Chondrodite, mai Mianmar

wikiō

ʻO Chondrodite he mineral nesosilicate me keʻano (Mg, Fe) 5 (SiO4) 2 (F, OH,ʻO) 2. ʻOiai he mineral kūponoʻole,ʻo ia ka lālā i hui pinepineʻia e ka hui hui humetene. Hanaʻia ia i loko o nā waihona waiwaiwai mai ka dolomite metamorphosed. Loaʻaʻia kekahi mea pili i ka skarn a me ka serpentinite. Ua loaʻa ma 1817 ma Mt. Somma, kahi hapa o ka Vesuvius ma Italia, a ua kapaʻia mai ka Helene mai no "granule", he mea maʻamau no kēia mineral.

MG5 (SiO4) 2F2 ka hōʻailona hopena o ka lālā i hāʻawiʻia e ka International Mineralogical Association, ka nui o ka 351.6 g. Aia kekahi mau OH i loko o nā pūnaewele F, akā, aʻo Fe a me Ti ua hiki ke pani i ka Mg, no laila ua kākau maikaʻiʻia ke kumukūʻai no ka mineral kūlohelohe (MG, Fe, Ti) 5 (SiO4) 2 (F, OH, O ) 2.

ʻO ka Chondrodite he'ōmaʻomaʻa,ʻalani,ʻulaʻula aʻulaʻula paha, aiʻole iki paha i kaʻiliʻole, akā, ua loiloi ka hoʻolālāʻana i nāʻano likeʻole o ka lahilahi, a ua hōʻikeʻia nā papahana o chondrodite, humite, clinohum, forsterite a me monticellite.

Nā mea leʻaleʻa

ʻO Chondrodite he biaxial (+), me ka heluʻoluʻolu i hōʻikeʻia he like = 1.592 - 1.643, nβ = 1.602 - 1.655, nγ = 1.619 - 1.675, birefringence = 0.025 - 0.037, a me 2V i anaʻia me 64 ° i 90 °, heluʻia: 76 ° i ka 78 °. Hiki i nāʻike kikowaena ke piʻi mai ka norbergite i ka clinohumite ma ka hui humite. Hoʻohui pū lākou me Fe2 + a me Ti4 + a me (OH) - no ka F-. Pāpā: r> v.

'ia

Loaʻaʻia ka Chondrodite ma waena o nā'āpana hulina metamorphic ma waena o nā pōhaku pāʻani a me nā'aeʻaleʻaʻeleʻele a iʻole nā'āpana alkaline kahi i hoʻokomoʻia ai ka momona e nā hana metasomatic. Hanaʻia ia e ka hydration o ka olivine, (Mg, Fe2 +) 2SiO4, a he kūpaʻa ma luna o keʻano o nā mahana a me nā hana e hoʻokomo i nā mea i loko o kahi'āpana o luna.
