Qhov sib txawv tseem ceeb ntawm pyroxene thiab amphibole yog tias pyroxene yog ib daim ntawv ntawm inosilicate, uas muaj ib leeg chains ntawm SiO3 tetrahedra whereas lub amphibole yog ib daim ntawv ntawm inosilicate, uas. muaj ob txoj saw SiO4 tetrahedra.
Inosilicates yog ib daim ntawv ntawm silicate minerals. Peb hu lawv "chain silicates" thiab. Cov ntxhia no muaj cov hlua sib txuas ntawm silicate tetrahedra nrog SiO3 lossis Si4O11 Muaj ob pawg loj ntawm inosilicates raws li tus naj npawb ntawm chains tam sim no nyob rau hauv cov ntxhia. Lawv yog pyroxene pawg minerals thiab amphibole pab pawg minerals.
YPyroxene yog dab tsi?
Lub sij hawm pyroxene yog hais txog ib qho ntawm cov chav kawm loj ntawm cov pob zeb tsim cov pob zeb silicate, feem ntau muaj calcium, magnesium, thiab hlau thiab feem ntau tshwm sim li prismatic crystals. Nws yog ib qho ntawm ob pawg ntawm inosilicates lossis chain silicates. Tsis zoo li cov pab pawg amphibole, pawg no yog ib qho saw hlau inosilicate. Qhov no yog vim hais tias cov minerals muaj ib tug chains ntawm SiO3 tetrahedra.
Daim duab 01: Diopside ua piv txwv ntawm Pyroxene
Cov zaub mov ntawm pab pawg no tshwm sim hauv cov pob zeb tsis muaj zog thiab metamorphic. Cov tshuaj formula ntawm cov minerals no yog XY(Si, Al)2O6 uas "X" qhia tias calcium, sodium, hlau (+2) los yog magnesium thiab "Y" qhia chromium, txhuas, hlau (+3), cob alt, titanium thiab ntau lwm yam hlau nrog qhov sib piv me me. Raws li cov khoom siv lead ua, muaj ob hom pyroxenes.
- Clinopyroxenes - crystallize hauv monoclinic system.
- Orthopyroxenes - crystallize nyob rau hauv orthorhombic system.
Qee yam piv txwv rau cov zaub mov pyroxene muaj xws li aegirine, augite, clinoenstatite, diopside, jadeite, thiab lwm yam.
Amphibole yog dab tsi?
Lub sij hawm amphibole yog hais txog ib qho ntawm cov chav kawm loj ntawm inosilicate minerals uas muaj hlau los yog magnesium los yog ob qho tib si. Cov zaub mov no tshwm sim raws li prism los yog koob zoo li siv lead ua, muaj ob txoj saw SiO4 tetrahedra; Yog li, peb hu lawv ua ob txoj saw inosilicates. Peb yuav pom cov zaub mov no nyob rau hauv ntau yam xim xws li ntsuab, dub, tsis muaj xim, dawb, daj, xiav, los yog xim av. Yog li ntawd, peb tuaj yeem pom cov zaub mov no ib txwm muaj nyob rau hauv cov pob zeb uas tsis muaj zog lossis metamorphic.
Daim duab 02: Tremolite ua piv txwv ntawm Amphibole
Muaj ob hom qauv siv lead ua peb tuaj yeem pom ntawm cov pob zeb no. Lawv yog cov qauv siv lead ua monoclinic thiab cov qauv siv lead ua orthorhombic. Hauv lawv cov yam ntxwv, lawv zoo ib yam li pyroxenes tab sis txawv ntawm qee yam. Raws li qhov sib txawv ntawm ob pawg no, amphiboles tseem ceeb muaj hydroxyl (OH-) lossis halogen pawg (xws li F thiab Cl). Qee qhov piv txwv ntawm amphibole minerals muaj xws li anthophyllite, holmquistite, ferrogedrite, tremolite, thiab lwm yam.
Qhov txawv ntawm Pyroxene thiab Amphibole yog dab tsi?
Lub sij hawm pyroxene yog hais txog ib qho ntawm cov chav kawm loj ntawm cov pob zeb ua silicate cov zaub mov, feem ntau muaj calcium, magnesium, thiab hlau thiab feem ntau tshwm sim li prismatic crystals. Lawv poob rau hauv qeb ntawm ib leeg saw inosilicates. Qhov no feem ntau yog vim cov minerals muaj ib txoj hlua ntawm SiO3 tetrahedra. Lub sij hawm amphibole yog hais txog ib qho ntawm cov chav kawm loj ntawm inosilicate minerals uas muaj hlau los yog magnesium los yog ob qho tib si. Lawv poob rau hauv qeb ntawm ob chav saw inosilicates vim tias lawv muaj ob txoj saw SiO4 tetrahedra. Ntxiv mus, Pyroxene yuav los yog tsis muaj hydroxyl lossis halogen pawg thaum Amphiboles tseem ceeb muaj hydroxyl (OH-) lossis halogen pawg (xws li F thiab Cl). Cov nram qab no infographic nthuav qhia cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm pyroxene thiab amphibole hauv daim ntawv tabular.
Summary – Pyroxene vs Amphibole
Pyroxene thiab amphiboles yog ob hom silicate minerals uas txawv ntawm ib leeg raws li lawv cov qauv tshuaj. Qhov sib txawv ntawm pyroxene thiab amphibole yog cov pyroxene yog ib daim ntawv ntawm inosilicate uas muaj ib leeg chains ntawm SiO3 tetrahedra whereas lub amphibole yog ib daim ntawv ntawm inosilicate uas muaj ob txoj saw SiO 4 tetrahedra.
