Ib qho ntawm cov pob zeb uas muaj ntau tshaj plaws yog hornblende. Qhov no yog lub npe nrov rau amphiboles, tsim los ntawm ob lo lus German - "horn" thiab "dazzle". Thaum sib cais, cov muaju ntawm cov pob zeb no zoo li lub horn.

Kev piav qhia sab nraud thiab khoom

Cov tsos ntawm hornblende ua rau nws yooj yim los txheeb xyuas nws ntawm lwm yam minerals. Nws yog qhov txawv los ntawm intergrown luv-columnar crystals nrog hexagonal lossis rhombic hla ntu.

Qhov no yog ib qho nyuaj opaque ntxhia nrog lub ntiajteb txawj nqus tsawg thiab tshwj xeeb cleavage. Lub hardness Performance index yog 5.5-6 nyob rau hauv lub mineralogical nplai. Qhov ceev ntawm hornblende yog qhov nruab nrab ntawm 3100 txog 3300 kg / m³. Cleavage yog cim nyob rau hauv ob txoj kev ntawm lub kaum sab xis ntawm 124 degrees.

Hornblende tsis sib txawv ntawm cov xim. Nws tuaj yeem yog los ntawm lub teeb ntsuab mus rau xim av xim av (feem ntau yog cov pob zeb bas altic nrog cov ntsiab lus siab ntawm alkaline tebchaw). Minerals ntawm tej xim muaj ib tug sib npaug zoo nkauj glassy, semi-metallic luster nrog overflows. Hom no tsis raugcov nyhuv ntawm cov kua qaub. Tej zaum yuav yaj mus rau hauv cov iav ntsuab tsaus yog tias cua sov heev.

Nws yog fickle thiab sib txawv heev. Qhov piv ntawm aluminium rau ferric hlau, nrog rau magnesium rau ferrous, hloov. Tej zaum qhov tseem ceeb ntawm cov poov tshuaj tshaj magnesium.

Nyob rau hauv muaj cov ntsiab lus siab ntawm titanium (txog 3%), cov ntxhia hu ua "bas altic hornblende". Cov muaj pes tsawg leeg yog tsim nyob rau ntawm tag nrho cov ntawm cov tshuaj, cov poov tshuaj oxide tuaj yeem yog los ntawm 10 mus rau 13%, ferrous oxide - los ntawm 9.5 mus rau 11.5%, hlau oxide - 3-9%, magnesium oxide - 11-14%, sodium. oxide - 1.5%, silicon dioxide - 42-48%, aluminium oxide - 6-13%.

Thaum huab cua, pob zeb decomposes rau hauv opals thiab carbonates. Kev sib cuam tshuam nrog hydrothermal kev daws teeb meem ua rau kev hloov pauv ntawm cov ntxhia hauv chlorite, epidote, calcite thiab quartz.

Raws li kev cuam tshuam ntawm ntau yam ntawm lub cev, lub pob zeb tuaj yeem dhau los ua cov txheej txheem tshuaj lom neeg ua rau muaj kev sib xyaw nruab nrab.

Keeb Kwm

Hornblende yog pob zeb tsim cov pob zeb thiab cov khoom tseem ceeb ntawm amphibolites, shales thiab gneisses. Nws tshwm sim, raws li txoj cai, thaum lub sij hawm cuam tshuam ntawm pegmatites ntawm igneous pob zeb. Nws muaj qee zaum pom nyob rau hauv volcanic tshauv raws li ib leeg muaju. Nyob rau hauv daim ntawv ntawm cov khoom tseem ceeb hauv pob zeb uas tau ntws mus rau saum npoo, cov pob zeb no tsis tshua muaj heev.

Hornblende uas tau piav saum toj no tuaj yeem hloov mus ua bas alt. Qhov no feem ntau tshwm sim hauv lava ntws, nyob rau hauv oxidizing tej yam kev mob thiab cua sov mus rau ib tug kub ntawm 800 ⁰С. Cov txheej txheem no yooj yim txaus los tsim cov khoom siv dag zog.

Nyiaj

Loj hornblende crystals tsis tshua muaj thiab yog li ntawd txaus siab rau cov neeg sau khoom. Lawv pom feem ntau hauv gabbro pegmatites, uas tsis muaj ntau heev. Nyob rau hauv lub Urals, nyob rau hauv lub cheeb tsam ntawm Mount Sokolina, zoo-tsim crystals mus txog 0.5 m ntev tau pom. Cov qauv zoo nkauj ntawm cov pob zeb no muaj nyob rau hauv Czech koom pheej, Norway, thiab kuj nyob rau hauv lub roob hluav taws ntawm Vesuvius nyob rau hauv ltalis.

Hornblende yog dav nyob rau hauv German Ore Toj siab, nplua nuj nyob rau hauv txiv qaub-silicate pob zeb. Meissen syenite massif paub txog nws cov nplua nuj deposits ntawm cov pob zeb no. Cov pob zeb loj loj nyob hauv Burma.

Scope of application

Daim ntawv thov tseem ceeb ntawm cov pob zeb no pom hauv kev lag luam. Raws li qee cov txheej txheem thev naus laus zis, hornblende muaj peev xwm hloov mus ua calcite, epidote, quartz, chlorite, thiab tsim cov carbonates thiab opals thaum lub sij hawm decomposition. Nws yog siv los ua cov khoom siv raw rau kev tsim cov iav ntsuab tsaus, nrog rau kev tsim kho ua ib feem ntawm granite.

Fragility thiab tsis pom kev pom tsis pub siv cov ntxhia hauv cov hniav nyiaj hniav kub. Tab sis kev suav nrog hornblende hauv cov khoom siv quartz tso cai rau koj los tsim lub pob zeb zoo nkauj, lub ci ntsa iab thiab cov duab uas tuaj yeem ua tau.qhuas.

Muaj hornblende nyob rau hauv muaj pes tsawg leeg ntawm cov ntxhia hu ua "Apache kua muag", uas yog hom obsidian. Nws ntseeg hais tias lub pob zeb no muaj peev xwm pab tau ib tug neeg tiv nrog ntau yam xwm txheej, nyiam txoj hmoov zoo.

Cov kws tshwj xeeb kawm txog lithotherapy tham txog cov txiaj ntsig zoo ntawm cov ntxhia hauv lub cev tiv thaiv kab mob, digestive thiab excretory. Nws yog txaus los hnav cov hniav nyiaj hniav kub ntawm nws - hlaws, pendants, thiab lwm yam.
