“…Armstrong (1957) reports that the clay-sized particles in the glaciomarine clays of the New Westminster area are chiefly quartz and feldspar with clay minerals being present in small amounts or absent. A similar observation was made by Gillott (1979) on sensitive soils from the Vancouver area. Analysis of a marine clay from the KitimatSkeena area indicates a clay mineral content of 75% (40% illite, 35% chlorite), 20% quartz, and 5% feldspar, with minor or trace amounts of montmorillonite or interlayered swelling illitic clays.…”

Landslides in surficial deposits occur commonly in the urban environment of British Columbia. Three groups of surficial materials are especially prone to slope failure. These are glaciomarine sediments, glaciolacustrine deposits, and glacial till that mantles steep mountain slopes. The geological and geotechnical characteristics of these three materials are examined and discussed.The sensitivity, metastable fabric, and geological heterogeneity of glaciomarine sediments control their landslide behaviour. A regional variation in glaciolacustrine deposits is suggested. The Southern Interior and Columbia deposits are dominated by silt varves and those of the Northern Interior by clay varves. The silts are sensitive and collapsible under certain moisture and loading conditions. The effect of urbanisation on these silts in the semiarid Southern Interior is considerable. The retrogressive behaviour of slides in silts and clays in urban areas is also examined.Open-slope and channelled debris flows in till mantles are discussed. They occur mainly on steep slopes in the Coast Ranges as a response to heavy, relief-induced rainfall. The effect of urbanization on slope stability is also discussed.Des glissements de dtp6ts de surface se produisent frkquemment en milieu urbain en Colombie britannique. Trois groupes de matkriaux de surface sont particulikrement sujets B glissement. Ce sont les sediments glacio-marins, les dCp6ts glacio-lacustres et les moraines glaciaires qui recouvrent des pentes rocheuses abruptes. Les caracteristiques geologiques et geotechniques de ces trois materiaux sont examinees et discutkes.La sensibilitk, la structure mCtastable et I'hCterogCnCitC gkologique des sediments glacio-marins contr6lent leur comportement lors de glissements de terrain. Une variation rCgionale des dCp6ts glacio-lacustres est suggCrCe. Les dCp6ts de la Columbia et du sud interieur de la province sont domints par des varves silteuses, ceux du nord-intkrieur par des varves argileuses. Les silts sont sensibles et compressibles dans certaines conditions d'humidite et de charge. L'effet de I'urbanisation sur ces silts dans la region intkrieure sud h climat semi aride est considerable. Le caracthre retrogressif des glissements dans les silts et les argiles en zone urbaine est aussi examine.Les coulees de debris dans les pentes et couloirs dans les couvertures de moraine sont discuties. Elles se produisent surtout dans des pentes abruptes dans les chaines coti6res B la suite de pluies intenses produites par le relief. L'effet de l'urbanisation sur la stabilitk des pentes est aussi discute.[Traduit par la revue]

“…Gillott (1979) has shown that the fabric and mineralogical composition of sensitive soils from Canada, Alaska and Norway are qualitatively similar. He pointed out that they all possess an open fabric, high moisture content and similar index properties (Table 4).…”

“…Clay minerals exhibit strongly marked colloidal properties and other inorganic materials such as silica behave as colloids when sufficiently fine grained. Gillott (1979) suggested that the open fabric may have been retained during very early consolidation because it remained a near equilibrium arrangement.…”

“…Marine glaciogene clays are known from numerous localities throughout the Arctic and former glaciated areas of the Northern hemisphere (Belmonte, 2015;Gillott, 1979;Locat and St-Gelais, 2014;Locat et al, 1984;Ramesh and D'Anglejan, 1995;Roaldset, 1972;Rosenqvist, 1975). Approximately 150 kg of marine clay from the town of Ilulissat, West Greenland, was sampled from a depth interval of 20-100 cm below surface.…”
