您要查找的是不是:
- Pengxian copper deposit and the Masongling Formation acting as host formation are products of island arc volcanism in convergent plate boundary. 证据表明,马松岭组及其所赋存的铜矿床均为会聚性板块边界古火山岛弧的产物。
- accreting convergent plate boundary 增生聚敛板块边界
- Orogeny and gravitational collapse along the convergent plate boundary and their mechanical origin: a case study on the Yarlung Tsangpo-Himalaya belt 板块汇聚带的造山和重力垮塌作用及其力学成因:以雅鲁藏布江-喜马拉雅山汇聚带为例
- convergent plate boundary 聚敛板块边界
- The rift valley is a classic example of a divergent plate boundary. 裂谷是一个典型的例子一个不同的板块边界。
- converging plate boundary 会聚板块边界
- Taiwan is located at a part of the convergent boundary between the Eurasian and Philippine Sea plates.A lot of geotectonic problems are have been created by the convergent plates. 由于台湾位在欧亚大陆板块和菲律宾海板块的交界上,受到板块相互间的作用,产生了许多的地体构造。
- The site of this destruction is another kind of plate boundary: a subduction zone. 销毁旧岩石圈的地方形成另外一种板块边界:一块潜没的区域。
- The convergent and divergent velocities of active plate boundaries in the north hemisphere are obtained with space geodetic data. 利用现代空间大地测量技术测出北半球活动板块边缘会聚、扩张和滑动速度。
- They mainly occur in orogenic belts of various geological times and are formed during extension periods against the background of convergent plate margins. 它们主要产于各个时期的造山带中,形成于以会聚板块边界为大背景的局部引张阶段;
- They occur in composite intrusions in and near deep fractures at plate boundary. 外生稀土矿床中最重要的是海滨砂矿。
- This area was in an arc and rear-arc basin on convergent plates in the Middle Devonian. 其岩石化学及地球化学显示岛弧火山岩特征。
- Being the residual island are of the convergent plate subducted to the south, the central Baiyin Minerogenetic Belt is located at the southeast edge of the north Qilian Caledonian eugeosyncline. 该成矿带位于北祁连加里东优地槽的东南缘。 这里是向南俯冲敛合板块残留的岛弧。
- Plate boundaries are often rich in earthquakes and volcanic activity. 板块边界往往出现在在地震和火山过程中。
- A third possibilty is that IVC colapsed primarily due to natural reasons (climate change, tectonic activity along the subduction zone along the Indo-Asian plate boundary) and that there was no Indo-Aryan invasion that took place. 印度河流域文明衰落的第三个可能是由于自然因素(气候改变,伴随着印度雅利安人进入的可建造区域减少),并没有印度雅利安人入侵的发生。
- At the middle scale is the plate boundary level, where the Plate Boundary Observatory (PBO) will image and characterize the slow deformation of the earth along the western U.S. and Alaska. 中级尺度是板块交界,在此,板块交界观测站(PBO)将沿着美国西部与阿拉斯加,拍摄并描绘出地球缓慢变形下的特性。
- The inversion confirms that plate boundary actions are main factors controlling the regional stress field, and spreading forces of mountains and seashores are another important factor. 同时显示了板块在垂直载荷下的弯曲对局部水平应力场造成相当的影响。
- The action of plumes not being confined to plate boundaries is basic to the theory of plate tectonics. 地幔羽的活动并不局限于板块边界,是板块构造理论的基础。
- Certain parts of the plate boundaries along subduction zones appear to be aseismic. 沿消减带的某些板块边界似乎长期无震。
- The rifts therefore represent divergent plate boundaries where seafloor spreading is taking place. 这样,大洋中脊就成为板块分离边界,海底扩张就发生在这里。
