Abstract Subalkali magma was formed under environment of subduction of pacific plate in Mesozoic, inherited activity of Chongli-Chicheng fault and strengthening of interaction of crust and montle in plate. There are four independent series of rock with eleven kinds or rock in subalkali rocks zone. The forming mechanism of the magma is partly melting of deep material, multiple activity of magma, emplacing along regional great fault forming E-W trending linear batholith. The subalkali complex zone is related closely with gold deposits in time and space.
