Abstract

Abstract

The upper basement of the Cathaysia block in Zhejiang and Fujian provinces consists mainly of the Neoproterozoic Longquan Group, Mamiansban Group, and Wanquan Group. These three groups exhibit similarity in rock assemblage as well as major and trace elements geochemistry. They are the main components of the uniform upper basement of the Cathaysia block, consisting mainly of schists, leptynites, quaterizes and marbles. Schists and the leptynites have variable composi-tions, with SiO₂ contents ranging from 52.89% to 75.03%, TiO₂ from 0.48% to 1.05%, Al₂O₃ from 9.19% to 20.3%, ∑REE between 149×10^-6 and 323×10^-6, δEu values between 0.34 and 0.80, and (La/Yb)_N values between 7.96 and 15.6. The REE patterns display medium to high negative Eu anomaly with obvious fractionation between LREE and HREE. The quartzites have different compositions, with SiO₂ contents varying from 95.49% to 97.44%, and relatively low ∑REE contents (8.89× 10^-6 to 15.1 × 10^-6). It is proposed that protoliths of the schists and the leptynites are wackes and clay rocks, whereas protoliths of the quartzites are ferruginous silica rocks, mainly quartz-feldspathic; and some protoliths show geochemical characteristics of ancient allochthonous sediments. The meta-sedimentary rocks of the Longquan Group, Mamianshan Group, and Wanquan Group were probably formed in an environment of arc-active continental margin. The lower maturity implies that they are near field sediments, similar to the metamorphic rock system of the lower basement in this area (Paleoproterozoic Tianjingping Formation, Badu Group, Chencai Group and Mayuan Group), analogous to the upper crustal rocks.
