| 英文摘要 | In the Carboniferous-Permian coal formations in Datong area lots of basic dike warms occur. They are mainly carbonatites and basic-ultrabasic lamprophyres. The strata, relationships as well as Rb-Sr and K-Ar isotopic chronology show that the dike swarms were formed at Late Triassic (229Ma). The Sr,Nd isotopic ratios and Rb/Sr ratios of carbonatites and lamprophyres indicate that they were originated from a crustal-mantle mixing type reservoir. The stable element ratio of compatible and incompatible elements implies that they are liquid immiscible congeners coming from a primitive magma consisting of mixed carbonatites and silicates. Examination of the conditions reveals that they were formed in extensional tectonic sittings and controlled by structures at different levels. Study on Datong dike swarms will play an important role in further understanding the evolution of the Early Mesozoic lithosphere in North China. |
