The development of this belt is related to the inception of the Puerto Rico Trench in the middle to late Cretaceous due to the southerly subduction of the Atlantic plate beneath the Caribbean plate. Eastward movement of the Caribbean plate relative to the North American plate in the late ...
This is probably related to erosion of the Au-barren PPS from its original place of formation with movement downslope to its current deposition site with no evidence of hydromorphic dispersion and enrichment in Au and As from the underlying mineralization. This is supported by textural, ...
However, in subsurface porous media (i.e., alluvial groundwater aquifers) nanoparticle and colloid mobility is more constrained and the movement of nanoparticles is typically predicted using colloid filtration theory (CFT) because of the greater potential for collisions with soil grains (Yao et...
of vectors, facilitating their reproduction and population growth. A dispersal host for ticks is an animal species that aids in the movement or dispersal of tick populations from one location to another. Unlike mosquitoes, ticks cannot travel long distances on their own, so they rely on hosts to...

A 7 km- wide belt of Mesoproterozoic basement with mappable, anastomosing, 0.2-2 km thick, greenschist-facies mylonite zones occurs NW of the F-GLZ. Structural kinematics are typically a top-to-the-NW system containing mafic dikes transposed into the foliation. Low-strain domains contain ...

In order to minimise membrane stresses, two of the applied forces (typically the reaction points) are roller contacts, allowing for horizontal movement. The setup introduces a linearly varying tensile stress on the bottom surface between the two roller supports, with a maximum value below the ...
regime of a NW/W-vergent thrusting with a left-lateral oblique component, that was associated with greenschist to amphibolite facies metamorphism, presumably also of Eocene age (∼50–35 Ma), and that may have been related to the left-lateral movement on the Ailao Shan–Red River Shear ...
