Leucite, yog ib qho tseem ceeb tshaj plaws ntawm feldspathoid feldspathoid feldspathoid, ib qho ntawm ib pawg ntawm alkali aluminosilicate minerals zoo ib yam li cov feldspars hauv tshuaj muaj pes tsawg leeg tab sis txawm tias muaj qis dua silica-alkali piv. los yog muaj chloride, sulfide, sulfate, los yog carbonate. https://www.britannica.com › science › feldspathoid
feldspathoid | ntxhia | Britannica
minerals, ib qho poov tshuaj aluminosilicate (KAlSi2O6). Nws tshwm sim tsuas yog nyob rau hauv igneous pob zeb, tshwj xeeb tshaj yog potassium-nplua nuj, silica-tsis zoo, lavas tsis ntev los no.
YPuas yog Leucite yog cov ntxhia silicate?
LEUCITE (Potassium Aluminium Silicate)
leucite tsim li cas?
Leucite yog ib tug tswv cuab ntawm pawg feldspathoid, tsim ncaj qha los ntawm cov dej txias hauv cov pob zeb volcanic. Nws tsim nyob rau hauv qis-silica ib puag ncig uas me Quartz tam sim no. Thaum Leucite tsim ntawm qhov kub thiab txias, nws crystallizes li isometric crystals nyob rau hauv trapezohedral crystal daim ntawv.
Koj qhia li cas yog pob zeb lossis pob zeb?
A mineral feem ntau yuav muaj qhov zoo ib yam ntawm sab hauv thiab sab nrauv ntawm tus qauv. Cov yam ntxwv ntawm cov xim thiab kev ntxhib los mos feem ntau tsis txawv txav vim yog homo-geneity. Txawm li cas los xij, xim thiab kev ntxhib los mos feem ntau sib txawv hauv cov pob zeb vim tias pob zeb yog tsim los ntawm ntau yam minerals sib txawv.
Puas pob zeb yog pob zeb?
Nyob ntawm cov ntsiab lus,pob zeb yuav xa mus rau ib lub pob zeb pob zeb, siv lead ua lossis pob zeb. Kev pom ze ntawm granite, pob zeb. Nws yog sib xyaw ntawm cov nplej me me ntawm cov zaub mov quartz (dawb) thiab feldspar (dub). Cov pob zeb hauv av no kuj tseem yuav suav tias yog siv lead ua.
