Microcline muaj nyob rau ntawm Bveno, Ltalis ; Kragerø, Nor.; Madagascar; thiab, raws li amazonstone, hauv Urals, Russia, thiab Florissant, Colo., US Rau cov ncauj lus kom ntxaws txog lub cev, saib feldspar (rooj).

Tsuas yog li ntawd, Microcline tsim li cas?

Microcline (KAlSi3O8) yog triclinic qis-kub K-feldspar ruaj khov ntawm qhov kub qis dua 500 ° C. Nws yog feem ntau tsim los ntawm recrystallization los ntawm feldspar, thiab qee zaum los ntawm crystallization ncaj qha los ntawm magma thiab hydrothermal txheej txheem. Microcline feem ntau qhia albite thiab pericline twining.

Tsis tas li ntawd, nrhiav tau anorthite nyob qhov twg? Anorthite yog calcium endmember ntawm plagioclase feldspar mineral series. Cov tshuaj formula ntawm ntshiab anorthite yog CaAl2Si2O8. Anorthite yog pom nyob rau hauv mafic igneous pob zeb. Anorthite tsis tshua muaj nyob rau hauv lub ntiaj teb tab sis muaj ntau nyob rau lub hli.

Kuj Paub, koj yuav txheeb xyuas Microcline li cas?

Microcline tej zaum yuav ntshiab, dawb, daj-daj, cib-liab, los yog ntsuab; Nws yog feem ntau tus cwj pwm los ntawm tus ntoo khaub lig-hatch twinning uas tsim los ntawm kev hloov pauv ntawm monoclinic orthoclase rau hauv triclinic. microcline . Lub npe tshuaj lom neeg yog poov tshuaj txhuas silicate, thiab nws yog hu ua E tooj siv E555.

Qhov txawv ntawm microcline thiab orthoclase yog dab tsi?

Lub xwb qhov sib txawv ntawm lawv yog lawv cov qauv siv lead ua. Microcline crystallizes hauv triclinic system, thiab Orthoclase thiab Sanidine crystallize hauv monoclinic system. Vim nws nyuaj heev rau paub qhov txawv ntawm Orthoclase , Sanidine, thiab Microcline , tej zaum lawv tsuas yog hu ua " Potassium Feldspar ".
