| 摘 要： | 根据本区地质构造的新资料,提出了区域板块构造模型。研究了从俯冲到加利福尼亚型转换和由后者又到俯冲的古地球动力学环境更替的意义。这种更替发生在对本区最重要的中—新生代历史时期,对区域成矿带整体乃至一些金属矿床的形成具有重要影响。论证了一些地体性质,尤其是俯冲-增生杂岩对矿床形成的重要意义。

| Abstract: | The paper presents regional plate-tectonic models based on the recent data on the region geological structure.It also discusses the significance of paleodynamic environment alterations,from the subduction to transform of Californian type,and vice versa.These are environments that took place in most important period ofMesozoic-Cenozoic regional history and that affected general metallogenic zonality and the formation of ore deposits. The importance of terrane nature for the first place subduction-accretionary assemblages in formation of mineral deposits is proved. |
