The minerals of the kaolin group comprises kaolinite, dickite
, nacrite, and halloysite with kaolinite being the most common (Murray, 2007).
Frost, RL, "Fourier Transform Raman Spectroscopy of Kaolinite, Dickite
H image encloses the spectral information related to Al-OH bearing mineral assemblages, namely, kaolinite, montmorillonite, dickite
, pyrophilite and clay minerals group.
1989) argue that the FT-IR spectrum as described above could be an indicative of the existence of dickite
and nacrite instead of a disordered kaolinite.
The primary raw material used in this study was a Colombian granulated blast furnace slag (GBFS) from the factory Acerias Paz del Rio, and metakaolin produced in the laboratory by calcination of Colombian kaolin containing minor traces of quartz and dickite
In lithofacies-1 (laterite / bauxite / kaolinite) the goethite, kaolinite, boehmite, gibbsite and dickite
minerals may owe to insitu leaching of older rocks.
Kaolinite, illite, quartz, microcline, dickite
, mordenite, gamma alumina and iron rich minerals, such as pyrite and hematite, constituted the mineral makeup.
Okzhetpes) and reported low-temperature phases such as kaolinite and dickite
, are used to support such an interpretation.
Geologic and alteration mapping have outlined a roughly 2sqkm area featuring typical high sulphidation epithermal systems including silicification and brecciation, alunite, kaolinite and dickite
Analysis revealed that it consisted of kaolinite, dickite
(a closely related clay mineral to kaolinite), nontronite, (a smectite, similar to bentonite, where iron replaces alumina in the crystal lattice), the remainder being quartz.
Fordham GP (1973) Location of iron-55, strontium-85, and iodide-125 sorbed by kaolinite and dickite
Surrounding the vuggy silica alteration is a zone of alunite with minor pyrophyllite and dickite
