Qhov sib txawv tseem ceeb ntawm obsidian thiab tourmaline yog obsidian yog cov khoom siv tsis yog crystalline, whereas tourmaline yog cov khoom siv crystalline.
Obsidian thiab tourmaline yog cov khoom tsis muaj zog. Tourmaline yog cov ntxhia crystalline, tab sis obsidian tsis yog cov ntxhia vim nws tsis yog crystalline thiab nws muaj cov tshuaj lom neeg sib txawv.
Obsidian yog dab tsi?
Obsidian yog cov ntxhia zoo li cov khoom sib xyaw uas tsim los ntawm lava extruded los ntawm lub roob hluav taws uas txias sai sai nrog kev loj hlob siv lead ua tsawg. Nws yog ib hom ntawm ib txwm tshwm sim volcanic iav. Nws tshwm sim raws li ib hom ntawm igneous pob zeb. Cov khoom no tshwm nyob rau hauv tob dub los yog dub xim ntsuab, thiab nws puas yog conchoidal. Nws muaj qhov nyuaj ntawm li 5-6 hauv Mohs nplai ntawm hardness. Obsidian muaj lub vitreous luster thiab yog cov ntxhia pob zeb. Ntxiv mus, nws muaj kev ntxhib los mos uas du thiab iav.
Feem ntau, obsidian tshuaj tsim los ntawm felsic lava, uas yog nplua nuj nyob rau hauv cov ntsiab lus xws li silicon, oxygen, txhuas, sodium, thiab potassium (lub teeb ntsiab). Hom lava no feem ntau tshwm sim hauv cov npoo ntawm rhyolitic lava ntws. Cov no yog hu ua obsidian ntws. Obsidian ntws yog nplua nuj nyob rau hauv silica, uas muab nws viscosity siab. Nws zoo li inhibit qhov diffusion ntawm atoms los ntawm lava (uas tig mus rau inhibit thawj kauj ruam ntawm cov pob zeb siv lead ua).
Feem ntau, obsidian yog ib qho nyuaj, nkig, thiab amorphous ntxhia. Yog li ntawd, nws tawg nrog ntse npoo. Keeb kwm, cov pob zeb no muaj txiaj ntsig zoo hauv kev tsim cov cuab yeej txiav thiab tho, sim ua cov hniav phais, thiab lwm yam. Tam sim no, nws yog qhov tseem ceeb hauv kev tsim cov riam ntse, scalpel hniav, ornamental lub hom phiaj thiab raws li lub gemstone.
Tourmaline yog dab tsi?
Tourmaline yog boron silicate ntxhia muaj tshuaj lom neeg xws li txhuas, hlau, magnesium, sodium, lithium, lossis potassium. Nws yog crystalline ntxhia tshuaj peb tuaj yeem hu ua pob zeb semi-preciuos.
Cov kab ke siv lead ua ntawm tourmaline yog trigonal thiab nws los nyob rau hauv chav kawm ditrigonal pyramidal crystal. Ntxiv mus, cov tshuaj no tshwm sim hauv cov xim dub, tab sis nws tuaj yeem muaj ntau yam xim uas txawv ntawm cov xim tsis muaj xim rau xim av, liab, txiv kab ntxwv, daj, ntsuab, thiab lwm yam. Lub cleavage ntawm cov pob zeb no yog indistinct thiab nws cov pob txha yog tsis sib xws vim nws yog nkig. Lub hardness ntawm cov ntxhia no yog hais txog 7.0 mus rau 7.5 hauv Mohs nplai ntawm hardness. Nws muaj vitreous luster thiab cov ntxhia streak xim yog dawb.
Qhov txawv ntawm Obsidian thiab Tourmaline yog dab tsi?
Obsidian thiab tourmaline yog cov khoom tsis muaj zog. Tourmaline yog cov ntxhia crystalline, tab sis obsidian tsis yog cov ntxhia vim nws tsis yog crystalline thiab nws muaj cov tshuaj lom neeg sib txawv. Obsidian yog cov ntxhia zoo li cov khoom sib xyaw uas tsim los ntawm lava extruded los ntawm lub roob hluav taws uas txias sai sai nrog kev loj hlob siv lead ua tsawg heev thaum tourmaline yog boron silicate ntxhia cov khoom muaj tshuaj xws li txhuas, hlau, magnesium, sodium, lithium, lossis potassium. Qhov sib txawv tseem ceeb ntawm obsidian thiab tourmaline yog obsidian yog cov khoom siv uas tsis yog crystalline thaum tourmaline yog cov khoom siv crystalline.
Cov hauv qab no infographic teev qhov sib txawv ntawm obsidian thiab tourmaline hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Obsidian vs Tourmaline
Obsidian yog cov ntxhia zoo li cov khoom sib xyaw uas tsim los ntawm lava extruded los ntawm lub roob hluav taws uas txias sai sai nrog kev loj hlob siv lead ua tsawg. Tourmaline yog boron silicate ntxhia cov khoom muaj tshuaj xws li txhuas, hlau, magnesium, sodium, lithium, los yog poov tshuaj. Qhov sib txawv tseem ceeb ntawm obsidian thiab tourmaline yog obsidian yog cov khoom siv uas tsis yog crystalline, thaum tourmaline yog cov khoom siv crystalline.
