Abstract：For the deep depth and partial melting phenomenon of lithosphere structure or deeper mantle discontinuity of mid-ocean ridge and marginal sea spreading ridge,it's difficult to obtain seismic signal with active source seismic method.Meanwhile,there are no permanent seismic stations in the sea basin,and there is a low precision when using the natural seismic surface wave to study.This paper puts forward the suggestion that study lithosphere structure and Mantle Transition Zone (MTZ)of mid-ocean ridge or spreading ridge with the Ocean Bottom Seismometer(OBS)passive source receive function,which is based on the analysis of OBS natural earthquake observation.The relevant issues,methods and technology route about the OBS passive source receiver function are well described.Finally,the paper introduces an experiment plan of OBS passive source observation at ultra-slow spreading Southwest Indian Ridge.
