Both models showed good correlation between the favorability predicted and the presence of crusts in the field, however, the fuzzy model showed higher correlation and highlighted areas not identified by the Boolean model.
Specifics of magma transport through the crust below volcanic fields are debated (Lister and Kerr 1991; Buck 2006; Tait and Taisne 2013), but generally it is thought to move via dyke propagation (Valentine and Hirano 2010).
Moreover, crust formation under natural field conditions is very different from crusting in disturbed soil samples.
Maps c, d show the impact of the radiogenic heat production of the upper crystalline crust on the thermal field.
The aim is to characterize with potential fields the depth structure and physical properties of a complex area, focusing on features of the upper crust where the potential fields can provide a useful insight, as these features appear to be transparent in the images of seismic surveys carried up to date.
When the scale of the deformation is extended to large geologic structures in the crust of the Earth, the field of study is known as geotectonics.
A variation in the stress field of the crust controls the distribution of micro-cracks in the crust, causing seismically observable phenomena, such as variations in seismic wave velocity, scattering of seismic wave and anisotropy of seismic wave velocity.
where B int=−∇V int, B crust is the MF7 crustal field for spherical harmonic degrees 16 to 133, B ext,pomme is the POMME-6 external field, and B ext,correction is the daily external correction, defined as mathbf{B}^{text{ext,correction}}(mathbf{k}) = k(t) left 0.7 hat{mathbf{B}}^{text{ext,dipole}} + 0.3 hat{mathbf{B}}^{text{int,dipole}} right) (8).
Mars's aurora is probably caused by the magnetic field in the crust, rather than the magnetism of the poles as it is in the Earth.
Cameras captured up-close images of Europa's exquisitely cracked crust of ice, and magnetic field measurements indicated that beneath that ice is a layer of electrically conductive material -- what planetary scientists believe is a liquid ocean and possibly the most likely place in the solar system to find life.
