“…Palygorskite is formed after montmorillonite (Plate 4, Figures 5 and 6). A. P. Lisitsen et al (1971) has determined that palygorskite in Cretaceous pelagic clays was formed authigenically in magnesium-rich solutions at Sites 47, 50, and 51, which are east and southeast of Site 436. H. Okada (Okada and Tomita, 1973) also considers palygorskite from Leg 20 sediments to be authigenic.…”

of the Academy of Sciences of the USSR, Vladivostok X-ray DiffractionWe obtained X-ray diffraction patterns of oriented specimens using a DRON-1,5 X-ray diffractometer with CUKQ, emission and a Ni-filter. Slit openings of 0.5, 1,1, and 0.5 mm were used.Each sample was dried in the air, treated with ethylene glycol, and heated at 500 to 550°C for 1 to 2 hours. Clay fractions were treated with 10 per cent HC1 at 90 to 100°C for 1 hour for identification of kaolinite and dioctahedral and trioctahedral minerals. Expanding vermiculite was determined by Mg-ethylene glycol tests. Some samples were K-saturated to test the nature of expanding minerals after Weaver's method (Weaver, 1958). The ratio of 17-Å reflection shoulders (i.e., the Z-coefficient) was calculated. Electron Diffraction Analysis and Electron MicroscopyWe obtained electron diffraction patterns using an electronograph EG-100M with accelerating voltage 100 kv. These patterns were used for determining illite polytypes, the degree of structural ordering of montmorillonite, and the ^-parameter (accuracy ± 0.01 Å). Electron microdiffraction made it possible to recognize acicular crystals and amorphous phases.

“…The results of the mechanical grain-size analyses, utilizing the combined method (Lisitzin et al, 1969), are given in Tables 1-4. Grain-size analyses for fractions of 0.05 to 0.1 mm were also made on the light and heavy fractions obtained by heavy liquid (2.9 g/cm 3 ) separation.…”

“…Sand-silt-clay percentages are routinely determined for all Initial Reports of the Deep Sea Drilling Project, but only Lisitzin et al (1971) for Leg 6 and Boyce (1972) for Leg 11 have performed complete grain-size analyses at 10 unit intervals. However, neither investigator computed statistical parameters of grain-size distribution.…”
