It shows that the magma forming the syenite in the Luzong basin was derived from a deep source, most likely resulting from the partial melting of an alkali basalts along the deep fault, and obviously contaminated by continental crust material.

反映了庐枞盆地正长岩类成岩物质来源较深，是来自富集地幔的碱性玄武岩浆在沿深大断裂上升侵位过程中，受到部分陆壳物质的混染而成。

The material for formation of the granitoids isderived from mixing sources of crust and mantle, with decreasing in crust-derived componentsfrom early to late.5. The tectonic setting for formation of the Mesozoic granitoids in the region isdefined as a post-collisional setting. The occurrence of a small part of rocks with characteristics ofcollisional or anorogenic granitoids provides evidence for the continuous process oftransformation of tectonic regime from collisional through post-collisional to anorogenic.6. Themultiple cycles of mantle-derived magma underplating caused by the multiple stages oflithospheric thinning in the Mesozoic result in the partial melting of middle to lower crust orcrust-mantle syntexis to form magmas. The crystallization of these magmas emplacing afterfractionation is responsible for the formation of the Mesozoic granitoids in this region.

形成花岗岩类的成岩物质来自壳幔混源。5、河南省西部地区中生代花岗岩类成岩构造环境为碰撞后环境，部分岩石具有碰撞期或非造山期花岗岩的某些特征，表明碰撞后阶段既是碰撞造山过程的延续，又是向非造山环境的构造转换时期，因而其岩浆活动在一定程度上仍然继承了碰撞前消减时期和碰撞时期已经活化的岩浆源区性质。6、研究表明，区内中生代多阶段的岩石圈减薄作用引发多旋回的幔源岩浆底侵以及中下地壳的部分熔融或壳幔同熔，由此形成的岩浆经分异演化后侵位可以形成区内的中生代花岗岩类。

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。

The Mg-rich volcanic rocks consist of high-Mg decite and high-Mg basalt which are the products of congenetic magma,in Ashele are, Xinjiang. In comparison with tholeiite, their εNd are obviously low, implying that they are contaminated by the oceanic sediments during their forming process.

阿舍勒富镁火山岩由高镁英安和高镁玄武岩组成它们可能是同源岩浆的产物，与共生的拉斑玄武岩相比，富镁火山岩钕同位素明显富集，反映在其形成过程中受到了大洋沉积物的混染。

The research has shown that the ourgassing of the Earth can be regarded as a key link,which connects the separated branches of the Earthscience into a whole mega system The essence of Earth outgassing is the expelling of mantle ichorspontaneously and radiately from the interior of the Earth,resulting in five gas spheres and gas geodynamics The upwelling of HANCONS makes the solid mantle and crust to ulcerate by the alkaline mesomatism,alteration and magma formation, and the ...
