Upper plate tectonic stress state may influence interseismic coupling on subduction megathrusts
, 2012 We document a correlation between along-strike variation in interseismic coupling depth on subduction interfaces, and the upper plate tectonic stress state in New Zealand, Vanuatu, and southwest Japan.

Dizhen xuebao, 2018 收集了鄂尔多斯地块西缘的21个宁夏区域地震台网台站和183个中国地震科学探测台阵台站记录到的2015年1月至2016年1月期间的远震P波资料，通过对其进行反褶积提取接收函数，并利用H-Kappa叠加方法计算了研究区内的莫霍面深度和泊松比。结果表明：研究区的莫霍面深度在36—58 km范围内变化，大体呈南厚北薄、西厚东薄的特点，且具有明显的分区特征，即以香山—天景山断裂为界，莫霍面在南北向呈现明显的起伏变化，该断裂以南的地壳增厚方式可能与青藏高原的水平挤压力所导致的上地壳重叠有关 ...

Geochemistry and tectonic development of Cenozoic magmatism in the Carpathian–Pannonian region [PDF]
, 2011 This review considers the magmatic processes in the Carpathian–Pannonian Region (CPR) from Early Miocene to Recent times, as well as the contemporaneous magmatism at its southern boundary in the Dinaride and Balkans regions.

Measuring and modelling deformation during the Dabbahu (Afar) rifting episode [PDF]
, 2010 In September 2005, a 60-km-long dyke intruded the Dabbahu segment of the Nubia-Arabia plate boundary (Afar, Ethiopia), marking the beginning of an ongoing rifting episode.

Cenozoic Plate Tectonic Reconstructions and Plate Boundary Processes in the Southwest Pacific [PDF]
, 2005 The Australia-Pacific-Antarctic plate circuit has long been a weak link in global plate reconstruction models for Cenozoic time. The time period spanning chron 20 to chron 7 (43-25 Ma) is particularly problematic for global plate models because seafloor

Minimum stress and pore fluid pressure in sedimentary basins [PDF]
, 2001 Leak-off pressures (LOPs) recorded during leak-off tests (LOTs) conducted down boreholes are often used to estimate the magnitude of the minimum stress (usually assumed to be horizontal – S(_h)) in the subsurface.

Temporal relations between mineral deposits and global tectonic cycles [PDF]
, 2013 Natural Environment Research Council (grant NE/J021822/1) supported this research.Mineral deposits are heterogeneously distributed in both space and time, with variations reflecting tectonic setting, evolving environmental conditions, as in the ...

IOSR Journal of Engineering, 2014 In oil-bearing basins, the relationship between tectonic stress and generation, migration, accumulation of oil and gas has been a research focus in the oil and gas dynamics. This paper takeed the research status of tectonic stress as the foothold, and the research methods of tectonic stress as foundation, summarized the effects of tectonic stress on ...
