Abstract. Ice-nucleating particles (INPs) enable ice formation, profoundly affecting the microphysical and radiative properties, lifetimes, and precipitation rates of clouds. Mineral dust emitted from arid regions, particularly potassium-containing feldspar (K-feldspar), has been shown to be a very effective INP through immersion freezing in …
Feldspar Distinctions, Characteristics & Identification
Feldspars are hard minerals, all of them with a hardness of 6 on the Mohs scale. This lies between the hardness of a steel knife (5.5) and the hardness of quartz (7). In fact, feldspar is the standard for hardness 6 in the Mohs scale. Feldspars usually are white or nearly white, though they may be clear or light shades of orange or buff.
Igneous phenocrystic origin of K-feldspar megacrysts
Megacrysts of K-feldspar from all four of the granitic plutons containing the largest megacrysts (4–10 cm in length) in the Sierra Nevada composite batholith, and from megacryst-bearing dikes associated with these plutons, all show sawtooth oscillatory zoning marked by varying concentration of BaO. Generally each of about a dozen rather ...

The two types of feldspar are soda feldspar (7 percent or higher Na O) and potash feldspar (8 percent or higher K. 2 2 O).
What is a Primary Crusher?
A primary crusher breaks up large pieces of rock or concrete from the blasting or excavation process and turns them into smaller, more manageable chunks. This is the first step in the crushing process. The smaller pieces can then either be pre-screened or fed directly into a secondary impact or cone crusher.
