10 Stuut, 2014). The feldspar minerals can be grouped according to bulk composition into potassium rich feldspar (Kfeldspar) and Na, Carich species (plagioclase). While theseries of plagioclase contains all fractions of Na, Ca, there is a mixing gap for Kfeldspar. Only a limited fraction of K+ can be replaced by Na+ or Ca2+. Kfeldspar is ...

Feldspar Staining. The feldspars comprise a group of aluminosilicate minerals with similar chemical and physical properties. Compositionally, the alkali feldspars (Kfeldspars) form a solid solution from potassium (orthoclase) to sodium (albite) endmembers, whereas the plagioclase feldspars form a solid solution from sodium (albite) to calciumrich (anorthosite) endmembers (Table 3; Deer et ...

However, the application of Kfeldspar IRSL dating has long been hampered by a phenomenon called anomalous fading [16,17,18]. The thermally stable luminescence signal of Kfeldspar fades under ambient temperature, which is suggested to be a result of quantum tunneling between the electron traps and holes [16,17,18,19].

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.

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).

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 ...
