| Abstract: | There are a series of Paleozoic strata in the Naxi area of Fuding City,Fujian Province.Based on the lithological features,fossils,stable isotopes and structural features of the strata and comparison with other basements,it suggests that there are some features of flysch formation and geosynclinal sedimentation in the strata,but it belongs as a whole to a platform cover deposit which was well developed in Cathaysia,that the Paleozoic epimetamorphic rocks can be divided into upper and lower parts,and that the upper part belongs to Upper Paleozoic Group,which has analogy to synchronous strata in Zhejiang Province along the Fuding Ningbo taphrogeosyncline,and the lower part belongs to Lower Paleozoic Group (Ordovician Devonian),which has analogy to synchronous strata in Guandong,Hainan,Zhejiang provinces.The sediment in the surveyed area is made up of normal fragments and less pyroclast.The sedimentary environment is taphrogeosyncline formed in the course of Cathaysia splitting and the fragments are derived from the adjacent microcontinent block in Cathaysia. |
