Chondrodite, los ntawm Myanmar

video

Chondrodite yog lub cev muaj roj (mis, mis) Xim (SiO5) 4 (F, OH, O) 2. Txawm hais tias nws yog ib qho tsis tshua muaj ntxhiab, nws yog ib tus neeg tau ntsib ntau tshaj ntawm cov pab pawg neeg ua kom muaj humite. Nws yog tsim nyob rau hauv hydrothermal deposits ntawm lub cev metamorphosed dolomite. Nws kuj pom muaj txuam nrog skarn thiab serpentinite. Nws tshwm sim hauv 2 ntawm Mt. Somma, ib feem ntawm Vesuvius txoj hauv Ltalis, thiab muaj npe ntawm Greek rau "granule", uas yog ib qho cwj pwm rau cov ntxhia no.

Formula

Mg5 (SiO4) 2F2 yog qhov kawg ntawm formula raws li tau muab los ntawm International Mineralogical Association, cov koom haum xNUMX g. Muaj feem ntau OH hauv F sites, txawm li cas los xij, thiab Fe thiab Ti tuaj yeem hloov Mg, yog li cov mis nyuj tov ua tau zoo dua qub (Mg, Fe, Ti) 351.6 (SiO5) 4 (F, OH, O ) 2.

xim

Chondrodite yog daj, txiv kab ntxwv, liab los yog xim av, los yog tsis tshua muaj xim tsis muaj xim, tab sis zoning ntawm cov xim sib txawv yog qhov sib txawv, thiab sib tshuam plates ntawm chondrodite, humite, clinohumite, forsterite thiab monticellite.

kho qhov muag zog

Chondrodite yog siv cov tshuaj khov nab kuab thev naus laus zis (n = 1.592 - 1.643, nβ = 1.602 - 1.655, nγ = 1.619 - 1.675, ib lo lus = 0.025 - 0.037, thiab 2V ntsuas raws 64 ° rau 90 °, xam: 76 ° rau 78 °. Refractive indices yuav nce los ntawm norbergite mus rau clinohumite hauv cov pabcuam humite. Lawv kuj nce nrog Fe2 + thiab Ti4 + thiab nrog (OH) - hloov chaw rau F-. Dispersion: r> v.

ib puag ncig

Chondrodite muaj nyob hauv metamorphic hu rau thaj chaw nruab nrab ntawm carbonate pob zeb thiab acidic los yog alkaline intrusions qhov chaw fluorine tau nkag los ntawm cov txheej txheem metasomatic. Nws yog tsim los ntawm cov dej ntawm olivine, (Mg, Fe2 +) 2SiO4, thiab ruaj khov dua ntau yam kev kub thiab kev ntxhov siab nrog rau cov uas muaj nyob rau hauv ib feem ntawm txoj kab kawg nkaus.
