Rapid Weathering of a Trioctahedral Mica by the Roots of Ryegrass

Soil Science Society of America Journal, 1992
Abstract The weathering of a trioctahedral mica (phlogopite, 2–100‐µm particle size) was investigated in the rhizosphere of ‘Turilo’ Italian ryegrass ( Lolium multiflorum Lam.).

Compositions of trioctahedral micas in the Cornubian batholith

Mineralogical Magazine, 1988
AbstractNew major and trace element chemical analyses of trioctahedral micas of the Cornubian batholith emphasize their enrichment in a ‘trace-alkali element’ association (Li, Rb, Cs, F, Nb, Mn) and their deficiency in a ‘femic element’ association (Zr, Ce, Th as well as Mg and Ti) compared with micas from many other granite suites, although there are ...

Eu(III) coprecipitation with the trioctahedral clay mineral, hectorite

Clays and Clay Minerals, 2006
AbstractVarious secondary phases formed during alteration/dissolution of HLW (high-level nuclear waste) borosilicate glass represent a significant retention potential for radionuclides including divalent actinides. The trioctahedral smectite, hectorite, Na0.7[Li0.7Mg5.3Si8O20(OH)4], is one of the secondary phases identified within the alteration layer ...

Dielectric properties of iron-bearing trioctahedral phyllosilicates

Physics and Chemistry of Minerals, 1997
Measurements of the real part of conductivity (σ′) and dielectric function (ɛ′) were performed on large crystal flakes of biotite (Moen) and vermiculite (Benahavis), at variable frequencies (0.1 to 1000 kHz) and as a function of temperature (300 ...

Interstratification of trioctahedral and dioctahedral smectites through delamination and costacking

Journal of Colloid and Interface Science, 2008
Trioctahedral and dioctahedral organosmectites delaminate in 1-octanol to give stable monolayer colloidal dispersions. Addition of acetone to a mixture of these colloidal dispersions yields a composite of the two clays. Layers of the two smectites are interstratified in the composite.

Rational design and synthesis of excavated trioctahedral Au nanocrystals

Nanoscale, 2015
Excavated polyhedral nanostructures, possessing the features of high surface area and well-defined surface structure with a specific crystal facet and avoidance of aggregation, could be one of the best choices for the purpose of reducing consumption and improving performance of noble metals in many application fields.

Thermal and spectroscopic analysis of natural trioctahedral chlorites

Journal of Thermal Analysis, 1991
A set of seven natural trioctahedral chlorites have been studied. Thermogravimetric techniques and infrared spectroscopy were used to determine the thermal dehydroxylation of the samples. Relationships between the compositions of the chlorites and their thermograms were established. A kinetic analysis was also undertaken.

Interpretation of the composition of trioctahedral micas

Professional Paper, 1960
Structural formulas calculated for more than 200 published analyses of phlogopites, biotites, siderophyllites, and lepidomelanes indicate that the additional positive charges carried by trivalent cations proxying for bivalent Mg in the octahedral group of trioctahedral micas are accommodated in two different ways, (1) by a positive charge on the ...

Salt Displacement of Acid‐Treated Trioctahedral Vermiculites

Soil Science Society of America Journal, 1967
Abstract Freshly prepared and 30‐day‐aged samples of HCl‐treated trioctahedral vermiculites from Libby, Montana (L) and northeastern Transvaal, South Africa (S) were leached with 1 N or more dilute solutions of NaCl, KCl, CaCl 2 , or ...
