Abstract. Pelites (shales and mudstones) are arguably the most important rock type for interpreting metamorphism. Their significance derives from their widespread occurrence and the range of mineral assemblages they develop at different conditions of pressure and temperature. We compiled a global database of 5729 majorelement wholerock ...

A novel process was developed for the preparation of ultrafine silica from potash feldspar. In the first step, potash feldspar was roasted with Na2CO3 and was followed by leaching using NaOH solution to increase the levels of potassium, sodium, and aluminum in the solid residue. The leaching solution was then carbonated to yield ultrafine silica. The optimized reaction conditions in the ...

Recently, Jena et al. [ 97, 101] reported the use of industrial wastes like lime mud and marble sludge powder, as an excellent additive for potash recovery from mica scrap. Almost 9399% potassium could be recovered from the mica scrap at 950 °C using a ratio of mica, lime mud/marble powder and NaCl at 1::

Increasing Kfeldspar content in sandstones can significantly affect the permeability for the given porosity at certain time, and. As the orientation of Kfeldspar grains aligns parallel to the fluidflow direction, this plays an important role in the evolution of fluidpath inside the sandstone, hence improving permeability for a given porosity.

Recrystallized Kfeldspar that grew within the reaction matrix of the ultramylonite appears to vary slightly geochemically in terms of composition and accounts for the modal enrichment of Kfeldspar compared to the protogranodiorite. Biotite grains recrystallized with progressive deformation and show an expected Ti decrease (Table 3 and Fig. 6F).

Modified date: 23/04/2023. Feldspar is the name of a large organization of rockforming silicate minerals that make up over 50% of Earth's crust. They are discovered in igneous, metamorphic, and sedimentary rocks in all components of the sector. Feldspar minerals have very comparable structures, chemical compositions, and bodily properties.

The quartz:Kfeldspar ratios ranged from to (Table 1), except for sample RC1 (ratio of 31). RC1 had an exceptionally high quartz:Kfeldspar ratio due to its large concentration of quartz (85%) (Table 1). Similar quartz:Kfeldspar ratios were observed for the DJP loess and the deserts to the north and west of the CLP (Figure 3).

Feldspar (sometimes spelled felspar) is a group of rockforming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. [3] The most common members of the feldspar group are the plagioclase (sodiumcalcium) feldspars and the alkali (potassiumsodium) feldspars. [4]
