摘要

Based on the field work, this paper focuses on petrology and geochemistry of the metabasalts from Sijizhuang, Qingshicun and Hebiancun formations in Hutuo Group. The results show that the basalts are rich in TiO_2,TFeO, and poor in MgO, suggesting the features of evolved basic magma. With high concentration of total REE contents, the LREE is moderately enriched, but the Eu anomaly is weak (or slight). The contents of Cr,Ni in the basalts change greatly and are positively corrrelated with Mg#. In spidergrams to normalized in NMORB, the basalts in Hutuo group are different from IAB in strongly negative Sr anomaly, Nb, Ta and Ti anomaly in some samples, but the Zr,Hf anomaly is absent.
