Chemical composition of <0.001 mm grain size fractions of bottom sediments and cementing mass of basalt breccia from the North Atlantic

A comprehensive study of 102 samples of grain size fractions 0.010-0.005; 0.005-0.001, and <0.001 mm showns that clay mineral compositions from bottom sediments of the Faroe-Iceland Threshold and Faroe-Shetland Trench are different. In the first case it is essentially smectite-chlorite, in the se...

Description
Summary:A comprehensive study of 102 samples of grain size fractions 0.010-0.005; 0.005-0.001, and <0.001 mm showns that clay mineral compositions from bottom sediments of the Faroe-Iceland Threshold and Faroe-Shetland Trench are different. In the first case it is essentially smectite-chlorite, in the second - mainly hydromicaceous. The difference in composition of clay minerals is due to influence of different source areas of terrigenous material.
