| 1. | Further imbrication, folding and metasomatism of the ultrabasic rocks occurred at this time .
超基性岩的进一步叠瓦作用，褶曲和交代作用发生于这个时期。 |
| 2. | Polarity in metasomatism
交替中的极化性 |
| 3. | Discussion on the lithospheric thinning of the north china craton : delamination ? or thermal erosion and chemical metasomatism
关于华北克拉通燕山期岩石圈减薄的机制与过程的讨论:是拆沉,还是热侵蚀和化学交代 |
| 4. | The tantalite mineralisation at portee appears to be associated with quartz core zones , zones of k - metasomatism and with eluvial concentrations
钽铁矿的矿物性质是由石英核心带、 k长石同化矿带和残积层部分组合而成的。 |
| 5. | The daiqianshan intrusion has the same source with other mafic rocks exposed in southeastern china , which had been experienced metasomatism before emplacement
它与中国东南部出露的其它基性岩同源，但未受到地壳的混染作用。 |
| 6. | The formation of the enriched mantle ( em1 ) is attributed to the strong metasomatism - taking place between subducted yangtze lower crust and nc ( north of china ) ancient lithosphere
2 、火山岩、碱性超基性脉岩和基性脉岩(除少数外)都形成于大陆板内拉张环境。 |
| 7. | The trace element compositions and sr - nd isotopes suggest that the upper mantle beneath the studied area were subjected to multiple episodes of metasomatism , probably by small melt fractions derived from the asthenospheric mantle
微量元素和sr - nd同位素特征表明该区上地幔经历了多期地幔交代作用，交代介质可能是源自软流圈的小体积熔体。 |
| 8. | However , in the area with strong magma mingling , there are widespread abnormal fabrics , distinguished differences in the idiomophic - textures and the peritectic reaction , poililitic texture , metasomatism among the minerals , metasomatic border , embayment , rimmed structure , abnormal plagioclase zoning , relict fabric as well as the acicular apatite are very common
岩石的异常结构构造十分发育，矿物之间自形程度差异显著，常见包晶反应、包含结构、交代边、熔蚀边、交代蚕食的港湾状结构构造及交代缝合线、矿物镶边、斜长石异常环带和矿物残留等，多见指示岩浆混合的标志性矿物针状磷灰石。 |
| 9. | There are distributed a great number of cenozoic basalts and mantle derived xenoliths in north china and south china . for understanding the materials constitutes , evolution , mantle metasomatism , and inhomogeneity of the lower crust and upper mantle , there is a must of doing some research on these host basalts and the xenoliths
华北、华南地区发育大量新生代玄武岩及幔源包体，对其进行研究，有利于进一步深入了解下地壳和上地幔的物质组成、演化、地幔交代和不均一性以及地球物理反演结果的可靠性等。 |
| 10. | The fluids upwelled to seafloor along fault thus ore - forming metals accumulated . 2 . this paper indicated the definition the hydrothermal sedimentary rocks . the definition is a group of especial sedimentary rocks forming at the temperature ranging from 70 ? to 350 ? ( or more high ) through sedimentation and synsedimentary metasomatism in the seafloor
区内的热水沉积岩主要有硅质岩、钠钾长石岩、重晶石岩、透闪石岩、碳酸盐岩、绿泥石岩和铁白云石斑点千枚岩，它们往往与热水沉积矿体紧密伴生。 |
