| 1. | Tectonic enviroments of magmatism in early paleozoic in the north altyn tagh , china 阿尔金山北缘早古生代岩浆活动的构造环境 |
| 2. | The area was wholly uplifted with caledonian orogeny in the early palaeozoic , and underwent thereafter denudation 早古生代以来,加里东运动使本区全面上升,同时遭受剥蚀。 |
| 3. | This result provides new evidence for studying the crustal evolution of the north china platform in the early paleozoic 这一认识为研究华北地台早古生代地壳演化提供了新思路。 |
| 4. | In the previous studies , the orefield was regarded either as a group of typical skam or as magmatic hydrothermal deposits 本文的重要发现之一,是博白-岑溪断裂带早古生代区域性热水沉积成矿活动。 |
| 5. | On the basis of summarization of metallogenic series arid subseries , the authors have discussed regional metallogeny and evolutionary regularity of metallogenic series in qilian orogenic belt in palaeozoic 在成矿系列、亚系列总结论述基础上,探讨了造山带早古生代区域成矿及成矿系列演化规律。 |
| 6. | There were convergence , collision and shortening in the xiyu , altay ergun , southern yangtze and cathaysian plates , but dispersion and stable sediments in the sino - korean , northern yangtze , qiangtang , gangdise and himalayan plates 绝大多数板块基本上保持孤立和离散的状态,这是早古生代中国大陆各个地块构造演化特征截然不同的主要原因。 |
| 7. | One of the most important discoveries in this study is the regional exhalative sedimentary mineralization along the bobai - chenxi faulted zone in early palaeozoic , based on which , the metallogenic model of diplogenesis is developed for the fozichong orefield 博白-岑溪断裂带在早古生代为一同生断裂系统,在拉张环境下沿断裂带形成了一地堑型断陷盆地。 |
| 8. | The middle cambrian early devonian ( 513 - 397ma ) tectonic stage was characterized by a series of tectonic events with different features , which are completely different from the caledonian event that occurred in the appalachian orogen and in scotland 摘要中国大陆早古生代(中寒武世早泥盆世)构造期以发生系列各具特征、分布局限、准同时的构造事件为特征。 |
| 9. | In the 1 : 250000 regional geological mapping of yumenzhen , the two different characteristics , depth and different styles assemblage ductile deformation was found in pianshishan in yumenzhen area in late paleozoic and mesozoic 在玉门镇幅1 / 250000的区域地质调查中,发现三危山断裂带东段一甘肃省玉门镇片石山一带存在着早古生代和晚古生代两期不同性质、不同层次、不同构造组合样式的韧性变形。 |
| 10. | There are two suture zones in beishan area : the hongliuhe - niujuanzi - xichangjing suture zone ( early paleozoic era ) and the hongshishan - pengboshan suture zone ( upper paleozoic era ) , and the latter is the final plate junction between the tarim plate and kazakhstan plate 认?本区先后存在红柳河牛圈子洗肠井(早古生代)和红石山百合山蓬勃山(晚古生代)两条缝合带,后者是哈萨克斯坦与塔里木板块的最终缝合带。 |
