New Details Temperature Mobility Earth’s Lower Crust Rocky Mountains
2018/2/1
Everything on the surface of the Earth rests on massive tectonic plates that resemble a jelly sandwich, with two rigid pieces — the upper crust and the upper mantle — enclosing a gooey middle layer of...
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...
Regional Flow in the Lower Crust and Upper Mantle under the Southeastern Tibetan Plateau
Regional Flow Channel Flow Crustal Deformation Deep and Large Suture
2013/3/7
Seismic tomography reveals an “R-shape” regional flow constrained between the depths of 50 to 80 km in the Southeastern Tibetan Plateau (STP) which demonstrates some of the differences revealed by the...
Evidence for postseismic deformation of the lower crust following the 2004 Mw6.0 Parkfield earthquake
postseismic deformation the lower crust following the 2004 Mw6.0 Parkfield earthquake
2014/4/15
Previous studies have shown that postseismic relaxation following the 2004 Mw6.0 Parkfield, CA, earthquake is dominated by afterslip. However, we show that some fraction of the afterslip inferred from...
Sr, Nd and O isotopic characters of quartz syenite in the Weiya magmatic complex from eastern Tianshan in NW China: Melting of the thickened juvenile lower crust
quartz syenite intra-continental subduction Weiya Central Tianshan Northwestern China
2017/8/9
New Sr-Nd-O isotopic data are reported for the early Triassic (early Indosinian) Weiya quartz syenite from eastern Central Tianshan, northwestern China, with the aim of documenting its possible source...
