| Abstract: | As many as 2775 samples of metamorphic rock. and metavolcanic rocks were systematically collected from Archean high-grade metamorphic terrains and gran- ite-greenstone belts within an exposed area of about 120 000 km2 in North China Plat- form. The samples were then mixed into 339 composite analytical samples and were ana- lyzed by 15 kinds of method using certified reference materials for data quality monitor- ing. Average contents of 13 major compositions and 64 trace elements for 26 metamor- phic rocks,such as gneiss, leptite, granulite, and amphibolite were given. |
