拉斑玄武岩

The SiO2 saturability of volcanic rocks of Xishanbulake Formation and Shuiquan Formation is lower than that of tholeiite of Zhamoketi Formation.

西山布拉克组和水泉组火山岩的SiO2饱和度低於扎摩克提组拉斑玄武岩。

Tholeiite has a zircon SHRIMP U-Pb age of 352 Ma, suggesting that the formation of the ophiolites may have continued till the Late Devonian-Early Carboniferous.

拉斑玄武岩 SHRIMP 锆石年龄352 Ma ，说明蛇绿岩的形成可持续到晚泥盆世—早石炭世。

Through the restoration of the metamorphic rocks, we conclude that the protolith are principally volcanic rocks. The volcanic rocks in the area evolved from the tholeiite series to the calcalkaline series, along with some terrestrial clastics.

通过对变质岩的原岩恢复，得出其原岩主要为火山岩，具有从拉斑玄武岩向钙碱性火山岩演化的特点，局部有陆源碎屑的加入。

Petrographic and REE and trace element geochemical studies of these rocks and Nd isotope analysis of amphibolite indicate that the protoliths of the Mengjiatun Formation complex are sandstone, mud-rich sandstone and island arc tholeiite.

对这些岩石的岩相学，稀土元素，微量元素地球化学的研究和斜长角闪岩Nd同位素的初步分析，表明孟家屯岩组的原岩建造为一套砂岩，富泥质砂岩和岛弧拉斑玄武岩组合。

The feature of earth chemistry of volcanic rock in Xiangshan Group reflects that it belongs to the series of oceanic tholeiite in oceanic spreading tectonic environment.

结果 香山群的时代划归为中晚寒武世较合适；香山群主体是一套由板岩、细、粉砂岩和砂岩组成的浊积岩系，其砂岩类型主要是长石石英砂岩、细粒石英砂岩和粉砂质石英砂岩，前寒武纪变沉积岩和花岗片麻岩为主要碎屑来源和物源区组成；砂岩的岩石地球化学特征指示香山群属发育在被动大陆边缘斜坡环境中的沉积物，火山岩岩石地球化学特征反映其应属大洋扩张构造环境下的大洋拉斑玄武岩系列。

Two REE distributed pattern, LREE-depleted and flat, which display a specific character of typical mid-ocean ridge tholeiite, indicate that primary magma may be derived from near primary or a typical large ion lithophile element-depleted mantle.

岩石稀土元素配分模式可分为LREE平坦型和LREE亏损型两类，指示了其原始岩浆起源于近原始或典型的大离子元素亏损型的地幔，为典型的大洋中脊拉斑玄武岩的特征。

Through the contrast analysis on the chemical constitution of the magnetic iron ore and the plagioclaseamphibolite in Nanling ultra poor magnetite, and the analysis of graphs of and (FeO+Fe2O3+TiO2)Al2O3MgO, combining the geological features of mining area and the ore body characteristics, the conclusion can be drawn as follows: the plagioclaseamphibolites including magnetite and the plagioclaseamphibolite in Nanling mining area are formed from the oceanic tholeiite with rich iron after the deteriorating, and their genesis types should be the ultrapoor iron deposit of weathered residual origin.

通过对南岭超贫磁铁矿的磁铁矿石、斜长角闪岩化学成分的对比分析，结合矿区地质特征和矿体特征，对矿体进行n-n和w( FeO+Fe2O3+TiO2)-w(Al2O3)-w 图解分析，结果显示南岭矿区的含磁铁斜长角闪岩和斜长角闪岩是大洋富铁拉斑玄武岩经变质作用而形成的，矿床的成因类型为风化残积型超贫铁矿床。

The crustal sequence of Shexian ophiolites belongs to the transitional series behaeen calc-alkaline basalt and tholeiite and all through has similar trace elements and REE ratios and chondrite-normalized REE patterns, with high enrichment of large-ion lithophile elements and LREE.

歙县蛇绿岩壳层组合属于钙碱性和拉斑玄武岩间过渡系列，具类似的微量及稀土元素比值和稀土元素配分模型，且大离子亲石元素和LREE高度富集。

The greenstone belt is a typical volcanic-sedimentary formation formed by metabasic-acid volcanic rocks and partly metasedimentary rocks. The bimodal volcanic rocks are mainly tholeiite, which transforms upward into calc-alkali volcanic rock series.

绿岩带为典型的变质基性－酸性火山岩及部分变质沉积岩系构成的火山-沉积建造，火山岩以拉斑玄武岩为主，向上过渡为钙碱性火山岩系列，表现为双峰态型特点。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
