| 1. | Sedimentary - tectonic event and hyhrothermal depositional mineralization in palaeozoic sedimentary basin , south qinling 构造事件与热水沉积成矿 |
| 2. | A tectonic event may have diverted the system ' s sources toward the ganges plain , though there is some uncertainty about the date of this event 尽管这条河流的修建日子无法确定,但修建的结果也许是把水源引入恒河平原。 |
| 3. | The region in which the river ' s waters formerly arose is known to be geologically active , and there is evidence of major tectonic events at the time the indus civilization collapsed 从前被河水淹没的地方现在升起来,被认为是地质运动,但有证据表明这是印度河流域文明倒塌时候的主要建筑。 |
| 4. | 5 . the mesozoic volcanism in yanshan area temporarily and spatially corresponds with the regional tectonic events , which might be a consequence of deep lithospheric processes and multi - plate interaction 5燕山地区岩浆活动与构造事件有较好的偶合关系,其构造岩浆活动可能是板块相互作用和深部岩石圈活动的共同结果。 |
| 5. | 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。 |
| 6. | 4 . the relative fertile lithospheric characters of yanshan area , unique plate tectonic situation and developed deep faults can explain reasons of the volcanism and tectonic events in yanshan area throughout the mesozoic 4燕山地区特有的相对“易熔”的岩石圈性质,所处的特殊的构造位置及发育的深大断裂,可以较好的解释该地区发生贯穿整个中生代的火山活动和构造变形的可能性。 |
| 7. | Several important tectonic events took place in the chinese continent during the early paleozoic , such as the amalgamation of xiyu plate , forming a unified crystalline basement with the cathaysian plate , development of widespread intraplate deformations in southern yangtze plate , and the occurrence of altay - ergun collision zone 它们与苏格兰阿帕拉契亚的加里东事件完全不同,在中国大陆出现了西域板块完成拼合,华夏板块构成统结晶基底,南扬子板块广泛发育板内褶皱,此时还形成了阿尔泰额尔古纳碰撞带等重要构造事件,而以中朝和北扬子板块为代表的其他板块则主要表现为稳定沉积,地块运移,并呈离散状态。 |
| 8. | K - ar age of an illite from alteration rock in the contact zone around lianhuashan porphyry is 38 . 6ma . with referencing to the main metallogenic period of yulong copper metallogenic zone and of ailaoshan gold metallogenic zone , it is suggested that the time of formation of deposits in the district studied is probably in a period of time from 38 . 6ma at earliest to 20ma at latest . this time is equivalent to the origination time of two important tectonic events , i . e . , lanping movement and the turning point when ailaoshan - red river fault turned from sinisteral into dextral 获得了莲花山岩体周围接触带蚀变岩中伊利石k - ar年龄38 . 6ma ,参考玉龙铜矿带和哀牢山金矿带的主要成矿期(分别为30ma左右及26ma ) ,厘定本矿集区成矿年龄下限为38 . 6ma ,上限为20ma ,与两次重要的构造事件?兰坪运动的起始时间及哀牢山?红河断裂由左旋转为右旋的时间相当。 |
| 9. | Ordos basin is known occurring on the stable north china craton , and there are relatively faint tectonic events in the inner of the basin , it is therefore important to make sedimentary facies and sequence stratigraphy research in order to clarify the distribution of reservoirs and explore oil and gas abundance areas 众所周知,鄂尔多斯盆地发育于华北克拉通稳定基底之上,盆地内部构造活动比较微弱,因此,开展盆地沉积相与层序地层学研究,对于搞清储集空间的展布规律、寻找油气的富集区都具有十分重要的作用。 |
