     It proposes for the first time that theformation mechanism of the carbonate rock type stratabound ore deposits of the Sichuan-Yunnan-Guizhou mineralized zone is that the dispersed elements hosted in a beneficial factes-lithologiczone are precipitated and enriched in the course of the late tectonic movement in the presence ofthe leed-zinc remobilization in the enclosed high pressure environment and in the open low pressure environment.

  late tectonic
The Archean Dolodau carbonatite dykes occur near a late tectonic syenite stock located in the Northern Volcanic Zone of the Abitibi greenstone belt.
      
When circulating water was heated by ascending heat flow, gold would be extracted, concentrated and transported from auriferous rocks and then precipitated in the masses during the late tectonic movement.
      
As only one deformation is recorded in the host rocks this suggests that the pluton is late-tectonic.
      


The Wutai group and the equivalent strata in the mountaineous area of Shanxi province underwent recumbent folding during their early evolu tion stage.Their forms and trends,however,are not expressed on the geological maps of the correspond regions,on which the geological boun- daries reflecting the later stage folds with steeper axial planes are pro- minent.

The Wutai group and the equivalent strata in the mountaineous area of Shanxi province underwent recumbent folding during their early evolu tion stage.Their forms and trends,however,are not expressed on the geological maps of the correspond regions,on which the geological boun- daries reflecting the later stage folds with steeper axial planes are pro- minent. Without late tectonic deformation,the features of recumbent fold on the geological map would be the same as those of horizontal strata. That means,with the exception of the hinge zone of the fold,the map would show only a series of geological boundaries parallel to contour ines. If the recumbent fold declined late or the degradation surface were tilted,the map of it would have a series of parallel geological bounda- ries,that is the same as that of monoclinal strata. In case the recumbent fold were superposed by fold with steeper axial plane of late stage,owing to the difference in axial plane between the two phases folds,a complicated pattern would be shown on the map, and it would not be possible to show the feature of the early recumbent fold,therefore the recumbent fold is named as ‘concealed fold’.On the contrary,the recumbent fold with steep axial plane is called as ‘disting- uishing fold’ due to its prominent feature on the map. It is seen here the map of a region underwent superposition folding can only show the'distinguishing foldt of late stage. To realise whether an early recumbent fold exists in a complicated tectonic region of early Precambrian age with a polyphase foldlng-eroding -resedimenting histry,it is necessary to employ the method of spreading oat the folded unconformable surface.

山西各个山区五台群及其相当地层,早期部经历了平卧褶皱作用,而如今地质图上却已看不到早期平卧褶皱的形态与走向,所看到的只是反映后期轴面陡立褶皱的一系列地质界线。平卧褶皱若未经后来构造变动,其图面特征与水平地层区完全一样,除了褶皱转折端以外,只是一系列平行等高线的地质界线。当平卧褶皱后期发生倾斜或剥蚀面是倾斜时,它的图面特征与单斜地层一样(除了转折端以外),将是一系列平行的地质界线。当平卧褶皱受到后期轴面陡峻的褶皱迭加时,随着迭加褶皱轴向与轴面的不同,将出现一系列复杂的图案,早朝平卧褶皱的特征已无法在图面上保存。故我们把平卧褶皱称为“隐性褶皱”,而轴面陡峻的褶皱,因为在地质图上可明显地看出它们的特征而称之为“显性褶皱”。由此可见凡早期是“隐性褶皱”的褶皱区,其地质图只显示后期轴面陡峻的“显性褶皱”。对几经褶皱—剥蚀—再沉积的早前寒武纪复杂构造区,要识别早期是否存在平卧褶皱需通过将已褶皱的不整合面展平的方法才能求得。因为经过变位与变形的平卧褶皱,现在已经以轴面倾向与倾角不等的平厅褶皱面貌出现了。在这些地区由于研究程度及客观保留程度不同,早期平卧褶皱被忽视的可能性是相当大的。

In this paper, the authors describe in detail the process of paleomagnetic study on rocks of Hainan Island and vicinity from Cretaceous to Quaternary. By analysing the data of paleomagnetism, the authors give a tectonic evolutionary model of Hainan Island since Cretaceous; first, southward clockwise, and then northward counterclockwise. Combining the data of Geology with that of Geophysics about the proceeding, particularly about Beibu Gulf (i.e. The Gulf of Tonkin), the authors propose a preliminary idea on...

In this paper, the authors describe in detail the process of paleomagnetic study on rocks of Hainan Island and vicinity from Cretaceous to Quaternary. By analysing the data of paleomagnetism, the authors give a tectonic evolutionary model of Hainan Island since Cretaceous; first, southward clockwise, and then northward counterclockwise. Combining the data of Geology with that of Geophysics about the proceeding, particularly about Beibu Gulf (i.e. The Gulf of Tonkin), the authors propose a preliminary idea on tectonic movement of Hainan Island as follows. In the early stage, there is an extentional process in Beibu Gulf, which makes evidently the crust of Beibu Gulf thin and extends and forms Beibu Gulf Basin, so as to result in the fore tectonic movement of Hainan Island, and the late tectonic movement of Hainan Island as an effect of the opening of the South China Sea. Elucidation of the law of movement of Hainan Terrane has great theoretical and practical significance for study on the formation and evolution of the oil and gas basins in Beibu Gulf.

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。
