Rheological model of Earth’s crust (model of third generation)

open access: yesЛитосфера, 2018
Introduction. The ground of the rheological Earth’s crust model with a barrier zone between its upper and middle parts is given. The zone is impermeable to fluids radically changes present-day understanding of the upper part lithosphere structure.

Coupling mechanisms of fracture propagation and proppant transport indeep coalbed methane reservoirs

open access: yesMeitian dizhi yu kantan
Objectives and MethodsDeep coalbed methane (CBM) reservoirs commonly exhibit well-developed beddings, strong mechanical heterogeneity, and high in-situ stress gradients. These characteristics result in pronounced nonlinear fracture propagation and strong

Inclusions in super-deep diamonds [PDF]

open access: yes, 2016
Super-deep diamonds may originate from a depth of between 300 and 800 km, although their precise depth of origin remains uncertain. When growing, they trap other minerals from their surroundings, which remain unaltered in their diamond capsule on their ...

Deep inelastic scattering from quantum fluids [PDF]

open access: yes, 1976
A simple and general argument is given for the deep inelastic behavior of the dynamic structure function of quantum fluids at zero temperature. The resulting high-energy tail is shown to give a reasonable fit to existing neutron data for liquid 4He.Peer ...

The discovery of new deep-sea hydrothermal vent communities in the Southern Ocean and implications for biogeography [PDF]

open access: yes, 2012
Since the first discovery of deep-sea hydrothermal vents along the Galápagos Rift in 1977, numerous vent sites and endemic faunal assemblages have been found along mid-ocean ridges and back-arc basins at low to mid latitudes.
