Qhov sib txawv tseem ceeb ntawm orthoclase thiab plagioclase yog qhov orthoclase tshwm hauv xim ntsuab-daj, thaum plagioclase tshwm rau xim dawb.

Orthoclase thiab plagioclase yog cov zaub mov tseem ceeb. Ob daim ntawv no yog cov tswv cuab ntawm pawg feldspar. Ib lub pob zeb feldspar yog cov pob zeb uas muaj ntau tshaj plaws uas feem ntau tshwm sim raws li cov xim tsis muaj xim lossis xim daj ntseg.

Orthoclase yog dab tsi?

Orthoclase yog ib qho tseem ceeb hauv cov pob zeb feldspar, thiab cov tshuaj formula ntawm cov ntxhia no yog KAlSi₃O_{8 Cov ntxhia yog ib feem ntawm cov pob zeb uas tsis muaj zog, thiab nws yog cov ntxhia tectosilicate ib yam nkaus. Ntxiv mus, qhov no yog hom k-feldspar lossis potassium feldspar. Qhov no tshwm sim raws li cov khoom ntsuab-daj.}

Lub kaw lus siv lead ua ntawm cov pob zeb no yog monoclinic. Mohs scale harness ntawm orthoclase yog 6.0. Nws muaj pearly luster ntawm cleavage nto. Txawm li cas los xij, cov ntxhia streak ntawm orthoclase yog dawb. Ntxiv mus, cov ntxhia no feem ntau yog pob tshab lossis translucent.

Ntxiv mus, cov pob zeb no yog cov khoom siv hauv ntau hom granite. Thaum xav txog kev siv orthoclase, nws yog ib qho tseem ceeb hauv kev tsim cov iav thiab ceramics, piv txwv li. porcelain. Tsis tas li ntawd, nws yog ib qho tseem ceeb nyob rau hauv scouring hmoov. Tsis tas li ntawd, cov pob zeb no yog ib qho tseem ceeb raws li lub gemstone; Piv txwv li, moonstone, uas feem ntau muaj orthoclase, yog ib qho tseem ceeb gemstone.

YPlagioclase yog dab tsi?

Plagioclase yog cov ntxhia tseem ceeb hauv pawg feldspar, thiab cov tshuaj formula ntawm cov ntxhia no yog NaAlSi₃O₈– CaAl ₂Si₂O_{8 Nws kuj yog tectosilicate ntxhia. Crystal system nyob rau hauv cov khoom no yog triclinic. Nws tshwm hauv xim dawb mus rau grey.}

Lub Mohs nplai hardness ntawm cov pob zeb no yuav nyob ntawm 6.0 txog 6.5. Nws muaj vitreous luster thiab cov ntxhia streak yog dawb. Cov khoom yog pob tshab los yog translucent.

Qhov txawv ntawm Orthoclase thiab Plagioclase yog dab tsi?

Orthoclase yog ib qho tseem ceeb hauv cov pob zeb feldspar, thiab cov tshuaj formula ntawm cov ntxhia yog KAlSi₃O₈ Plagioclase yog ib qho Cov ntxhia tseem ceeb hauv pawg feldspar, thiab cov tshuaj formula ntawm cov ntxhia no yog NaAlSi ₃O₈- CaAl _{2 Si}2_O8_{Qhov sib txawv tseem ceeb ntawm orthoclase thiab plagioclase yog tias orthoclase tshwm hauv xim ntsuab-daj, thaum plagioclase tshwm hauv dawb. Ntxiv mus, lub crystal system ntawm orthoclase yog monoclinic thaum nyob rau hauv plagioclase, nws yog triclinic.}

Koj tuaj yeem pom cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm orthoclase thiab plagioclase hauv cov ntawv hauv qab no.

Summary – Orthoclase vs Plagioclase

Hauv cov ntsiab lus, orthoclase yog cov ntxhia tseem ceeb hauv pawg feldspar, thiab cov tshuaj formula ntawm cov ntxhia yog KAlSi ₃ O ₈ while plagioclase yog cov ntxhia tseem ceeb hauv pawg feldspar, thiab cov tshuaj formula ntawm cov ntxhia no yog NaAlSi₃O₈– CaAl ₂Si₂O_{8 Qhov sib txawv tseem ceeb ntawm orthoclase thiab plagioclase yog tias orthoclase tshwm hauv xim ntsuab-daj, whereas Plagioclase tshwm nyob rau hauv cov xim dawb.}
