Hom quartz

hom quartz

Quartz yog cov ntxhia ntau tshaj plaws nyob hauv lub ntiaj teb ua kiav txhab, nws yog tus yam ntxwv ntawm nws ntau hom, duab thiab xim, uas ua rau nws ntxim nyiam heev thiab muaj nqis. Vim tias nws muaj ntau yam thiab ntau yam, nws muaj ntau yam kev siv. Muaj qhov sib txawv hom quartz thiab lawv muaj kev siv sib txawv nyob ntawm qhov xim thiab muaj pes tsawg leeg lawv muaj.

Yog li ntawd, peb yuav mob siab rau kab lus no los qhia rau koj paub tias hom sib txawv ntawm cov quartz uas muaj nyob hauv ntiaj teb thiab dab tsi yog lawv cov yam ntxwv tseem ceeb.

Nws muaj dab tsi?

siv lead ua

Quartz suav nrog ib feem silica gel thiab ob ntu pa. Vim tias lawv muaj pes tsawg leeg, lawv tiv taus ntau heev thiab muaj cov khoom uas ua rau cov ntxhia no ua lub hauv paus zoo tshaj plaws rau cov khoom siv xws li saib lossis xov tooj cua ntau zaus. Cov pob zeb no tseem ntseeg tau tias muaj kev kho kom zoo, tiv thaiv, thiab muaj peev xwm tswj hwm lub zog. Kev coj noj coj ua thaum ub zoo li cov neeg Iyiv, Aztecs thiab Loos siv nws hauv cov hniav nyiaj hniav kub thiab amulets vim lawv ntseeg tias nws muaj lub zog kho lub cev thiab lub siab thiab tiv thaiv lub zog tsis zoo.

Quartz zoo li yuav luag txhua qhov chaw hauv ntiaj teb thiab los hauv cov xim sib txawv. Lawv suav txij ntawm pob tshab mus rau qhov tsis meej, thiab txhua tus tau txiav txim siab kom muaj lub ntsiab lus sib txawv.

Raws li nws muaj pes tsawg leeg, muaj ntau hom quartz, txawm hais tias nto moo tshaj plaws yog amethyst, citrine thiab milky quartz, uas tau txiav txim siab hauv gemology. Dab tsi ntxiv, Muaj qee qhov ntau yam ntawm quartz uas suav hais tias yog lub pov haum txawm tias lawv tus nqi qis. Feem ntau, cov no tau cais raws li lawv cov ntau yam ntawm crystallites, uas yog, lawv cov xim. Qee qhov feem ntau yog:

  • Milky dawb quartz, translucent lossis yuav luag opaque.
  • Cov iav haus luam yeeb, pob tshab thiab cov xim txho.
  • Citrine quartz, daj rau lub teeb txiv kab ntxwv.
  • Amethyst, ntau dua lossis tsawg dua ntshav liab.
  • Rose quartz, vim muaj cov txhuas.

Cov yam ntxwv ntawm hom quartz

hom quartz los ntawm cov xim

Ntawm cov yam ntxwv feem ntau ntawm txhua hom quartz uas muaj nyob peb muaj cov hauv qab no:

  • Quartz iav belongs rau chav kawm ntawm silicates, tshwj xeeb tshaj yog tectosilicates.
  • Nws cov tshuaj lom neeg muaj pes tsawg leeg sib xws rau silicon dioxide (SiO2), uas yog ib feem ntawm silicon thiab ob ntu pa.
  • Nws yog tus yam ntxwv los ntawm nws siab Mohs hardness ntawm 7.
  • Nws qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntaws tshwj xeeb yog zoo ib yam li tus nqi nruab nrab ntawm lub ntiaj teb ua kiav txhab, xws li ntawm 2,6 thiab 2,7 grams ib cubic centimeter.
  • Nws muaj lub ntsiab siv lead ua tseem ceeb sib xws rau cov kab ke siv hexagonal.
  • Nws cov luster zoo ib yam li iav muaju.
  • Nws qhov diaphanous lossis pob tshab yog qhov pom tseeb lossis pob tshab, yog li lub teeb tuaj yeem hla dhau iav.
  • Thaum kawg, nws cov kab txaij tsis muaj xim lossis tsis muaj nyob.

Hom quartz

ntuj muaju

Ntau yam ntawm quartz hais txog txhua hom quartz, qhov sib txawv tsuas yog tias cov khoom tsis huv hauv cov tshuaj lom neeg muaj pes tsawg leeg sib txawv, tab sis thawj cov tshuaj muaj pes tsawg leeg ntawm cov quartz (SiO2) tseem tseem nyob. Qhov sib txawv ntawm cov tshuaj lom neeg muaj pes tsawg leeg muab quartz ntau yam xim.

Dawb crystalline quartz

Crystalline quartz yog txhua hom quartz, lawv zoo li muaj cov txheej txheem muaj kuab zoo thiab pom qhov pom, uas yog, ntawm no koj tuaj yeem pom meej cov duab ntawm quartz thiab txhua yam nws tus yam ntxwv.

Cov piv txwv feem ntau ntawm pab pawg no yog quartz crystals (pob zeb muaju), cov pob zeb hauv av pom hauv granite thiab sandstone, thiab quartz pom hauv cov leeg.

Cryptocrystalline lossis microcrystalline

Pawg no tau tsim los ntawm cov zaub mov quartz, uas yog tsim los ntawm microscopic quartz crystals, uas yog, cov nplais no tsis pom rau qhov muag liab qab, tab sis ua ke lawv tsim ib hom microcrystalline quartz. Pawg no feem ntau hu ua chalcedony.

Keeb kwm thiab tsim cov pob zeb

Quartz yog cov ntxhia ntau tshaj plaws nyob hauv lub ntiaj teb ua kiav txhab, uas yog vim li cas nws thiaj tau siv dav hauv kev faib tawm cov txheej txheem ntawm cov pob zeb uas tsis muaj zog, cov pob zeb ua pob zeb thiab cov pob zeb hloov pauv. Nws keeb kwm, keeb kwm thiab tsim yog nyob ntawm qhov ua tau zoo ntawm thaj chaw geological cuam tshuam nrog nws. Pob zeb-tsim quartz tau pom los sib xyaw nrog ntau cov pob zeb hauv ntau hom pob zeb, ua rau nws ib feem ntawm lawv cov tshuaj lom neeg muaj pes tsawg leeg thiab cov pob zeb zoo nkauj.

Hauv cov pob zeb tawv, quartz crystallizes tob hauv magma thiab tsim ib feem ntawm granite, diorite, granodiorite, thiab lwm yam. Quartz crystallite ntau yam tuaj yeem crystallized los ntawm qhov txias txias ntawm lava thiab cov ntaub ntawv pyroclastic, piv txwv li, quartz yog ib feem ntawm rhyolite, pumice lossis dacite. Thaum kawg hauv las rocas sedimentarias los granos de cuarzo van los ntawm qhov kev cais tawm, meteorización, erosión thauj muaj desde otro tipo de rocas hasta uas yoog raws li nueva roca sedimentaria.

Hydrothermal quartz

Hydrothermal quartz nws yog ib hom crystallized quartz los ntawm silicon dioxide hauv dej hydrothermal, thiab feem ntau cuam tshuam nrog qee yam ntawm cov pob zeb hauv av tso nyiaj los yog cov hlab ntshav hauv dej los yog cov pob zeb hauv av tso rau hauv daim ntawv ntawm cov leeg. Ntau ntawm cov leeg quartz feem ntau nthuav hauv kev tshawb fawb cov ntxhia pob zeb vim tias lawv tuaj yeem muaj cov hlau nthuav xws li kub, nyiaj, thiab zinc.

Hydrothermal quartz yog kev sib xyaw ntawm magma uas muaj dej thiab muaju uas tsim ua lava. Cov txheej txheem no pib los ntawm qhov kub thiab txias siab hauv qab lub ntiaj teb saum npoo av, thiab dej tuaj yeem yaj cov zaub mov sib txawv. Raws li qhov kub ntawm magma txo qis, cov kua uas seem yog quartz thiab dej, cov tshuaj no ntws los ntawm cov kab nrib pleb hauv ib puag ncig pob zeb, qhov twg nws txias thiab pib khov sai.

Cov txheej txheem no tuaj yeem tsim cov pob zeb zoo nkauj quartz, ntxiv rau cov nplais ntawm garnet, calcite, sphalerite, tourmaline, galena, pyrite, thiab txawm tias nyiaj thiab kub. Ib qho piv txwv pom tseeb tshaj plaws ntawm hom no yog amethyst, uas yog xim liab microcrystalline quartz. Cov xim tuaj yeem ntau dua lossis tsawg dua, nyob ntawm seb cov hlau (Fe + 3) nws muaj. Qhov no yog tsim los ntawm cov pob qij txha ntawm kev daws teeb meem hauv cov hlau oxide, ntawm qhov kub qis dua 300 ° C, lawv yuav qhia tus yam ntxwv xim liab.

Kuv vam tias nrog cov ntaub ntawv no koj tuaj yeem kawm paub ntau ntxiv txog hom quartz thiab lawv cov yam ntxwv.
