| 英文摘要 | The Late Neoarchean witnessed the cratonization of the North China Craton (NCC) through amalgamation of several micro-blocks to form a coherent basement. The Archean rocks in this craton have experienced varied grades of regional metamorphism ranging up to upper amphibolite and granulite facies at similar to 2500Ma. However, medium- and low-grade metamorphosed (greenschist to lower amphibolite facies) volcanic-sedimentary rocks are widely distributed in northern Hebei Province. It includes Hongqiyingzi supracrustal rocks in the Humaying district and the low-grade metamorphosed part of the Dantazi supracrustal rocks in the Dayinshan district. The Hongqiyingzi supracrustal rocks in the Humaying district consist mainly of meta-mafic volcanic rocks, epidote amphibolite, amphibolite, garnet amphibolite, hornblende-plagioclase gneiss, biotite-plagioclase gneiss, biotite monzonitic gneiss, quartz schist and magnetite quartzite. SIMS zircon U-Pb ages of 2486 +/- 18 Ma (MSWD =1. 4) and 2507 +/- 37Ma (MSWD = 2. 0) are interpreted as the formation age of the amphibolite and biotite-plagioclase gneiss, repectively. The Dantazi supracrustal rocks in the Dayinshan district consist mainly of low-grade metamorphosed volcanic rocks, biotite-quartz schist, amphibolite, magnetite quartzite and marble. SHRIMP zircon U-Pb ages of 2490 +/- 19Ma (MSWD = 2. 0) and 2502 +/- 8Ma (MSWD = 0. 83) are interpreted as the formation age of the meta-baslt and meta-dacite, respectively. Therefore, the medium- and low-grade metamorphosed volcanic sedimentary rocks in the northern Hebei region were formed in the Late Neoarchean. Our new data, combined with the 2511 +/- 2503Ma Qinglong low-grade volcanic-sedimentary rocks in the eastern part of the NCC suggest that the medium- and low-grade metamorphosed volcanic-sedimentary rocks distributed not only in the central area but also in the margin of the NCC. The protoliths of these medium and low-grade metamorphosed supracrustal rocks were deposited on Archean high-grade metamorphosed complex within the craton as a cover sequence, marking the cratonization of the NCC. |
