... The oxidation of pyrite in marine clays exposed to a subaerial environment was confirmed and was determined to be well correlated with decreased adsorption of zinc by the clays. The production of sulfuric acid and iron oxide by this oxidation and the accompanying decrease in pH was demonstrated...

.... In this research the effects of three such materials on depositional characteristics, microstructure, and some index properties of laboratory prepared marine clays were studied. The contaminants used were fly ash, activated sewage sludge, and fuel oil. The clay samples were kaolinite, illite, and a mixture called...

... There are deposits of fine clays on coastal areas in India. Those soils are soft, highly saturated, of low density, and low shear strength, sensitive, and normally consolidated. Such soils are generally termed as marine clays. Reliable undisturbed sampling of desired size in marine clays...

... Consolidation tests on a soft marine clay formation indicated that it was normally consolidated when the tests were performed on cores obtained with a 2-in.-diameter (54-mm) tube sampler and overconsolidated by 0.16 tons/ft 2 (kg/cm 2 ) when the tests were performed on cores obtained with a 5...
