This rock zone, with a NE striking, the whole length of 1 400 km and the width of 100～150 km, is characterized by not onlyalkaline rocks (analcite biotite olivine melilitites, leucititic alnoites, nephelite syenites, aegirite augite syenites, melanite syenites, riebeckite syenite and aegirite bearing quartz syenites) and alkaline granite (riebeckite granite, and aegitite augite riebeckite granite), but also a lot of syenites, monzonites and alkaline feldspar granites or miarolitic K feldspar granites.

The meta-peridotite consists of dunite, harzburgite, lherzolite, feldspar-bearing lherzolite and garnet-bearing lherzolite and contains residual spinel with Cr#s [100*Cr/] of 30-57 and Mg#s [100*Mg/(Mg+Fe2+)] of 50-75, indicating an Al- and Mg-rich series.
变质橄榄岩主要为纯橄岩、方辉橄榄岩、二辉橄榄岩、含长二辉橄榄岩和含石榴石二辉橄榄岩，岩石中残余尖晶石的Cr'值=100×Cr/(Cr+Al为30～57，Mg'值=100×Mg/(Mg+Fe2+为50～75，指示一个富Al和Mg成分系列。

In respect of mineralogy and petrology as well as strontium isotope, the Pl-lherzolite exhibits some features of transition from the cumulates to the mantle peridotite.
在矿物成分、化学成分及锶同位素等力面，含长二辉橄榄岩具有介于地幔橄榄岩和堆晶岩之间的某些过渡特征。

Neoproterozoic Baoxing Complex in middle to lower metamorphic grade, located in western margin of Yangtze Craton, consists mainly of metamorphic gabbroic, dioritic gneisses, tonalitic and granodioritic gneisses, and massive monzogranites The studies of petrochemistry and SmNd isotopes of Baoxing Complex reveal that the gabbroic and dioritic magmas came from a congenetic magma derived from the partial melting of spinel lherzolites in depletive mantle, and that the magma was intensively contaminated by crustal materials during its emplacement The tonalitic and granodioritic magma were derived from the partial melting of metamorphic basalts in the lower crust And the monzogranitic magma was formed from partial melting of metagreywacks Integrating the lithological association, their trace elements, SmNd isotopic characteristics and petrogenesis, the Baoxing Complex must likely have been emplaced in an island arc tectonic background at the Neoproterozoic active continental margin of Yangtze Craton
位于扬子克拉通西缘的新元古代宝兴杂岩主要由中低级变质的辉长质片麻岩、闪长质片麻岩、英云闪长质到花岗闪长质片麻岩和块状二长花岗岩组成。岩石地球化学和SmNd同位素特征表明，辉长质片麻岩和闪长质片麻岩为同源岩浆演化序列，原始岩浆起源于亏损地幔尖晶石橄榄岩的部分熔融，在上升和侵位过程中受到了地壳岩石强烈混染。英云闪长质和花岗闪长质岩浆形成于下地壳玄武质岩石部分熔融，而二长花岗质岩浆形成于杂砂岩的部分熔融。综合分析宝兴杂岩的岩石组合、微量元素和同位素特征，该杂岩体最有可能形成于新元古代活动大陆边缘火山弧构造背景，并可能经历了碰撞过程。
-
From the above, the authors conclude that the Pl-lherzolite is the product of the reequilibrium between the depleted harzburgite and the basic melt.
笔者认为，含长二辉橄榄岩为基性熔体渗入到先前已亏损的斜辉辉橄岩中，并与之重新平衡的产物。
-
The main lithofacies feature of East Part rockbody contains large plagioclase,while there locally exists little(or doesn\'t exist) plagioclase-bearing lherzolite in the West Part rockbody.
东段岩体以出现大量的含斜长石岩相为主要特征，西段岩体以不出现或只局部出现斜长二辉橄榄岩异离体与东段岩体相区别。
-
The Pl-lherzolite differs from the cumulates in having blastic texture and high-temperature deformed fabric of Ng[100] characteristic of the mantle peridotite and yielding orthopyroxene.
含长二辉橄榄岩以其具有地幔橄榄岩特有的变晶结构和Ng(100)高温变形组构，以及含斜方辉石等特点而区别于堆晶岩。
-
The deep-seated xenoliths entrained by the Cenozoic Hannuoba basalts can be divided into three groups according to their mineral assemblages:Ⅰ Granulites, including felsic granulites, noritic granulites, and dominantly, two-pyroxene granulites,Ⅱ Pyroxenites, including websterites, spinel pyroxenites, and garnet pyroxenites;Ⅲ Peridotites, including spinel lherzolites and spinelgarnet lherzolites.
