Conclusion the taihua complex in the area is a metamorphic complex undergone low - angle overthrust from the south to the north and uplifting lately by fault blocking , rather than a mcc 结论小秦岭地区的太华杂岩解释为经历了从南向北的铲状逆冲推覆和后期抬升块断剥露的变质杂岩更为合理。
The matching connection between the effective hydrocarbon source rock in jurassic and the other factors of formating - resource in kuche is also influenced by the time of formation of the metamorphic core complex 同时还认为变质核杂岩的形成时期还影响了库车坳陷侏罗系主力烃源岩同其他成藏要素的匹配关系。
Methods a contrast is made between the characteristics of typical mcc and the taihua complex in the xiaoqinling based on investigation and analysis of structural evolution of the xiaoqinling 方法总结前人归纳的变质核杂岩特征，与小秦岭地区发育的太华杂岩特征进行对比，再通过对小秦岭地区燕山期后褶皱、南北两侧发育的断裂进行分析和构造演化史研究。
Partial melting of the enriched lithospheric mantle owing to a raised geotherm caused by lithosphere thinning and following the afc process resulted in the formation of the quannan and tabei syenites in southern jiangxi 随着拉张作用加强，受软流圈物质交代过的岩石圈地幔的小比例部分熔融形成的高钾碱性岩浆经afc作用形成碱性杂岩(全南和塔背岩体) 。
The first stage was characterized by ductile detachment deformations , and during 228ma - 170ma took place high temperature flow deformation and in the period of ivoma - 135ma middle - low temperature deformations occurred , as shown by deformations feature and history of mylonite granites 亚干变质核杂岩的运动学各类构造要素产状协调一致，表明为同期构造产物。其各种宏观、微观运动学标志几乎都表现为上盘对下盘的向sse的剪切运动。
Compared with jianchaling nickel sulflde deposit , jinchuan superlarge copper - nickel sulflde deposit mostly related with mafic - ultramafic complex that multiple intruded , spatially respected with old huabei block , which formed in marginal rift in middle - new proterozoic 与煎茶岭镍矿床相比，金川超大型镍铜硫化物矿床主要与多次侵入的镁铁?超镁铁质杂岩有关，空间上与时代相对较老的华北地块关系密切，形成于中?新元古代的边缘裂谷。
This paper describes distribution characteristics of helium isotopos and some trace elements in different types of rocks along dabie mountain ultrahigh pressure metamorphic complex belt as well as along liuan - caihe geo - science profile , and deals with their affecting factors and geological significance 摘要报导了大别山超高压变质杂岩带不同岩石类型及六安蔡河地学剖面中氦同位素和某些微量元素的分配分布特徵，并讨论了它们的影响因素及其地质意义。
Substance of rock - forming and ore - forming in both jianchaling and jinchuan nickel deposit mainly derived from the upper mantle , but the former source is relatively depleted mantle . on the other hand , there exsisted the crustal contamination during the formation of the two mineral deposits , the later contaminated poorly and gave priority to deep contamination . ( 5 ) by the comparative study of jianchaling with jinchuan nickel sulflde deposit , it is pointed that small basic - ultralbasic complexes which dis ( 5 )通过对煎茶岭和金川镍矿床的比较研究，结合对国内外有关岩浆镍矿床的比较分析，根据我国的地质特点，提出沿较老地块边缘分布的特别是沿华北地块北缘分布的基性?超基性小杂岩体，是找寻大而富的硫化镍矿床之有利找矿方向；而对较老地块内部的镁铁质侵入体，亦应给予高度注意。
Greenschist facies , low green schist facies and brittle shear deformation facies . the attitude of different structural element of the yagan mcc are keeping coordination . analysis of kinematics demonstrates the sse - directed shearing - off of the hanging wall relative to the footwall along the penetrative mylonitic lineation 其变形相由变质核中心到上盘岩系(由深至浅)依次为高角闪岩相? ?绿片岩相? ?低绿片岩相? ?脆性剪切变形相，显示亚干核杂岩由中心向边部变形层次递减的特点。
