Madirus quartzite yog lub pob zeb uas muaj qhov tseem ceeb geological thiab gemological nqi. Nws nyiam cov neeg nyiam nrog nws cov xim tshwj xeeb, qauv thiab kev ntxhib los mos. Lub pob zeb no yog qhov tseem ceeb ntawm geologically vim nws sau cov xwm txheej geological tseem ceeb hauv ntiaj teb keeb kwm, thiab nws kuj tseem nrov hauv thaj chaw gemology.
Madirous quartzite yog tsim nyob rau hauv cov kob ntawm Madagascar, yog li nws tseem hu ua "Madagascar Jade". Nws nyob rau sab qab teb sab hnub tuaj ntawm African sab av loj thiab yog thaj chaw tseem ceeb ntawm geological. Volcanic kev ua si thiab metamorphism nyob rau hauv cheeb tsam ua rau cov xim tshwj xeeb thiab kev ntxhib los mos ntawm Madirus quartzite.
Cov xim ntawm Madirus quartzite yog los ntawm lub teeb daj mus rau txiv kab ntxwv thiab liab, thiab nws cov xim hloov yog nplua nuj thiab muaj yeeb yuj. Nws muaj pes tsawg leeg yog quartz, uas muaj siab transparency thiab luster. Raws li cov qauv, Madirus quartzite muaj cov qauv metamorphic, uas cov metaphenocrysts yog sodium-nplua nuj feldspars, thiab cov matrix yog tsim los ntawm quartz thiab feldspar.
Cov yam ntxwv morphological ntawm Madirus quartzite kuj yog qhov tshwj xeeb heev. Nws qhov hla ntu feem ntau yog tsis sib xws thiab qee zaum nthuav tawm cov qauv sib txawv thiab cov kab nrib pleb. Cov kev ntxhib los mos thiab cov kab nrib pleb ua rau txhua daim ntawm Madirus quartzite tshwj xeeb thiab sib sau ua ke. Tsis tas li ntawd, qee qhov me me tshwm sim hauv qee qhov Madirus quartzite. Cov pob no yog tshwm sim los ntawm cov ntsiab lus hlau, ntxiv cov xim tshwj xeeb rau pob zeb.
Madirus Quartzite kuj ua tau zoo thaum nws los txog rau hardness, ntom thiab durability. Nws hardness yog siab, thib ob tsuas yog pob zeb diamond, ncav cuag 7 degrees ntawm Mohs hardness nplai. Nws qhov ceev kuj tseem loj dua, ncav cuag 2.65 grams / cubic centimeter. Tsis tas li ntawd, vim hais tias nws muaj pes tsawg leeg yog feem ntau quartz, nws muaj lub zog zoo thiab tuaj yeem khaws cia rau lub sijhawm ntev yam tsis muaj kev puas tsuaj yooj yim.
Madirus quartzite yog dav siv hauv kev tsim kho, kho kom zoo nkauj, kev tshawb fawb tshawb fawb thiab lwm yam. Vim nws cov xim tshwj xeeb thiab kev ntxhib los mos, nws feem ntau siv los ua ntau yam khoom dai thiab cov hniav nyiaj hniav kub, xws li necklaces, bracelets, tsej, thiab lwm yam. Tsis tas li ntawd, nws kuj yog siv rau kev kho kom zoo nkauj architectural thiab khoom vaj khoom tsev, coj kev lom zem zoo nkauj rau tib neeg lub neej. nws noble temperament thiab cim ntxim nyiam.
Hais txog kev tshawb fawb tshawb fawb, Madirus quartzite muaj qhov tseem ceeb tshawb fawb tus nqi rau geologists thiab geochemists. Nws tuaj yeem pab cov kws tshawb fawb nkag siab txog cov txheej txheem thiab cov txheej txheem ntawm volcanic kev ua si thiab metamorphism hauv ntiaj teb keeb kwm. Los ntawm kev kawm thiab tshuaj xyuas Madirus quartzite, cov kws tshawb fawb tuaj yeem nkag siab zoo txog kev tsim thiab kev hloov pauv ntawm lub ntiaj teb.
Nyob rau hauv luv luv, Madirus quartzite yog lub pob zeb ntawm qhov tseem ceeb geological thiab gemological nqi. Nws cov xim tshwj xeeb, qauv thiab kev ntxhib los mos ua rau nws yog ib qho ntawm cov neeg nyiam gemstones. Nyob rau tib lub sijhawm, nws kuj tau siv dav hauv kev lag luam xws li kev tsim kho, kho kom zoo nkauj thiab kev tshawb fawb tshawb fawb. Los ntawm kev nkag siab thiab kawm Madirus quartzite, peb tuaj yeem nkag siab zoo dua txog kev tsim thiab kev hloov pauv ntawm lub ntiaj teb, thiab tib lub sijhawm txaus siab rau kev zoo nkauj ntuj muaj nyob hauv pob zeb zoo nkauj no.
