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。

The results show that when the depth gradually reduces, pH values gradually increase, but conductivities and (superscript – subscript 3) content gradually reduce. There are also obvious differences between the groundwater in loess, alluvial deposit and acidity rock in the south of Chang'an, which relates to the depth, the characters of loess, the lixiviation and the evaporation. The element content of groundwater is high in the loess tableland, so it's fitter for drinking than the groundwater in the Cuihua mountains, which is of acidity and low element content.

结果表明，长安南部黄土塬随着层位的降低，pH值有逐渐增大趋势，电导率和HCO(上标–下标 3)含量有逐渐减少的趋势；黄土地下水、冲积层地下水和酸性岩石地下水的化学成分存在明显差异，这与其理深、地层性质、溶滤与蒸发作用不同有关；长安南部少陵源黄土地下水元素含量较高，比呈酸性、元素含量低的翠华山泉水更适于饮用。

On the basis of the study on the petrology, Trace element, and isotopic geochemistry, the primary magma of volcanic rocks can be divided into two series according to their originated rocks and degree of partial melting. One is the basanite-alkaline basalt-Olivine tholeiite magma series, which are generated by partial melting from spinel Iherzolite; the other is nephelinite magma-alkaline picritic basalt magma, which are generated by partial melting of the garnet Iherzolite.

岩石化学、微量元素、同位素地球化学证据都表明，华北、华南地区的火山岩根据源岩和局部熔融程度的不同，可以分为两个原生岩浆系列：一个是源岩为尖晶石二辉橄榄岩，随着局部熔融程度的增加，形成的碧玄岩岩浆-碱性玄武岩岩浆-橄榄拉斑玄武岩岩浆；另一个是源岩为石榴石二辉橄榄岩，随着局部熔融程度的增加形成的霞石岩岩浆-碱性苦橄玄武岩系列。

The petrochemistry and geochemistry of Mesozoic volcanic rocks mainly indicate the environmental characteristic of distending structure which bears on orogenic belt. The process of the evolution that earth crust keeps thinning reflects that it is still in the time of extruding orogenesis. Only during the intermittence or relaxation stages of extruding orogenesis, the volcanic eruption of neutral rock and acidic rock were formed in the situation of relative distending structure.

中生代火山岩的岩石化学、地球化学特点，主要显示了与造山带有关的拉张构造环境特征，而地壳由薄变厚的演化过程，则反映了该时期仍以挤压造山作用为主，只是在挤压造山作用的间歇或松驰阶段，相对处于拉张构造环境的情况下，形成了中酸性岩的火山喷发。

In this paper, though the field geological investigations, and studies of element-isotope geochemistry, mineralogy and the geo-chronology, combining with the regional geotectonic analysis, the geochemical characteristics and petrogenesis of the mafic dikes from the coastal areas of Guangdong Province and Hainan Island are discussed, mafic magma episodes and mantle characteristics are analyzed, and the relationships between mafic magmatism and lithosphere evolution are studied.

本论文通过野外地质调查和一系列配套的岩石化学、微量元素、同位素地球化学、矿物学及年代学方法，结合区域地质构造分析，对广东沿海地区及海南岛基性岩脉的地球化学特征、成因、基性岩浆活动期次、地幔源区地球化学特征，以及岩石圈结构特征、形成机理和演化等进行了探索性的研究，得出以下几点认识： 1。

Petrochemistry, trace element, REE and isotope geochemistry of quartz syenite porphyry, quartz diorite porphyry, rhyolite, and biotite granite indicate that they belong to series Ⅱ granite defined by Wangliankui (l972), but they have some characteristics of series Igranite, which shows adding of recycle upper-crust materials.

岩浆岩岩石化学、微量元素、稀土元素及同位素地球化学特征表明，莲花山矿区的石英正长斑岩、石英闪长玢岩、流纹岩和黑云母花岗岩属于王联魁(1972)所划分的系列Ⅱ花岗岩(相当于Ⅰ型磁铁矿系列花岗岩)，但也具有系列Ⅰ花岗岩的某些地球化学特征，表明岩浆中有再循环上地壳物质的加入。

The comparative studies of lithogeochemistry for the volcano-intrusive complexes both from Jiulongzhang and from xiangshan reveal that the chemical compositions of the volcano intrusive complexes in the two areas are very close, and the trace element spidergrams and REE patterns basically coincide with each other. It is also shown that the two volcano-intrusive complexes have the same source features and the active continental margin tectonic settings. At the same time, it is found that, from early volcanic magma activities to later intrusive magma activities, the content of SiO2 and the Rb/Sr ratio decreased, on the contrary, the content of MgO and the ratios of K/Rb, Ba/Rb and LREE/HREE increased. It is shown that the hypabyssal or ultra-hypabyssal intrusives are not the products of the volcanic magmatic differentiation.

两地区的火山－侵入杂岩的岩石化学成分及其变化特点极为相近，微量元素蛛网图和稀土配分型式也基本一致，它们具有相似的岩浆过程和统一的活动陆缘构造背景；同时，从早期火山岩浆活动到晚期浅成－超浅成岩浆侵入活动，其w(SiO2)和w/w的值降低，而w以及w/w、w/w和w/w的值增高，晚期浅成－超浅成侵入岩与早期火山岩没有直接的分异演化关系。

The variations of iron species not only affect the lithological properties of sedimentary rocks, such as color, but also reflect the paleoenvironments of the sedimentary rocks.

The others include 1 martian meteorite, 1 HED meteorite and 6 L3 ordinary chondrites. These 20 equilibrated ordinary chondrites are classified into chemical groups of H, L and LL, respectively, based on mean Fa content of oli-vine, mean Fs of low - Ca pyroxene and abundance of Fe-Ni metal.

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
