Abstract
The metamophic peridotite of ophiolite belt in Mt. Ailao is composed o f Iherzolite and harzburgite. The former shows the charateristics of p rimary pyrolite and the latter shows those of deleted (relict) pyrolit e. By partial melting of Iherzolite, two primary magmas: tholeiitic ma gma and picrite-basalt magma are formed. The former evoluted into gabb ro-diabase-pyroxenic basalt rock series and show the characteristics o f MORE; while the latter evoluted into gabbro-diorite-albite basalt-pi crite basalt one, and show the characteristics of para-MORB.
