英文摘要	There are three groups of pillow volcanics in the Dachadaban ophiolite. Group 1 is typical boninite, enriched in Si, Mg and depleted.in Ti, HREE and.HFSE; group 2 is the evolved boninite, slightly higher abundance of Ti, HREE, HFSE and.large variation of Mg' due to fractional crystallization; and group 3 is tholeiite with MORE : character. The existence of MORB and boninite indicates;hat the Dachadaban ophiolite was probably formed in island-arc and back-arc environments.
