ophiolitic melange meaning in English
蛇绿混杂岩
Examples
- There exists a series of meso - neoproterozoic tectonic melanges and ophiolitic melanges in jianping - fuxin - tieling area of northern liaoning province
摘要辽宁北部建平阜新铁岭地区,存在一套中新元古代构造混杂岩系、蛇绿混杂岩。 - The basic to ultra - basic rocks are distributed along suture zones , whereas the intermediate to acidic intrusives occur mainly to the south and north of the arsuo tectonic melange zone and the angren ophiolitic melange zone
基性-超基性岩沿结合带分布,而中酸性侵入岩主要分布在阿索蛇绿混杂岩和昂仁蛇绿混杂岩的南北两侧。 - The geochemical characteristics of gabbros from the jinshajiang ophiolitic melange indicate that they were derived from a mantle source different from that of volcanic rocks , which may be a product in the ocean rift in the earlier stage
东竹林蛇绿混杂岩中辉长岩地球化学特征表明,它与火山岩不同源,可能是洋盆裂谷初期的产物。 - In the light of rock association , origin , age , deformation and metamorphism , disintegration and collage , migration and displacement , the " litang ophiolite group " is redefined as the " litang ophiolitic melange group " , which may be redivided into two formation complexes , i . e . the kar ophiolite formation and waneng ophiolite formation and five types of exotic blocks composed of clastics and marbles
按结合带内岩块的不同组分、不同来源、不同时代、不同变形变质程度的不同,对各类岩块进行四维裂解拼合复原后划分为两个岩组(卡尔蛇绿岩组、瓦能蛇绿岩组)及碎屑岩、大理岩等组成的5类外来岩块。 - Thus , they might be derived from a back - arc basin with an archipelagic system in paleo - tethys , instead of a large ocean basin . the isotopic geochemistry shows that the jinshajiang ophiolitic melange has higher e nd ( t ) values ( + 7 . 42 - + 5 . 44 ) , suggesting that it may be derived from a lree depleted mantle source without significant contamination by the continental crust , but affected slightly by a fluid from a subducted ocean crust
同位素地球化学研究表明,金沙江蛇绿混杂岩具有较高的_ ( nd ) ( t )值( + 7 . 42 + 5 . 44 )暗示蛇绿岩来源于lree长期较亏损的地幔源,演化过程中没有受到陆源物质的明显混染,而主要受到少量俯冲洋壳析出流体的影响。
