Numerical values in mean grain size, sorting and size fraction columns are in phi units. Sorting The generally poor sorting in these cores does not agree with the moderate to good sorting cited by Kuenen (1964a, p. 10) as typifying deep-sea sands. The disparity probably is caused by excessive amounts of lutite in the trench core sediments. Inorganic constituents Beside clay minerals, the most abundant component, trench sediments contain angular quartz, mica, feldspar and pyrite. These are all cited (Kuenen, 1964) as existing in turbidites. These materials are not diagnostic of their depth of original Marine Geol, 5 (1967) 141-154.
