation and other magmatic ages of western Shandong, it is concluded that intense geological movement took place from 2 650 Ma to 2 600 Ma, which is quite different from other regions in the North China platform. Therefore western Shandong has its unique geological evolution history in Early Precambrian. |
