Abstract
On the basis of new data on melt inclusions in clinopyroxenes, we have established the physicochemical conditions (magma compositions, temperature, and pressure) of formation of boninites in ophiolites of the Dzhida zone (northern Mongolia) and have determined the parameters of generation of primary magmas (T = 1400-1500
