岩浆

The ironrich and silicapoor liquids, commonly different from the low iron and silicarich liquids, are rare on the earth surface. There are not the same, which can be used to explain their petrogenesis at present.

在自然界中与普遍发育的具Bowen趋势的低铁富硅熔体不同，高铁贫硅岩浆非常罕见，也没有直接的现代类比物可以对比以解释其岩石成因。

The study on the mechanism of petrogenesis of high-Fe magnesian magmas is important to understand the tectonic regime of magmas in depth, early evolution of crust, the heterogeneity of lower mantle and the interaction of core-mantle. Meanwhile, it is also most significative for us to understand the petrogenesis of high-Fe magnesian rocks discovered from southern Taihang Mountains and other regions, in China.

其成因机制的研究对于理解其岩浆深部构造背景、早期壳－幔演化、下地幔组成不均一性和核幔相互作用有着重要意义；同时，对于最近在我国南太行山地区及其它地区发现的具有高铁镁特征岩石的研究具有极其重要的意义。

Then the PTt-D paths in different places have been constructed and compared with those of the typical low-pressure and mid-pressure metamorphism both within China and abroad. Based on their similarities and differences and combined with the study on the characteristics and petrogenesis of granitic rocks, the protolith of metamorphic rocks and their tectonic significance, the tectonic setting and the geodynamic mechanism that caused the metamo rphism.

据此构筑各地区的PTt-D轨迹，并与国内外一些典型低压和中压变质地区相对比，分析彼此的共性和特性，再结合花岗质岩浆作用的特征及成因，以及原岩建造及其所代表的大地构造环境等方面的资料综合分析，以确定本区当时的大地构造环境和引起这种样式变质作用的地球动力学机理。

And positive anomaly of Rb,Ba,Sr,etc. The granite emplaced by underplating of granitic magma,which formed through partial melting of sedimentary mainly of arenite,and is typical crust source petrogenesis.

岩体是以杂砂岩成分为主的沉积岩部分熔融形成的花岗质岩浆上升侵位过程中形成的，是一种典型的壳源成因类型。

One of the main purposes of igneous rocks petrography is to get an entire classification of magma and igneous rocks system.

火成岩岩类学研究的主要目的之一在于获得岩浆/火成岩系统的一套完整的分类清单。

In petrology, fenite and fenitization have been identified,and the existence of igneous carbonatite has been confirmed.

在地球化学和矿床成因方面，提出了稀土稀有金属矿化与火成碳酸岩岩浆活动有成因联系的见解。

The precambrian protodiwa was discoveried in China for the first time. In author's opinion, this region experienced a protodiwa staye with drastic Tectono-Magmatic Activiation Similar to the diwa region in phanerozoic thime. This achievement is an important contribution to the diwa theory.

在我国首次发现前寒武纪原地洼区，认为该区在晋宁运动后，经历了一个与显生宙地洼区相似的强烈构造—岩浆活化的原地洼阶段，对地洼学说作出了重要的贡献。

Study on the lithology and petrology (fine-grained cold-quenching ring of the enclaves, the reverse vein, the complex enclaves, the plagioclase phenocryst from both host rock and enclaves that is consist on the crystal form, composition and light, et al.), petrogeochemistry (Y/Nb=2.77～6.82, La/Nb=0.91～4.33, Ba/Nb=0.13～37.86, et al.), Sr and Nd isotope most ISr between 0.7031～0.7041,εNd(t=5.2～7.1 and LA-ICP-MS zircon U-Pb dating (the host rock age is 311±12Ma, and enclaves is 306±7Ma), believe the Huangyangshan pluton is crust-mantle hybrid genesis.

通过岩石学和岩相学（包体细粒淬冷边，反向脉，复合包体以及寄主岩石和包体中斜长石斑晶在形态、成分、光性上的一致性等），岩石地球化学（Y/Nb=2.77～6.82，La/Nb=0.91～4.33，Ba/Nb=0.13～37.86等），Sr和Nd同位素（ISr多数在0.7031～0.7041，εNd在5.2～7.1之间）以及LA-ICP-MS锆石U-Pb测年（寄主岩石为311±12Ma，包体为306±7Ma）综合研究认为黄羊山花岗岩是壳-幔源岩浆混合成因的。

Through analysis of the experimental data about ultrapotassic rocks, typeI ultrapotassic rocks came from the source region of phlogopite harzburgite that had undergone metasomatism of fluid enriched in silica and potassium; while the source region of typeⅢ potassicultrapotassic volcanics is carbonated peridotite mantle bearing potassic amphibole.

综合超钾质岩石的实验资料，可知区内I型超钾质岩的源区以富硅、富钾流体交代形成的金云母方辉橄榄岩为主；Ⅲ型钾质超钾质岩浆源区则以斜辉橄榄岩地幔为主。
