摘要

The discovery of ultrahigh-pressure metamorphic rock in the French Alps (Chopin, 1984) sparked a world-wide search for similar rocks. The presence of coesite in such rocks suggests that crustal rocks may be subducted to depths of at least 80 km. Wang et al. (1989) discovered coesite bearing assemblages in the Dabie Mountains in Central China. Another locality, were such rocks were found was the southern margin of the Qilian mountain belt, located in the northwestern part of China (Yang et al., 2001). The discovery of the ultrahigh pressure metamorphics in this locality prompted intense research on the geological and tectonic setting of these occurrences. Within this framework, a joint project between the Chinese Academy of Geological Sciences and the National Cheng Kung University was carried out in 1998-2003. The present issue is a collection of papers reporting the results. Perusal of these papers shows that tectonic reconstructions are based to a large extent on the interpretation of geochemical and isotope data. This in turn begs the question, whether we can currently interpret geochemical data with sufficient confidence. Nevertheless, the picture that emerges is internally consistent and may be summarized as follows.
