Data are presented on a detailed petrographic and mineralogical investigation of chondrules and their minerals in polished sections of the Indarch EH4 enstatite chondrite. According to the composition of the main minerals and their associations, the Indarch EH4 chondrules can be subdivided into porphyritic and nonporphyritic groups. The porphyritic chondrules are characterized by the presence of two types of clinoenstatites which differ by the content of impurities and by andesine-labrador feldspar mesostatis of variable composition. Nonporphyritic chondrules have albitic mesostasis. Results indicate that two (or more) types of chondrule precursors with different compositions took part in the formation of the Indarch chondrite.
