Cov feldspars tau muab faib ua 2 pawg dav: plagioclase, uas muaj calcium thiab sodium ; thiab orthoclase, uas muaj poov tshuaj.

Tsis tas li ntawd, feldspar yog dab tsi?

Cov mineralogical muaj pes tsawg leeg ntawm feem ntau feldspars tuaj yeem nthuav tawm raws li cov txheej txheem ternary Orthoclase (KAlSi3O8), Albite (NaAlSi3O8) thiab Anorthite (CaAl2Si2O8). Chemically, cov feldspars yog silicates ntawm aluminium, muaj sodium, potassium, hlau, calcium, los yog barium los yog ua ke ntawm cov ntsiab lus.

Tsis tas li ntawd, orthoclase feldspar yog dab tsi? Orthoclase feldspar yog ib qho potassium aluminium silicate, thiab feem ntau hu ua "potassium feldspar "los yog yooj yim "K-spar," muab tias cov cim tshuaj rau cov poov tshuaj yog "K." Orthoclase muaj nyob rau hauv cov pob zeb tsis muaj zog xws li granite, granite, thiab syenite, nrog rau cov khoom tawg-filling igneous leeg (pegmatite).

Kuj paub yog, qhov twg yog orthoclase feldspar pom?

Nws yog ib qho ntawm feem ntau pob zeb-forming minerals ntawm continental crust. Orthoclase yog feem ntau dav hu ua liab feldspar pom nyob rau hauv ntau granites thiab raws li cov ntxhia tau muab ib tug hardness ntawm "6" nyob rau hauv lub Mohs hardness scale.

Dab tsi yog cov yam ntxwv ntawm feldspar?

Qhov tseeb, feldspar yog tus qauv rau hardness 6 hauv Mohs nplai. Feldspars feem ntau yog dawb los yog ze li ntawm dawb, tab sis lawv yuav pom tseeb los yog lub teeb ntxoov ntawm txiv kab ntxwv los yog buff. Lawv feem ntau muaj ib lub iav luster . Feldspar yog hu ua pob zeb-forming ntxhia, ntau heev, thiab feem ntau ua rau cov pob zeb loj.
