| 1. | Jurassic and cretaceous , the marginal ocean basin was in the stage of ocean crust evolution and had a setting similar to mid - ocean ridge
侏罗白垩纪为洋盆洋壳演化期，处于类似洋中脊的构造环境。 |
| 2. | This suggests that the paleo - ocean represented by qom , separating the south kunlun massif from north kunlun massif , might be a smaller ocean basin other than a bigger one
这说明昆北地块和昆南地块具有相当的亲缘性，分隔它们的其曼于特蛇绿岩所代表的洋盆不大。 |
| 3. | These ophiolites may be originated from the small spreading oceanic ridges of back - arc or inter - arc restricted oceanic basins , and finally emplaced into the deep - sea sediments constituting the ophiolites in orogenic zones
蛇绿岩可能形成于孤后或孤间有限洋盆小扩张脊；最后侵位到深海沉积物中，形成了造山带中的蛇绿岩。 |
| 4. | 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。 |
| 5. | The geochemistry characteristic of fuchsia radiolarian silicalite indicates that they deposited in the of edge of oceanic basin near the continental margin , not the typical caontinental margin environment
从硅质岩的地球化学特征表现来看，紫红色放射虫硅质岩部分不是形成于典型的大陆边缘环境中，而是形成于近大陆边缘的洋盆边缘环境。 |
| 6. | These intrusive rocks are the products of the closure of the yarlung zangbo and banggonghu - nujiang oceanic basins and may represent three magma - induced thermal disturbance events of plate subduction , collision , and post - collision
它们是雅鲁藏布江洋盆和班公湖-怒江洋盆关闭的产物，主体代表了板块俯冲、碰撞和碰撞后三个时期的岩浆热扰动事件。 |
| 7. | The authors put forward that daba - xiugugabu ophiolite belt originated from an ancient oceanic crust fragment of india continental northern marginal ocean basin , that was approximately synchronous with the formation and evolution period of the neo - tethys ocean
笔者提出该区蛇绿岩来源于印度大陆北缘洋盆的洋壳碎片，这个陆缘洋盆与新特提斯洋主体的形成和演化准同步。 |
| 8. | During subduction northward of neo - tethys oceanic plate , ayla - zhongba micro - continental , the marginal ocean basin and india continental drifted northward all together , the marginal ocean basin was gradually contracted and closed by compressed of india continental
在新特提斯洋板块向北俯冲消减过程中，阿依拉仲巴微陆块、陆缘洋盆和印度大陆一起随着向北漂移，在印度大陆向北挤压作用下洋盆逐渐收缩以致最终闭合。 |
| 9. | This thesis studies each structural layer ' s feature : ( 1 ) structural layer of basement : it is a paleozoic folded basement , whose tectonic deformation and magma intrusion is fiercely , and it is affected by the early hercynian tectonic movement and related to the underthrust and closure ( c1 ) of zhungaer ocean basin and the areal pressing of continents ( c2 - 3 ) ; ( 2 ) structural layer of permian : due to the regional extending and fault depression role in mid - hercynian , it occurred to the combinations of structure and magma in santanghu basin and it ' s periphery area , such as a - granite ' s stock , batholiths and diabase ' s dike . there are many fault depressions possible
按照不同构造层，研究了各构造层的构造特征：基底构造层：受早海西期构造作用的影响，与准噶尔洋盆俯冲闭合、而后陆-陆碰撞的区域挤压构造作用有关，为一构造变形和岩浆侵入活动强烈的古生代褶皱基底。二叠系构造层：受中海西区域性伸展断陷作用的影响，盆地及其周缘地区发育与伸展构造有关的构造-岩浆组合，如呈岩株、岩基状侵位的a型花岗岩以及呈岩墙状侵位的辉绿岩等。 |
| 10. | The marginal ocean basin ' s formation and evolution model may be as follows : early triassic , rift was formed by extension and splitting in india ( gondwana ) continental margin during it was drifting southward ; late triassic , the rift had been joined in the neo - tethys ocean in the east and converted into initial ocean basin , and ayila - zhongba micro - continental was formed in north of the rift
洋盆的演化模式是：早三叠世，随着印度（冈瓦纳）大陆向南漂移，其北部边缘因引张裂解产生裂谷，于晚三叠世向东开口与新特提斯洋主体连通，洋盆初具洋壳性质，北侧形成阿依拉仲巴微陆块。 |
