Feldspar minerals make up over 50% of Earth's crust.

Feldspar minerals occur in igneous, metamorphic and sedimentary rocks throughout the world. They are used to make glass, ceramics, paint, plastics, rubber and many other products. Moonstone, labradorite, sunstone and amazonite are examples of feldspar gem materials.

Rubidium

Rubidium

Rubidium is the chemical element with the symbol Rb and atomic number 37. Rubidium is a very soft, silverywhite metal in the alkali metal group. Rubidium metal shares similarities to potassium metal and caesium metal in physical appearance, softness and conductivity. Rubidium cannot be stored under atmospheric oxygen, as a highly exothermic reaction will ensue, sometimes even resulting in the ...

Feldspar

Feldspar

Feldspars are a group of rockforming aluminium tectosilie minerals, containing sodium, calcium, potassium or barium. The most common members of the feldspar group are the plagioclase (sodiumcalcium) feldspars and the alkali (potassiumsodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the Earth's continental crust by weight.

Preparation of highprurity plagioclase separates from a coarsegrained granite (Heemskirk granite, western Tasmania) allows, for the first time, the exact delineation of the amounts of radiogenic Sr, Rb, and common Sr migrating between cogenetic Kfeldspar and plagioclase in a typical postcrystallation granite environment. Further, the isotope reloion is demonstrated to occur in the ...

 · Pulverized samples, containing known amounts of rubidium and cesium, were mixed with borax, microcosmic salt, sodium fluoride, and/or other fluxes and melted in (1) oxidizing or (2) reducing flames. None of the many beads prepared and examined both in hot and cold states had a distinctive color that could be related to the rubidium or cesium content of the samples.
