英文摘要	Samples were systematically collected from metamorphic basic volcanic rocks in the Jiehekou and Xiyupi areas on both sides of the Luliang Mountains, Shanxi Province and analyzed for their major elements, trace elements and rare earth elements (REE). The geochemical characteristics of their major, trace and rare-earth elements indicated that the metamorphic basic volcanic rocks in this area were emplaced in the tectonic environment like a modern continental rift. Sm-Nd and Rb-Sr isotope chronological studies demonstrated that the Jiehekou Group metamorphic basic volcanic rocks were formed during the 2600-Ma crust/mantle differentiation event, and were transformed by granulite facies metamorphism during the late Neo-Archaean period (2500 Ma+/-), making the Sm-Nd systematics of the rocks reset. During the late Paleoproterozoic period (1800 Ma+/-) the Rb-Sr systematics of the rocks were disturbed again in response to the Luliang movement. Since the extent of disturbance was so weak that the Sm-Nd systematics was not affected, the age of 1600 Ma obtained from this area seems to be related to local magmatic activities within the craton. Research results lend no support to the idea that the Luliang Group was formed during the Archaean. Instead, it should be formed during the Proterozoic.
