• Feldspars in Weathering | SpringerLink

    Feldspar weathering occurs via dissolution of all components into solution, with the subsequent precipitation of secondary minerals from solution, and it is the feldspars dissolution rate which controls the overall rate of feldspar weathering. The rate of feldspar dissolution is controlled by the kinetics of surface reactions at the mineralwater interface, not by mass transfer processes ...

    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.

  • Feldspar Distinctions, Characteristics Identifiion

     · Alkali feldspar (also called potassium feldspar or Kfeldspar) has a color range from white to brickred, and it's typically opaque. Many rocks have both feldspars, like granite. Cases like that are helpful for learning to tell the feldspars apart. The differences can be subtle and confusing. That's because the chemical formulas for the feldspars blend smoothly into each other.

    In planepolarized light Kfeldspars may be difficult to tell from plagioclase, though plagioclase has higher refractive indexes. Hint: to highlight Kfeldspar, switch to a medium or low magnifiion objective (usually 4 or 10X works well), mostly close the substage iris, and raise the stage slightly (yes, raise). Though the image will be somewhat out of focus, the low index Kfeldspar grains ...
