1, The Thorium versus Potassium cross-plot confirms illite as being the main clay and kaolinite as the secondary clay mineral.

2, These are: kaolinite, montmorillonite, illite, chlorite and vermiculite.

3, Of these minerals, kaolinite, illite and chlorite are commonest.

4, There are not only illite, but also asphalt, microcrystalline quartz, dolomite, calcite, anorthite, gypsum, and such as potential damage materials.

5, And the ore contains hydromica ( illite ), quartz, organic material and algal fossil.

6, Illite jade, in vein, was discovered in some copper mine, located in Daye county, HubeiProvince, and is a rind hydrothermal alteration rock from anorthosite.

7, Clay fraction is dominated by illite and kaolinite with small proportions of smectite, chlorite and vermiculite.

8, Studies indicates that illite clay deposits of industrial importance tend to be associated with Late Mesozoic sequences in relation to volcanic activities.

9, Transformation of smectite to illite and chlorite is also mainly took place in this stage.

10, Therefore, the illite polytype might be an effective indictor for mineralization of porphyry copper deposit.

11, Kaolinite, halloysite and illite are the major clay minerals in the oxidized zone of Shewushan gold mine.

12, Ore is in the phase of clay minerals in which gibbsite is less and kaolinite commonly coexists with illite.

13, The nodule minerals consist of quartz, plagioclase, amphibole, K ? feldspar , goethite, lepidocrocite, δ MnO ? 2 , illite, and muscovite etc.

14, After surface modica - tion, it is transfered into active illite filler.

15, The hydraulic conductivities of the sand columns containing smectite decrease more obviously than others containing kaoline and illite, whose decreasing extent is about 50% of the former's.

16, The results show that the digestion rate of kaolinite, illite and pyrophyllite in aluminate solution is influenced by reaction conditions such as temperature.

17, Especially in the paper, cosmetics, ceramics three major industries, illite has great application value.

18, The major nonmetallic minerals are quartz, chansthealite, and miner ores are calcite, ankerite. illite hydromica and other clay minerals.

19, The mud was a blue-gray plastic clay composed predominantly of montmorillonite with some illite.

20, The study shows that from the bottom to the top of laterite weathering crust profile, illite and kaolin decrease, gibbsite, goethite and hematite increase.

21, Rock fragments, including volcanics, are common, and the matrix consists largely of kaolin and illite.

22, Influences of phosphates on the dispersion of diaspore, kaolinite , illite and pyrophyllite were systematically investigated by sedimentation experiments.

23, The distinctness of rock for deep clastic gas layers in Songliao basin is laumontitization, sericitization and water-bearing property of illite, and extensive albitization.

24, Although the activation requirements of potassium release are stricter for muscovite, it can release much more potassium than sericite and illite.

25, The Permo-Triassic boundary is put below the bed of illite clay rock (the 34th bed of the Ermen Section, Fig. 1),(http:///illite.html) because ammonoid Lytophiceras sp. is found at the superjacent bed.

26, The results indicate that the jade mainly consists of illite and a small quantity of feldspar, quartz, hematite, siderite and rutile, which is argillaceous sedimentary rock.

27, The high content of fluorine is closely related to the mixed-layer minerals of illite and smectite, apatite, hornblende , and K-feldspar.

28, The scanning electron photomicrograph of aluminosilicate particle shows that the pyrophyllite particles take the shape of thin slice, but illite and kaolinite are particles with irregular appearance.

29, The authigenic minerals include secondary overgrowth quartz, kaolinite and illite before CO2 influx. After CO2 influx, the main cements include dawsonite and ankerite.
