| 英文摘要 | There are widespread similar to 1. 9Ga plutonic rocks in DPR Korea, which can be subdivided into three series, a porphyritic granite series (I-type granites, e. g., the Myohyangsan pluton, 1900 similar to 1840Ma), S-type granite series (e. g., the Gasan pluton, a 1862 +/- 5Ma zircon U-Pb age is obtained) and the syenite series (the Ryongpo pluton as an example, a 1857 +/- 2Ma zircon U-Pb age is obtained). The I-type granite series is called the Myohyangsan Complex by local geologists, and is characterized by megacrysts of K-feldspar and is closely occurred with the granulite facies meta-volcanics/sediments; whereas the S-type granite series is called the Ryonhwasan Complex, and is characterized by containing garnet and cordierite and is distributed in the high-grade paragneisses. This indicates that the S-type granites could be originated from paragneisses; while the porphyritic granite series (I-type granite) could be associated with the volcanic-containing supracrustal rocks. The syenite series is called as the Sakju Complex by local geologists, and is limitedly distributed in Sakju and Tokchong-Chongju and the neighbouring Liaodong Peninsula, and appears as stocks. These plutons are slightly older or basically coeval with the metamorphism timing of the regional amphibolite-granulite facies metamorphism (a 1844 +/- 2Ma zircon U-Pb age is obtained from paragneiss of the Jungsan 'Group'). The syenite series could be originated from high-pressure melting of crustal materials. There are also similar series of plutons in the neighboring Liaodong-Jinan and Jiaodong areas, where the similar to 2. 1Ga igneous rocks are more prominent. There are also widespread similar to 1. 9Ga plutons in southern Korean Peninsula; however, these are dominantly porphyritic granites with a few charnockite and anorthosite. It may indicate different basements for the north and south part of the peninsula, i. e., they may belong to different paleo-continents (North and South China blocks). The widespread 1. 9Ga I-type and S-type granites with locally syenites and some mantle-derived igneous rocks in northern Korean Peninsula are coeval with the regional high-grade metamorphism. Considering the existence of Archean basement, we suggest that the region was possibly similar to modern continent marginal arc at the Paleoproterozoic. |
