chlo·rite 1

 (klôr′īt′)
n.
A generally green or black secondary mineral, (Mg,Fe,Al)6(Si,Al)4O10(OH)8, often formed by metamorphic alteration of primary dark rock minerals, that appears as a spot of green and resembles mica.

[Latin chlōrītis, a green precious stone, from Greek khlōrītis, from khlōros, green; see ghel- in Indo-European roots.]

chlo·rit′ic (klôr-ĭt′ĭk) adj.

chlo·rite 2

 (klôr′īt′)
n.
The anionic univalent ClO2 group derived from chlorous acid, or a compound containing this group.

The mineral suspension (either chlorite or hematite) was prepared by adding 3.0 g of minerals to 40 ml of distilled water.
One of the explanations for the rapid development of reducing conditions with increasing depth is that [O.sub.2] in the recharge water is consumed due to interactions with redox-buffering minerals (e.g., pyrite and chlorite) present as coatings on the aquifer matrix and solid organic matter (SOM) [2, 3].
The rocks comprise plagioclase, perthite, quartz, and small amounts of biotite, opaque oxide, titanite, rare allanite, and secondary chlorite (after biotite), leucoxene and epidote.
FESEM photographs showed that kaolinite in Chang 7 reservoir often filled in the porosity with booklet shapes (as shown in Figure 1a); chlorite was usually distributed on the surfaces of particles with leaf shapes (Figure 1b) and the form of the illite and the illitesmectite mixed layer were flocculent structure (Figure 1c and Figure 1d).
The minerals identified in the clay fractions of all profiles are as follows: (i) chlorite, (ii) illite or interlayer-cation-deficient mica (Rieder et al., 1998), (iii) smectite and / or mixed-layer smectitic minerals with a high [greater than or equal to] 50 % amount of expandable layers, (iv) mixed-layer minerals with a small amount of expandable layers, (v) kaolinite, and (vi) quartz.
Experimental evidence that such a mechanism could govern a chemical system didn't emerge until 1990, when Patrick De Kepper and his co-workers at the University of Bordeaux in France produced a stationary pattern of spots in a thin gel continuously fed a fresh solution - containing malonic acid and chlorite and iodide ions-in a special chemical reactor (SN: 8/11/90, p.88).
Purpose: This quantitative study aimed to assess the efficacy of sodium chlorite plus zinc gluconate (SC+ZG) mouthrinse in adults with halitosis.
The IR spectra ranging from 3664 to 3406 [cm.sup.-1] are shown in Figure 2, and Table 3 shows comparisons with some chlorite minerals reported in the literature in order to assist with the assignment of the observed bands for chlorite spectra.
Five types of single mineral were used in the experiments, which were quartz, smectite, kaolinite, illite, and chlorite (Figure 2).
Smectite, illite, and chlorite mainly form under alkaline conditions, and kaolinite mainly forms under acidic conditions [23].
The discoveries include a stamp believed to date back from the Assyrian Empire, clay and chlorite stone vessels, bronze arrows, axes, gold and bronze bracelets and necklaces from the iron age.
