The behaviour of the lattice edges of plagioclases and (Ba,K)-feldspars

Résumé (eng) The lattice edges, a and c, of (Ba,K)-feldspars and plagioclases vary similarly, whereas b varies almost identically, b shows a two-trend variation, whereas a and c show a gradual variation. The behaviour of the lattice edges can be understood, if the effects of M atoms on the (AlSi 3)- and (Al 2 Si 2)- frameworks of the respective end-members are compared with …

Diffusion of Barium in Feldspar

Conclusion • The best possible way to melt the rhyolite is at 850 degrees Celsius for 2 hours with the addition of flux, using a graphite crucible • The barium is greater in the rhyolite crystals than in the glass • During the melting and recrystallization process the Barium will migrate into the feldspar, given more time the

Feldspar: Meaning and Properties

Feldspar vs. Quartz: What''s the Difference? 5 Crucial Signs

With feldspar and quartz, there is plenty of overlap between colors. Since they are both highly abundant crystals, there are plenty of variations. In many cases, though not always, feldspar is cloudy in appearance, while quartz is clear. If you held up a piece of quartz to a light source, the light would shine through.

Feldspar

Feldspars make up an average of 595 g kg−1 of igneous rock, 300 g kg −1 of shale, and 115 g kg −1 of sandstone. Many metamorphic rocks also contain large amounts of feldspars. Therefore, feldspars are present in virtually all sediments and soils in quantities that vary with the nature of parent material of soils and their degree of weathering.

Ba Barium. feldspar and mica through the substitution of K+ by Ba2+, which have similar ionic radii (Ba2+, 135 pm; K+, 138 pm). Barium concentrations tend to be higher in K feldspars than in phyllosilicates. The Ba2+ ion also substitutes for Ca2+ in plagioclase, pyroxenes and amphibole, and in the non silicate minerals apatite and calcite. The

SOLID STATE FORMATION OF BARIUM, STRONTIUM AND …

Eskola (1922) prepared both strontium and barium feldspars in the solid state by heating oxides to 1400o C. with Sr(VO3), and Ba(VO3)2 as fluxes. Eskola''s work indicated that strontium feldspar forms solid solu-tions with anorthite and barium feldspar forms solid solutions with the potash feldspars.
