Kaolinite and other clay minerals in Arctic Ocean sediments
Illite is the dominant clay mineral but the kaolinite/chlorite ratio of nearly 1.0 is twice that reported in North Atlantic and North Pacific sediments. Kaolinite averages 26% and is present throughout the lengths of all cores, some of which penetrate 2.8-3.0 m.y. old sediment.

Kaolinite averages 26% and is present throughout the lengths of all cores, some of which penetrate 2.8-3.0 m.y. old sediment. The widespread accumulations of kaolinite under conditions apparently unfavorable to its formation has special paleoclimatic significance because it has been used as an indicator of low latitude weathering.

01.04.2021According to the exploratory experimental results, when the kaolinite particle size is reduced to 50 μm, the sedimentation equilibrium velocity falls to approximately 1 mm/s. If the particle size continues to shrink, the sedimentation equilibrium velocity value will change in magnitude; therefore the particle size range is set at 50–500 μm.
