| 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。 |

古特提斯洋壳演化的同位素年代学制约 |
| 3. | The ophiolite massifs are composed of mantle peridotite that is mainly harzburgite and dunite , and lacked of crust magmatite within the typical ophiolite suite
摘要该蛇绿岩带的岩体由地幔橄榄岩组成，主要岩石类型是方辉橄榄岩和纯橄榄岩，缺少典型蛇绿岩剖面中的洋壳单元。 |
| 4. | From the study of lead isotope , we know that the lava of erlangping is ocean lava - spilite keratophyre , it is the main origin of lead in time evolvement sequence and genesis
铅同位素研究表明本区二郎坪群的火山岩为洋壳火山岩?细碧角斑岩，在时间演化序列上和成因上它们作为pb的主要源岩。 |

| 6. | Thus while the upper surface of an oceanic plate is a crystalline solid , the underside exhibits a gradual phase change , from solid to plastic to viscous liquid as the temperatures and pressures increase with depth
因此虽然一个洋壳的上部是晶体，下面却显示了逐步的变化，即当温度和压力随深度增加时，便从固体到可塑体再到粘滞的液体。 |
| 7. | The internal mineral separates and whole - rock sm - nd isochron age for gabbro dikes from the dangqiong ophiolite is 373 ? 8ma , inferring a magmatic activity during late devonian , which end ( t ) = + 3 . 3 suggests that its tectonic setting was probably oceanic island
其nd ( t ) = + 3 . 3 ，认为其时形成环境为洋岛，可能代表了新特提斯蛇绿岩形成时所携带的古老洋壳。 |
| 8. | Based on affirming mantle plume hypothesis , the authors introduce several 2d or 3d simulation experiments about ridge - plume ( hotspot ) interaction and some examples of hotspot - ridge interactions existing in the three oceans
研究洋脊热点之间的相互作用对于揭示地幔动力学、热点附近洋壳构造的演变以及与热点密切相关的洋中脊处的岩浆热液活动具有重要的意义。 |
| 9. | 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。 |
