Minimum speed limit for ocean ridge magnetism from (super 210)Pb-(super 226)Ra-(super 230)Th disequilibria
Article Abstract:
A study is conducted to infer that melts of the Earth's mantle can be transported, accumulated and erupted in a few decades using (super 210)Pb-(super 226)Ra-(super 230)Th radioactive disequilibria and other geochemical attributes in oceanic basalts less than 20 years old. The likelihood of magmatic disequilibria occurring before melt enters shallow crustal magma bodies limits differentiation and heat replenishment timescales to decades at the localities studied.

Intense mixing of lower thermocline water of the crest of the Mid-Atlantic Ridge
Article Abstract:
The crest of the Mid-Atlantic Ridge in the subtropical North Atlantic Ocean has indicated that the passages in rift valleys and ridge-flank canyons have provided the most energetic sites for oceanic turbulence. The flux is equivalent to the interior mixing that occurs in the entire North Atlantic basin at the depth of the passages, indicating that turbulence generated in narrow passages on mid-ocean ridges are important for buoyancy flux at the global scale.

Magnetism of the carbon allotropes
Article Abstract:
The diamagnetic and paramagnetic ring currents present in the carbon allotropes, such as fullerenes and C60, considerably affect the magnetism of these molecules. In C60, the sigma-bond anisotropy causes the endohedral chemical shift. The ring currents are responsible for the chemical shift of the surface protons in C60. The study of magnetism shows the presence of pie-electrons moving in three dimensions.
