经过 ２０ 余年的不懈努力，元古宙蛇绿岩研究已取得了巨大进展。元古宙蛇绿岩的保存特点、多样性、高压超高压变质作用、地质年代学及研究方法（方法论）等几个关键问题尚需进一步探索。我国元古宙蛇绿岩研究应加强构造—岩性的综合研究，并通过同位素测年和地球化学示踪，获取可信的成因信息；同时，还需考虑元古宙洋壳的地球化学特殊性及后期变形变质作用的影响，不能简单套用显生宙蛇绿岩的判别图解和研究方法
After more than 20 years of unremitting efforts, great progress has been made in the study of the Proterozoic ophiolite. Proterozoic ophiolite preservation characteristics, diversity, high pressure and high pressure metamorphism, geochronology and research methods (methodology) and several other key issues need to be further explored. In the study of Proterozoic ophiolite in China, we should strengthen the comprehensive study of tectonic-lithology, obtain credible genetic information through isotope dating and geochemical tracing, and also consider the special geochemical features of Proterozoic crust Sexual and post-metamorphic metamorphism, we can not simply apply the discrimination diagram and research method of the Phanerozoic ophiolite
