Recent situation of researches on ophiolites and some problems concerning the ophiolites in south China

Ophiolite is an important evidence to determine the palaeo-plate boundaries and shows an important geotectonic significance since 1970s,thus when the concept of ophiolite was proposed,it has become one of the most important object of study for geologists.With the development of geochemical techniques and implement of deep sea drilling program(DSDP) and ocean drilling program(ODP),further studies on ophiolites have been made and a great progress has been acquired in recent years,however many new problems have been raised at the same time.This paper mainly discusses the recent development in the study on ophiolites and analyzes the present situation of researches on ophiolites in south China.In addition,some existed problems have been preliminarily discussed.
