Centennial variations in the grain size are associated with a previously described late-Holocene enhancement of the El Niño-Southern Oscillation (ENSO) amplitude, which led to stronger NNE trade winds off eastern Brazil, favouring SW transport of sediments from the Paraiba do Sul River

Paleostress inversion - Wikipedia

Referring to the paleostress inversion principle, rock masses under stress should exhibit strain at both macroscopic and microscopic scale, while the latter is found at the grain boundaries (interface between crystal grains at the magnitude below 10 2 μm) Strain is revealed from the change in grain size, orientation of grains or migration of .
