Partly melted rocks under Earth’s surface offer insights into what makes plate tectonics possible（图）
地球表面 板块构造 构造地质学
2023/6/26
Using seismic waves, scientists detect widespread partially molten rock hidden under the Earth’s tectonic plates in a new way, a step in settling a long-held geological debate that has big implication...
新生代以来的板块汇聚对欧亚古地理格局以及全球气候产生了深远的影响。这一过程主要受控于印度、阿拉伯、非洲板块与欧亚大陆的汇聚，板块的汇聚不仅导致了新特提斯海的向西关闭，也导致了特提斯构造域的造山带隆升、东亚季风的加强以及亚洲内陆中纬度的干旱化。对印度与欧亚板块碰撞的时间、过程、气候效应等方面已经有很多的研究，但是对西亚地区阿拉伯板块与亚洲板块的碰撞时间的争议较大，存在晚白垩、晚始新世-早渐新世、早中...
已知造山带的垮塌多发生在造山期后，王二七及其合作者开展的构造和沉积研究揭示，位于青藏高原东南缘的红河-哀牢山断裂带的伸展垮塌发生在造山主幕。
造山带是板块构造中最为活跃的单元。通常，一条造山带新生于刚性板块间的汇聚和挤压作用之下，在板块碰撞拼合之后，由于其身处板块内部，会因为风化剥蚀作用逐渐地销声匿迹。几千万或几亿年之后，在外部新的板缘构造体系的驱动下，这条古老的造山带会再次活动，形成高耸的山脉，称为重生。造山带的“新生与重生”是地球演化历史中的普遍现象，然而驱使造山带“旋回式”演化的动力如何持续与继承是当前地球动力学研究的争议性问题。...
Earth has some special features that set it apart from its close cousins in the solar system, including large oceans of liquid water and a rich atmosphere with just the right ingredients to support li...
South Scandinavian joints and Alpine/Atlantic-ridge tectonics

Field observations and studies of the joints and dykes in an area shed light on its younger tectonic development; thus, joint orientations measured in Southern Sweden and in Norway have been statistic...
Active faulting and transpression tectonics along the plate boundary in North Africa
Tell Atlas North Africa Plate boundary Transpression
2015/8/26
We present a synthesis of the active tectonics of the northern Atlas Mountains, and suggest a kinematic model of transpression and block rotation that illustrates the mechanics of this section of the ...
Characterising the origin, nature and fate of sediment exported from catchments perturbed by active tectonics
Characterising the origin, nature fate of sediment exported from catchments perturbed active tectonics
2014/5/20
Changes to the tectonic boundary conditions governing erosional dynamics in upland catchments have a significant effect on the nature and magnitude of sediment supply to neighbouring basins. While the...
Tectonic Evolution of the Kiraz Basin, Küçük Menderes Graben: Evidence for Compression/Uplift-related Basin Formation Overprinted by Extensional Tectonics in West Anatolia
Küç ük Menderes Graben Kiraz Basin syn-compressional sedimentation extensional tectonics W Anatolia
2009/7/7
The Kiraz Basin which is located at the eastern end of the Küçük Menderes Graben was previously considered to be an extensional basin. However, the data presented here allow us to infer that th...
Yo-yo Tectonics of the Niğde Massif During Wrenching in Central Anatolia
apatite fission track exhumation Niğ de Massif wrench zones yo-yo tectonics
2009/7/7
Yo-yo tectonics occurs in wrench zones in response to switches between transpression and transtension or to changes in the geometries of faults during these modes of deformation, and involves multiple...
