英文摘要	Ultramafic and gabbroic rocks sampled from the mid-atlantic ridge exposed on a detachment fault at the logatchev massif south of the fifty-twenty fracture zone (15 degrees 20'nfz) are serpentinized peridotites, soapstone and altered gabbros. based on the detail petrological and mineralogical studies of serpentinized peridotite and gabbro samples, in conjunction with already existing mineralogical and isotopic data, we proposed a model of serpentinization at different depths beneath the 15 degrees 20'nfz and to provide a framework for the serpentinization of many abyssal peridotites in slow-spreading environments. at the main stage of serpentinization model, there is possibly a transition zone of serpentine formation from antigorite to lizardite and chrysotile, leading lizardite to be dominant in serpentinized abyssal peridotites. present model, also propose that the initial depth of serpentinization should be much deeper than moho.
