Feldspars crystallize los ntawm magma raws li ob qho tib si intrusive thiab extrusive igneous pob zeb thiab tseem muaj nyob rau hauv ntau hom metamorphic pob zeb. Pob zeb tsim yuav luag tag nrho ntawm calcic calcic Raws li ib qho alkaline ntiaj teb hlau, calcium yog cov hlau reactive uas tsim cov txheej tsaus nti oxide-nitride thaum raug huab cua. Nws lub cev thiab tshuaj muaj zog zoo ib yam li nws hnyav homologues strontium thiab barium. https://en.wikipedia.org › wiki › Calcium

Yuav ua li cas cov zaub mov muaj nyob hauv feldspar?
Tag nrho cov pob zeb-forming feldspars yog aluminosilicate minerals nrog cov qauv dav dav AT4O8 uas A= potassium, sodium, lossis calcium(Ca); thiab T=silicon (Si) thiab txhuas (Al), nrog rau Si: Al piv ntawm 3: 1 txog 1: 1.
Cov pob zeb metamorphic muaj feldspar?
Feldspars kuj muaj nyob rau hauv cov pob zeb metamorphic (gneiss, amphibolite, schist) thiab hauv cov hlab ntsha hydrothermal.
Puas yog feldspar yog pob zeb tsim pob zeb?
The rock-Kev tsimcov zaub mov yog: feldspars, quartz, amphiboles, micas, olivine, garnet, calcite, pyroxenes. Minerals tshwm sim nyob rau hauv ib lub pob zeb me me yog hu ua "accessory minerals".
