摘　　要：Enstatite chondrites are the product of nebular condensation-agglomeration under extremely reducing conditions. They can be classified into two groups: the high-Fe(EH)and the low-Fe group(EL). The former can be further divided into three types, EH3, EH4 and EH5, while the latter all belong to EL6 type. Unequilibrium enstatite chondrites approximately represent the primordial celestial materials formed through partial nebular condensation-agglomeration and accretion in inner solar system, while the equilibrium ones are be-
