Thepetrofabrics, mineral composition and abundances of the trace elements in the dunite indicate that the inclu-sions were derived from the upper mantle and are the residues of high-degree partial melting of mantlepeirdotite. The study of trace elements in the inclusions and their host rocks shows that the magma was origi-nated from the mantle which was enriched in incompatible elements by mantle metasomatism prior to the par-tial melting.展开更多

[Method] According to the annual and seasonal rainfall data in Xingtai, Nangong, Shahe and Neiqiu during 1963-2010, by using the interannual variation rainfall line chart, trend chart and climatic variability, the variation trend of rainfall in Xingtai area in recent 48 years was analyzed. [Result] The annual rainfall in Xingtai area during 1963-2010 presented yearly decrease trend, and the decrease velocity was 18.0 mm/10 a. The annual rainfall in Xingtai, Nangong, Shahe and Neiqiu roughly presented same trend (linear decrease). Except spring rainfall in Xingtai area in recent 48 years slightly increased, the rainfall in summer, autumn and winter all presented linear decrease trend. The decrease velocity of summer rainfall was the maximum. The decrease of summer rainfall played decisive role in rainfall decrease of the whole year. The decrease trend of winter rainfall wasn’t as significant as that of autumn rainfall. [Conclusion] The research provided theoretical basis for studying climatic variation characteristics in Xingtai area under the climatic warming background.展开更多
