miyala yamtengo wapatali danburite

Danburite ndi mchere wa calcium boron silicate wokhala ndi mankhwala a CaB2(SiO4)2.

Gulani miyala yamtengo wapatali yachilengedwe m'sitolo yathu ya miyala yamtengo wapatali

Danburite mwala

Amatchedwa Danbury, Connecticut, USA, komwe adapezeka koyamba mu 1839 ndi Charles Upham Shepard.

Mwalawu ukhoza kukhala wamitundu yosiyanasiyana kuyambira wopanda utoto mpaka pinki wopepuka komanso wachikasu wonyezimira mpaka bulauni. Koma nthawi zambiri danburite yopanda mtundu nthawi zonse imadulidwa ngati mwala wamtengo wapatali.

Ili ndi kuuma kwa Mohs kwa 7 mpaka 7.5 komanso mphamvu yokoka ya 3.0. Mcherewu umakhalanso ndi mawonekedwe a orthorhombic crystalline. Nthawi zambiri imakhala yopanda mtundu, ngati quartz, koma imathanso kukhala yachikasu kapena yofiirira. Nthawi zambiri amapezeka mumiyala yolumikizana-metamorphic.

Gulu la mineral Dana limatchulidwa kuti sorosilicate, pomwe limalembedwa ngati tectosilicate mu dongosolo la Strunz classification. Mawu onsewa ndi olondola.

Kufanana kwake kwa kristalo ndi mawonekedwe ake ndi ofanana ndi topazi; komabe, topazi ndi yopanda silicate yokhala ndi calcium fluoride. Kuwonekera, kukhazikika komanso kubalalitsidwa kwakukulu kwa danburite kumapangitsa kuti ikhale yamtengo wapatali ngati mwala wazodzikongoletsera.

Danburite Crystal Data

rhombic. Prismatic, makhiristo ooneka ngati diamondi.

Thupi katundu

Kutuluka: Kusawoneka bwino pa f001g.

Kuthyoka: wosagwirizana ndi subconchoidal.

Optical katundu

Zowonekera ku translucent.

Mtundu: Wopanda mtundu, komanso woyera, vinyo wachikasu, wachikasu wofiirira, wobiriwira; wopanda color mu gawo woonda.

Mzere: woyera.

Wala: Kuyambira kusangalatsa mpaka kulimba mtima.

Kulowa

Mu miyala ya granitic ndi metamorphosed carbonate yokhudzana ndi ntchito ya hydrothermal, awiriawiri.

Pakali pano palibe zitsanzo za kukonza kapena kupititsa patsogolo mwala uwu. Palibenso zida zopangira zodziwika kapena zotsatsira pamsika.

Mtundu wa pinki

Mtundu wake nthawi zambiri umachokera ku wopanda mtundu mpaka wachikasu wopepuka, wapinki wopepuka, kapena wofiirira. Ndi kudula kofooka ndi kuuma kwa 7, kumakhala pakati pa miyala yamtengo wapatali yotchuka monga quartz ndi topazi. Ngakhale kubalalitsidwa kwake pang'ono kumatanthauza kuti ma danburites odulidwa alibe moto, miyala yamtengo wapatali yodulidwa bwino imawala kwambiri. Mtundu wotchuka kwambiri ndi pinki

Zotsatira

Mwalawu umapezeka m'miyala yosinthidwa ya carbonate ndi ma granite okhudzana ndi ntchito ya hydrothermal. Zimapezekanso mu evaporites. Minda ya Danbury, Connecticut idatsekedwa kale komanso osafikirika chifukwa cha gulu lalikulu lomwe lakula kwazaka zambiri.

Masiku ano tingapeze magwero ku Japan komanso Madagascar, Mexico ndi Burma. Masiku ano Mexico ndi gwero lofunika kwambiri la miyala yamtengo wapatali.

Mtengo wa danburite ndi mankhwala

Wauzimu kwambiri komanso wofunidwa chifukwa cha mawonekedwe ake, mwalawu ndi mwala wamphamvu wamtima wa chakra womwe umachepetsa ululu wamalingaliro ndikuwonjezera kudzivomereza komanso kuvomereza ena. Krustalo idzakuthandizani "kulola kuwala kwanu kuwalitse". Mphamvu yachikondi yoyera ya kristalo imakubweretserani mtendere ndi bata.
