Surface area and layer charge of smectite from CEC and EGME/H2O
retention measurements – J. Środoń, and D. McCarty
Figure 1b–d. Figure 1. TGA-MS curves for representative Ca-smectites:
(a) Wyoming montmorillonite, (b) Garfield nontronite, (c) Otay
montmorillonite, (d) Ballarat saponite. Black curve = weight loss, gray
curve = relative intensity of mass 18 spectrum. Weight changes from start
to 110 °C, start to 200 °C, 200 °C for 20 h, and from 200 °C at 20 h to 900
°C at 1 h are shown
Figure 3. Amount of H2O released at 200 °C (WBW)
compared to (a) layer charge, Q, per formula unit, (b) tetrahedral
charge per formula unit.
Figure 4. Amount of H2O released above 200 °C, after 20 h of
isothermal heating (TBW) compared to layer charge, Q, per
formula unit.
Figure 6. H2O coverage compared with CECcorr/TSSANr
ratio. The regression is used to refine the TSSANr
calculation (Table 7, column 9).
Figure 7. EGME coverage compared with CECcorr/TSSANr
ratio. The regression is used to refine the TSSANr
calculation (Table 8, column 9).
Figure 8. Relationship between WBW/TSSAEXCH
ratio and Qs (approximated by Q from Table 1). The
regression is used in combination with equation 11 to calculate Qs
and TSSAEXCH from WBW and CEC (Table 9,
columns 7 and 9).
Table 2. Peak position data (in Å) from oriented XRD preparations of
glycolated and air-dry (47%RH) <0.2 mm fractions of studied smectites. The
glycolated samples demonstrate the lack of mixed-layering by the integral
series of 00l reflections, and the air-dry samples – the nature of water
complex (see text for details). Trace mineral contaminants are also listed.

Pyroxene weathering to smectite: conventional and cryo-field
emission scanning electron microscopy, Koua Bocca ultramafic complex, Ivory
Coast – M. Velbel and W.W. Barker
Figure A1. Anaglyph of field of view in Figure 8, showing
denticulated remnant with attached 'cornflake-textured smectite. Air-dried
sample. UW-M LEO FEG-SEM at 2.0 kV.
Figure A2. Anaglyph (at slightly lower magnification) of field of
view in Figure 9, showing smectite microboxwork separated from denticulated
pyroxene by large pore spaces. Air-dried sample. UW-M LEO FEG-SEM at 2.0
kV.
Figure A3. Anaglyph (at slightly lower magnification) of field of
view in Figure 10 showing smectite microboxwork with imbricated arrays of
face-to-fce oriented layers with little interlamellar porosity. Air-dried
sample. UW-M LEO FEG-SEM at 3.0 kV.
Figure A4. Anaglyph of Figure 14, showing biofilm covering
denticulated pyroxene. Note the detailed preservation of the texture of
biofilm (microbial community and extracellular polysaccharides). HPF/freeze-etched
sample. UW-M Hitachi S900 FEG-SEM at 1.5 kV.
Figure A5. Anaglyph of Figure 19, showing denticulated pyroxene with
spongy, void-filling, porous smectite. Note the ‘tube’ of partially
detached wavy smectite on a denticle in the lower left. HPF/freeze-etched
sample. UW-M Hitachi S900 FEG-SEM at 1.5 kV.
