%X The low-grade metasedimentary rocks of the Fuzikuang Formation, Penglai Group in Changdao, Yantai, Shandong Province are mainly composed of metamorphic quartz sandstones, with metamorphic siltstone and mud rock intercalations. The depositional age of the Penglai Group has long been dabeted. Based on the U-Pb age spectrum of detrital zircons, the authors conjecture that the age of the Fuzikuang Formation, Penglai Group in Changdao is Neoproterozoic. There are two age peaks, ~1600Ma and 1200~1100Ma, in the age spectrum of the detrital zircons. The younger age peak shows that the Fuzikuang Formation was sourced from a provenance with typical Greenville-period tectono-thermal events, which is different both from the North China and Yangtze blocks in geological evolution characteristics. Hence further work is needed to decipher the special source region.
