| Abstract: | A study on geochemical character of high-pressure quartzo-feldspathic granulite in Songshugou area, east Qinling, shows that its protolith is composed mainly of graywacke or arkose, and a little of subalkaline acid volcanic rock or magmatic rock with characteristies of mantle source. Its paleotectonic setting is similar to that of active continental margin. |
