造山带的前沿科学问题之一是如何实现其向陆内的大规模水平生长。在造山过程中，前陆褶皱-逆冲带会以前展式、后展式或者混合式等形式扩展，形成包含双重逆冲构造和逆冲叠瓦扇等典型构造样式在内的薄皮或厚皮逆冲推覆构造。前陆盆地也会逐渐卷入变形，并发生向稳定克拉通方向的迁移。前陆褶皱-逆冲带的扩展配合前陆盆地的迁移，这样的前陆系统活动形成了造山带大规模的水平生长。
喜马拉雅山是地球上海拔最高的山脉、与青藏高原一起组成了世界第三极，促成了亚洲季风环流，使处于副热带高气压带的本应干旱贫瘠的我国东南沿海变成了湿润富饶的江南。喜马拉雅山的隆升过程一直是地球系统科学研究的国际前沿，那么如此宏伟的山脉究竟是何时、如何开始隆升的呢？

Many of the attendees of last year’s ISGG2016 conference found it to be deeply meaningful. At this conference, they shared recent developments in the field of geodesy and geodynamics around the confer...
Tectonics and seismicity of the ApulianRidge south of Salento peninsula(Southern Italy)
tectonics seismicity multichannel seismic reflection apulia lithosphere flexsure
2015/9/28
Multichannel reflection seismic data were acquired south of the Salento peninsula, in an area where crustal seismicity has been recorded. Seismic profiles show the presence of small grabens bounded by...

The neotectonics of the islands of Faial, Pico and S. Jorge (Azores) is presented. Preliminary paleoseismology data from trench exposures across three active fault zones (Lomba do Meio, Lagoa do Capit...
Geomorphology of the Gubbio Basin (Central Italy):understanding the active tectonics and earthquake potential
tectonic geomorphology normal fault seismogenic sources Umbria-Marche Apennines-29 April 1984 Gubbio earthquake
2015/9/16
The Gubbio Basin is a 22 km long, 4 km wide depression located within the North-Central Apennines fold-andthrust belt. The basin is bounded to the east by the Gubbio Fault, a W-dipping, normal fault d...
The record of earthquakes in India is patchy prior to 1800 and its improvement is much impeded by its dispersal in a dozen local languages, and several colonial archives. Although geological studies w...
Asymmetry of high-velocity lower crust on the South Atlantic rifted margins and implications for the interplay of magmatism and tectonics in continental breakup
The lower crust seaward - dipping reflector devonian volcanic edge seismic refraction
2015/1/6
High-velocity lower crust (HVLC) and seaward-dipping reflector (SDR) sequences are typical features of volcanic rifted margins. However, the nature and origin of HVLC is under discussion. Here we prov...
3-D thermo-mechanical laboratory modeling of plate-tectonics: modeling scheme, technique and first experiments
3-D thermo-mechanical laboratory modeling plate-tectonics
2014/12/31
We present an experimental apparatus for 3-Dthermo-mechanical analogue modeling of plate tectonic processes such as oceanic and continental subductions, arccontinent or continental collisions.
Tectonics and mechanism of a spreading ridge subduction at the Chile Triple Junction based on new marine geophysical data
Chile Ridge Chile Triple Junction Chile Trench Outer Gravity High slab-pull
2017/4/11
The Chile Triple Junction (CTJ), an RTT-type triple junction located at 46°13′ S, 75°48′ W off the western coast of
Chile, is characterized by the subducting Chile Ridge, which is the constructive pl...
A new combined understanding of plate tectonics, Earth internal structure, and the role of impulse in deformation of the Earth's crust is presented. Plate accelerations and decelerations have been rev...
The Role of Crustal Fluids in Strike-slip Tectonics: New Insights from Magnetotelluric Studies
crustal fluids magnetotelluric strike-slip tectonics transform plate boundaries crustal deformation
2009/7/8
The presence of fluids in the Earth's crust can dramatically change the rheology and may control a wide range of tectonic processes, especially in regions characterized by strike-slip deformation. Flu...
