The preparation method of XPS test samples was listed as follows: the chlorite
was ground to -2 [micro]m in agate mortar for several hours; then, the samples were put into the distilled water at 25[degrees]C, and the pH value was adjusted to 10 with the addition of chlorite
and reagents; the solution was stirred in flotation cell for 10 min; afterwards, when solution was stewing for 3 min and the mineral adsorption became equilibrium, the pulp was filtrated and the pulp cake was washed with distilled water at pH 10 for three times; the test samples were obtained after the filtrated cake was dried at a low temperature (60[degrees]C).
In addition, dissolved [O.sub.2] could potentially be consumed by reactions with reduced mineral phases (e.g., pyrite, chlorite
, or biotite) and SOM, further contributing to [O.sub.2]-depleted conditions near the ground surface.
Some of the latter contain plagioclase phenocrysts nearly totallysaussuritized (epidote + white mica), with or without altered mafic minerals including biotite, in an altered groundmass of cloudy/saussuritized plagioclase, amphibole, chlorite
, biotite, ilmenite, +/- titanite/leucoxene, calcite (abundant in a few), quartz, and rare serpentine, chalcedony(?) and devitrified glass.
The formation of chlorite
membrane was suitable for the reservoir (Ehrenberg, 1993; Hurst & Nadeau, 1995; He, 2010): (1) Chlorite
membrane could increase the mechanical strength of rock and resist the compaction to some extent, thus making the primary intergranular pore unable diminish further by compaction.
Mixed-layer clays with minor proportions of smectite or vermiculite layers are recognized by the asymmetries of the 10.0 [Angstrom] illite and 14 [Angstrom] chlorite
peaks on XRD patterns of Mg saturated and heated samples respectively and suggest the presence of random mixed layer structures (Figs.
samples with various Fe-Mg substitutions were studied to establish a correlation between the fundamental vibrations ([v.sub.(AlAl)O-OH], [v.sub.(SiAl)O-OH], [[delta].sub.(AlAl)O-OH], and [[delta].sub.(SiAl)O-OH]) and combination bands ([(v + [delta]).sub.(AlAl)O-OH] and [(v + [delta]).sub.(SiAl)O-OH]) of structural OH groups in chlorite
The corrosion rates of illite and chlorite
were 1.9% and 1.6%, respectively.
The paragenetic sequence includes compaction, early carbonate cementation, chlorite
film, illite-smectite mixed-layer clays, feldspar dissolution, precipitation of kaolinite and quartz, montmorillonite illitization, and weak carbonate cementation .
The Ah horizon contains kaolinite and illite, and corrensite appears at the expense of chlorite
. This supports one of the theories saying that corrensite originates from degradation of chlorite
(Briggati and Poppi, 1984).
Poona, for 10 minutes in water, 100 ppm of chlorine, acidified calcium sulfate (1.2% Safe2OACS 50), 1000 ppm of acidified sodium chlorite
(Sanova[TM]), 80 ppm of peroxyacetic acid (Tsunami[R]) and a combination of ACS and Tsunami.
An analysis of eighteen different commercial brands of packaged drinking water purchased from local markets in Mumbai revealed presence of bromate, chlorite
and chlorate in them.
