Nano-kaoliniteK-feldsparHydrothermal synthesisChemical weatheringKaolinite of paper-coating gradeDevelopment of sustainable routes for the synthesis of kaolinite in nano-scale (nano-kaolinite) is very significant for producing high quality kaolinite of paper-coating grade in kaolin industry. Duplicating ...
The argillic alteration is composed of clay minerals that replace primary aluminosilicate phases, such as K-feldspar and plagioclase. X-ray diffraction (XRD) analysis indicates that kaolinite is the dominant phyllosilicate phase and is generally accompanied by dickite, sericite, quartz, hematite, ...
Therefore, investigating retention mechanisms of LMWOAs in mineral-cation-LMWOAs systems is critical to understanding soil C cycling. Given the general acidic conditions and dominance of kaolinite in tropical soils, we investigated the retention mechanisms of citric acid (CA) in kaolinite-Fe(III)-...
In Fig. 11, only sample Iz12 lies somewhat closer to the kaolinite field. Other Izvir samples plot in the K2O-rich area in the illite or the muscovite fields, some of them even in the pure K-feldspar field, which is not in accordance with predicted intense granite weathering. Further, ...

Core flow testing at 360°F was conducted on outcrops of two types of sandstone representing a heterogeneous (65% quartz and illite/kaolinite with feldspars) and a clean (95% quartz) type of mineralogy. The APCA fluid containing HF acid, which incorporates a modulating agent for the HF ...
The I/S composition of the K-bentonites may be formed by the reaction of smectite with K+ from the pore fluids that bring potassium derived from the break-down of K-bearing micas and K-feldspars (Altaner et al., 1984; McCarty et al., 2009). The altered feldspar closely associated ...
Adularia, a low-temperature K-feldspar, is the dominant mineral formed during K-metasomatic alteration, but mixed-layer I/S, discrete smectite, and kaolinite can also be present in the assemblage. The formation of discrete smectite within the assemblage during K-metasomatism may have occurred ...
