摘要

The intermediate acidity volcanic rock which spread in west Keguqin mountain of middle Tianshan mountain in Xinjiang, is the outcome of upper carboniferous structure-magma effusion, it reflect an important structure-volcano geologic event in this area. In the study for its rock and geochemical character, it shows that the volcano effusion event formed in active continental margin structure environment, has double character of continental rift volcanic sequence and island arc volcanic sequence, is the typical lag arc volcanic rock.
