The correlations of δ 41 K with SiO 2 and Al 2 O 3 contents are attributed to the difference in K-O bond strengths. Compared to K-feldspar, the K content could be a better proxy for constraining the δ 41 K of plagioclase. Our results demonstrate that the δ 41 K of K-feldspar is dependent on its mineral chemistry, and its K isotopic ...

K-feldspar is a typical insoluble potassium resource with large reserves and wide distribution. Because there are few sources of soluble potassium in natural resources, extracting potassium from K-feldspar has become a strategic demand in the industry (Su et al., 2015, Ciceri et al., 2017).The K-feldspar is also served as a cosolvent in the glass and ceramic industry due …

Potassium feldspar megacrysts are individual, often zoned, euhedral perthitic crystals within a matrix predominantly made of plagioclase, quartz, biotite, amphibole, and oxides. Megacrysts are a striking component of granitoid plutons, found in numerous exposures world-wide (Johnson and Glazner, 2010, and references therein), with some
K-feldspar, which constitutes about 60 % $%$ of the Earth's crust, is crucial for understanding electrical conductivity in porous rocks.

Potassium-containing feldspars provide a high potential for producing potash, a product with widespread use in agriculture. The present work assesses applying the anti-solvent crystallization method for the purification and recovery of high-purity muriate of potash (KCl) from feldspar leaching solutions. Initially, screening experiments were carried out on a synthetic …
Rubidium typically replaces K in K-feldspar and mica, and can crystallize under a wide range of physicochemical conditions in granitic and pegmatitic systems (Murray and Rogers, 1973, Tischendorf et al., 1997, Černý et al., 2003).Mica and K-feldspar are two of the most important constituent minerals of granites and pegmatites.
K-feldspar is dependent on its mineral chemistry, and its K isotopic composition may be insensitive to other factors, such as the source heterogeneity. The inference is further confirmed by comparing the δ41K values in this study with published δ41K values of K-feldspar from different sources. Keywords: K isotopes, K-feldspar, Al/Si order ...

K-feldspar and plagioclase feldspar. Feldspars have two cleavage planes that intersect at 90°. Fragments of pure feldspar crystals thus tend to form rectangular blocks with irregular ends. Feldspars have vitreous lusters and occur in opaque shades of white to gray to pink to very dark gray. Other rarer colors are also possible!
For the K-feldspar sample, the blue LED treatment reduces even the hardest-to-bleach METx-IRSL signal at 230 °C to a few percent of the initial intensity (shown in these plots at 0.001s for convenience). Each subsequent METx signal is 45 °C above the last, and using blue LEDs (plot a), the bleaching rate at 51 °C is about half an order of ...
