Previous work has been unable to establish a relationship between K concentration and D e in single-grains of feldspar. Here we use four well-bleached sediments with low external dose rate (typically ≤1.5 Gy ka −1) to investigate this relationship.Single and multi-grain pIRIR measurements and μ-XRF analyses are made …
Recently, approximately 0.8 billion tons of P-K associated ore containing 5–12 wt.% P 2 O 5 and 5–10 wt.% K 2 O were found in Yichang city, Hubei province, China [5]. Characterization of the ore shows that P- and K-bearing minerals are fluorapatite and potash feldspar, respectively, and the major gangue minerals are dolomite, quartz and …

1.. IntroductionAuthigenic feldspar is ubiquitous in sandstones, but its abundance sharply decreases in carbonate strata. One exception, studied in detail, occurs in the North American Midcontinent, where up to 30% of some Cambrian and Ordovician carbonates are composed of secondary K–feldspar (Hearn and Sutter, 1985, Harper et …
The XRF analysis illustrated in Table 5 shows the concentration of the oxides in feldspar and the composite pigments. The results deduced that feldspar is mainly composed of SiO 2, Al 2 O 3, Fe …
For concentrations below 100 mg/L, spodumene recovery rises from 80.06 % (at 50 mg/L) to 82.16 %, while feldspar recovery significantly decreases from 26.88 % to 11.83 %. Conversely, concentrations exceeding 100 mg/L result in a steady decline in spodumene recovery, accompanied by a slight reduction in feldspar recovery.
China is the second largest producer of feldspar and the largest feldspar consumer in the world (Tanner, 2012).Unfortunately, most of feldspar resources in …
Albite (NaAlSi3O8) is an important industrial mineral especially for ceramic and glass production. Major Fe-containing impurity of albite ore is flaky mica minerals. This study was conducted to determine the applicability of pinched sluicing for pre-concentration of albite ore by exploiting shape effect. Effects of feed solid rate, tilting angle of pinched sluice, …
A high Ba concentration in these veins also suggests a metasomatic origin. Point counted, back-scattered electron photomicrographs, along with microprobe analyses, provide reintegrated K-feldspar and plagioclase compositions for 8 to 12 predetermined random areas per thin section for three samples from Bamble and three samples from the …
The lower Cs concentration in feldspar affirms that the abundance of flux is higher in pegmatites with a higher degree of differentiation, but with similar elevations. ... The spodumene pegmatite exhibits a well-developed perthitic texture of blocky K-feldspar. Distinctive albite veins and film visible in Fig. 6 are attributed to deuteric ...
In comparison to pure PI film, composite films have higher tensile strength and elongation at break due to the addition of 1 wt% KKAc into the PIs. Tensile strength of composite films improves with increasing KKAc concentration, rising from 87.21 MPa for pure PI film to 141.23 MPa for PI/kaolin composite film having 5 wt% KKAc.
The modeled fluid had a low X（CO2） at the peak conditions, while the CO2 concentration in the equilibrium fluids firstly increased during early isothermal exhumation and then decreased at later retrogression. The CO2-depleted feature of the peak fluid indicates a weak metamorphic decarbonation of the impure marbles under UHP …
