... fluids. Critically, within the imposed reverse compressional stress regime, hydrothermal fluids were forced to attain supralithostatic pressures, and the resultant V 2 / V 2 ′ O B vein network forms the main stage of gold mineralization. The local abundance of all vein sets is controlled by rheological...

.... Eastern Tibet is divided into different blocks by a series of nearly east–west- or NW-striking lithospheric faults featuring sinistral strike-slip. Increasing evidence suggests that these fault zones experienced nearly north–south compressional deformation before the mid-Miocene. Along the ASRR fault...

... of lunar lava tubes under compressional stress. This study aimed to understand the morphological deformation in the Gruithuisen region’s lava tube when subjected to compressional stress. A combination of numerical simulations and morphometric analysis was employed to achieve this objective...

... sinusoidal function over a 180° or 2θ domain (Fig.  3 ). Figure 3. Results. The horizontal axis is the interstation azimuth, and the vertical axis is the percentage velocity change between when the Earth is dilatational and compressional due to solid‐earth tides. The blue circles are the results...

... ; Helffrich and Thompson, 2010 ; Rychert and Harmon, 2016 ), the RF traces are assumed to be relatively noise‐free, permitting robust estimation of the crustal structure, that is, crustal thickness ( H ) and P‐to‐S (compressional‐to‐shear) velocity ratio ( V P / V S , or κ ). In practice...

... ) reveals a compressional anisotropy with the structure being ~10% less compressible along the c -axis than along the a -axis ( Table 1 ), following a pattern of anisotropy similar to that of pezzottaite but different from that of beryl or cordierite ( Miletich et al. 2014a , 2014b ; Scheidl et al. 2014...

... in a multi-anvil apparatus using a synchrotron-based ultrasonic technique. Our results show that the glass compressed isothermally at 300 K (cold-compression) displays anomalously decreasing compressional (V P ) and shear (V S ) wave velocities with increasing pressure until ~8 GPa. Beyond 8 GPa, both V P...

.... ( a ) Plot of the pressure dependence of the vibrational mode frequencies of the 3.65 Å phase in the hydroxyl stretching region. Deconvoluted mode frequencies from five compressional runs using two different PTM. The pressure dependence of the modes is adequately described by a polynomial expression shown...

... rising sea level. The deposition of areally extensive sediments increases both seal area and deposition of source. The Zagros fold belt is a significant exception to most supergiants. The Zagros is a geologically young, detached compressional fold belt without a sag event with exceptionally large folds...

...Thomas N. Lamont; Andrew J. Smye; Nick M.W. Roberts; Michael P. Searle; David J. Waters; Richard W. White Abstract Metamorphic core complexes are classically interpreted to have formed during crustal extension, although many also occur in compressional environments. New U–(Th)–Pb allanite...
