拉斑玄武岩

Based on major and trace elements and isotope geochemical data, it is inferred that Sandouding suite is formed by magma melting of Late Archeozoic continent tholeiite source, and its geochemical variation is controlled by hornblende fractional crystallization. Besides fractional crystallization, the geochemical variation of Huanglingmiao suite is related to the mixing between dacitic magma and felsic magma. Dalaoling suite is probably derived from early Precambrian volcanics.

根据岩石化学和同位素组成推断，三斗坪岩套的源岩主要是晚太古代大陆拉斑玄武岩，母岩浆相当于英安质，岩套内的成分变化主要受角闪石分离结晶作用控制；黄陵庙岩套除受分离结晶作用影响外，成分变化主要与英安质母岩浆和某种长英质岩浆的混合有关；大老岭岩套的源岩亦为早前寒武纪火山岩。

However, the Nb/Ta ratios lower than chondrite value (～17) in eclogites are inconsistent with previously proposed Nb/Ta high in subducted oceanic crust to complement the mass balance of Nb and Ta in the evolution of continental crust.

Also on the analysis of geochemical data, it is sugested that the composition of eclogite is not simple butacombination of terrestriaI tholeiite and basic volcanic tuff and marl.

The geochemical characteristics of basic to intermediate-basic igneous rocks indicate that they belong to a tholeiite suite. Their chondrite-normalized REE patterns are of nearly flat and slightly LREE-enriched type, and their primitive mantle-normalized and MORB-normalized trace element spidergrams are generally similar; the LILEs Cs, Ba, Sr, Th and U are enriched, while Rb and K and the HFSEs Nb, P, Zr, Sm, Ti and Y are depleted. All these show comagmatic evolutionary and genetic characteristics.

The PGE distributive patterns are the PtPd type, the Pt/Pd ratios of 0.32-0.68 are between the values of enriched sulfide tholeiite (0.38) and primitive upper mantle (1.36), and the similarity of partition patterns of chondritenormalized REE, MORB-normalized trace element and primitive mantle normalized PGE for the rocks of the three phase zones, indicate the Baimazhai intrusive body I formed by the evolution, liquation, intrusion and diagenesismetallogenesis of basaltic magma.

铂族元素配分模式为Pt-Pd型，w/w比值为0.32~0.68，介于富硫化物拉斑玄武岩(0.38)和原始上地幔(1.36)之间，以及稀土元素配分模式、微量元素蛛网图和铂族元素配分模式中不同岩石配分曲线的相似性揭示3个相带不同岩石之间的高度一致性，展示基性-超基性岩形成于玄武质岩浆演化、熔离及岩浆一次性侵入、分异成岩成矿的特征。

By studying on isotopic chronology, terrane configuration and imaging logging data, the diabase intrusion in Zhanhua Sag is formed by tholeiite magma emplacing in Shahejie formation stratum on the rift tension background Lower Tertiary in North China. The diabase intrusion of Luo151 is composed possibly of three periods magma emplacement.
