Hmoov Tourmaline yog ib yam khoom uas tau muab zom zoo los ntawm tourmaline, ib yam khoom muaj borosilicate uas paub txog nws cov tshuaj lom neeg sib txawv thiab cov khoom zoo kawg nkaus. Cov mis tshuaj lom neeg dav dav ntawm tourmaline yog NaR3Al6(Si6O18)(BO3)3(OH,F)4, qhov twg R tuaj yeem yog ntau yam hlau ions xws li hlau, magnesium, lithium, lossis manganese, uas muab tourmaline nrog ntau yam xim thiab cov yam ntxwv.

Tsim nyob rau hauv cov xwm txheej geological tshwj xeeb, tourmaline feem ntau yog los ntawm pegmatite dikes thiab qhov kub thiab txias, siab siab metamorphic ib puag ncig. Hauv pegmatites, uas yog cov pob zeb igneous coarse, tourmaline crystals loj hlob los ntawm cov kua hydrothermal nplua nuj nyob rau hauv boron, txhuas, silicon, thiab lwm yam tseem ceeb thaum lub sijhawm lig - theem crystallization ntawm magma. Lub caij no, hauv cov pob zeb metamorphic, tourmaline tsim los ntawm cov tshuaj lom neeg ntawm cov minerals sib txawv nyob rau hauv qhov kub thiab siab, xws li thaum lub sijhawm roob - kev tsim kho.

Cov cheeb tsam loj tsim cov tourmaline thoob ntiaj teb pab txhawb rau kev muab cov hmoov tourmaline. Brazil sawv tawm ua qhov chaw tseem ceeb, khav theeb cov chaw tso nyiaj loj heev vim nws keeb kwm geological dav dav uas muaj cov dej num igneous thiab metamorphic. Sri Lanka kuj ua lub luag haujlwm tseem ceeb, nrog nws cov qauv geological tshwj xeeb uas pab txhawb kev tsim tourmaline. Madagascar, paub txog nws cov nplua nuj minerals, muab ntau cov tourmaline zoo. Hauv Suav teb, Xinjiang thiab Yunnan yog cov chaw tseem ceeb hauv tsev, qhov twg cov chaw geological nyuaj thiab cov tectonic txav mus los ua rau muaj cov xwm txheej zoo rau kev tsim tourmaline ore.

Tom qab khawb av, cov pob zeb tourmaline yuav ua ntau yam txheej txheem los ua hmoov. Thaum xub thawj, nws raug tsoo ua tej daim me me kom tawg cov pob zeb. Tom qab ntawd, los ntawm kev sib tsoo thiab kev sib tsoo, cov pob zeb yuav raug ua kom zoo dua rau hauv cov khoom me me. Cov txheej txheem ntxuav tom qab ntawd raug ua kom tshem tawm cov khoom tsis huv xws li lwm cov zaub mov, av nplaum, thiab cov khoom siv organic, kom ntseeg tau tias cov hmoov tourmaline kawg huv thiab zoo.

Hmoov Tourmaline muaj ntau yam kev siv. Hauv kev lag luam kev noj qab haus huv thiab kev noj qab nyob zoo, nws muaj nqis heev rau nws cov khoom siv hluav taws xob thiab cua sov tshwj xeeb. Thaum kov lub cev tib neeg lossis qee qhov chaw ib puag ncig, hmoov tourmaline tuaj yeem tsim cov hluav taws xob tsis muaj zog thiab cov duab infrared deb. Cov khoom no ntseeg tau tias yuav txhawb kev ncig ntshav, txhim kho kev zom zaub mov, thiab muaj peev xwm txhim kho kev noj qab haus huv tag nrho. Hauv kev lag luam tshuaj pleev ib ce, nws tau ntxiv rau cov khoom siv tu tawv nqaij rau nws cov dej noo, tiv thaiv kev laus, thiab cov teebmeem ntawm daim tawv nqaij. Hauv kev lag luam ib puag ncig, hmoov tourmaline tuaj yeem siv los ntxuav dej thiab huab cua, vim nws tuaj yeem nqus cov tshuaj lom. Tsis tas li ntawd, hauv kev lag luam kev tsim kho thiab kev lag luam ceramics, nws tau koom ua ke rau hauv cov ntaub ntawv los txhim kho lawv cov khoom siv lub cev, xws li lub zog thiab kev ua haujlwm ntev. Zuag qhia tag nrho, hmoov tourmaline qhov kev hloov pauv ua rau nws yog cov khoom siv tseem ceeb hauv ntau yam kev siv niaj hnub no.
