The protoliths of the chlorite-actinolite schist were mainly volcanic-sedimentary rocks enriched in basalt. The chlorite-actinolite schist and the altered pillowbasalt are characterized by high contents of TiO5, P2O5 and MgO, LREE-enriched patterns with negative Eu anomalies, and "tumescence" patterns for trace elements with enrichment in Nb, Ta and Ti; these are typical characteristics of "OIB-type" alkaline basalt.

At western segment of Altyn Tagh tectonic belt, The eclogites and khondalite series were recognized in Altyn Group (Early Proterozoic?) Which had been thought prviously that it consists of high greenschist facies and lower amphibolitic facies metamorphic rocks. They crop out at the northern slope and southern slope of Altyn Tagh Mountains respectively.
