| 5. | Since eclogite and the coexisting high - pressure granulite have been found in western syntaxis , we ' ll ask whether it is possible that eclogite also can occur in eastern syntaxis 西构造结已经发现榴辉岩和与之共生的高压麻粒岩,东构造结是否也可能存在榴辉岩呢 |
| 6. | High - pressure granulite and the coexisting eclogite and coesite - bearing ultrahigh - pressure eclogite have been subsequently found in the western syntaxis since 80s " last century 自20世纪80年代以来,西构造结已经发现了高压麻粒岩,与高压麻粒岩共生的榴辉岩和含柯石英的超高压榴辉岩。 |
| 7. | Lots of information suggest that the metamorphism process of this area are from granulite facies to amphibolite facies and the retrograded metamorphic path is basically a cw nearly isothermal decompressional evolvement trend 各种信息表明本区的变质作用是由麻粒岩相退变到角闪岩相。退变质轨迹基本上是一个顺时针近等温减压型演化趋势。 |
| 8. | Siziwangqi of inner mongolia is located on the north margin of north china craton , the junction of north china craton and siberia . granulite xenoliths are found there in cretaceous basalt . these xenoliths are mainly plagioclase - pyroxenite 内蒙古四子王旗地区地处华北板块北缘,与西伯利亚板块的接合部,其早白垩世橄榄玄武岩中发现大量下地壳麻粒岩捕虏体,并可见辉石长石捕虏晶。 |
| 9. | Based on the studies of petrotexture , structural deformation and the relevant metamorphism , this paper indicates that this peridotite massif is the product of ultramafic magma cumulated at the crust - mantle transtion zone and has undergone the early stage of plastic deformation under the condition of granulite facies ( 800 ) and late ductile shearing at amphibolite and greenschist facies in relevance to uplifting 本文通过岩体的结构、构造变形及相应的变质作用研究,提出了该橄榄岩体是由超基性岩浆在壳幔过渡带结晶而成,并经历了与围岩一致的麻粒岩相( 800 )条件下的早期塑性变形以及角闪岩相和绿片岩相退化变质条件下与逆冲上升有关的韧性剪切变形。 |
| 10. | However geological information is fully recorded in the remote sensing image , which made it possible for the choosing of this area as a dissection point to extract complex structural information of orogenic belt in west china . taking fully advantage of multi - band image richly bearing concealed geological information in combination with remote sensing analysis and structure analysis , to anatomy the supracrustal composition and structure of orogenic belt with the regional linear structures and their partitioned block and schistous geological masses as the macro - frame ( in corresponding to structure units and structure segments ) and with the rock masses , structure - rock assemblages , line - featured and belt - featured structures as well as penetrative and non - penetrative foliation ( primary stratum and trans position layering ) and folds as the texture and structure elements . the methods of how to distinguish granulite > ductile - shear zone , imposed fold , different deformed belts - 因而,本文选择这一地区作为我国西部地区从遥感图像上提取造山带复杂结构构造信息的解剖区,充分利用遥感图像多波段反映物质属性的特点和图像处理提取隐含信息的优势,采用遥感解析?构造解析相结合的研究方法,以区域线状构造及由它划分的块状、片状地质体为宏观骨架(对应于构造解析划分的构造单元、构造均匀区段) ,以地质体中的岩石岩体、构造岩石组合,线状、带状构造,透入性、非透入性面状(原始层理、新生面理)和褶皱等构造作为用于解析的结构构造要素,进行造山带表壳组成和结构构造解析研究。 |
