Слюда. Московский шлиф — — Отличный фильм
Okuqukethwe:
Iqembu lama-micas aqukethe ama-silicates anezingqimba, amaminerali e-phyllosilicate, ahlanganisa izinto ezimbalwa ezihlobene eduze ezine-cleavage ecishe iphelele esisekelweni.
Thenga amatshe ayigugu emvelo esitolo sethu samatshe ayigugu
I-Mica iyikristalu eyi-pseudohexagonal.
Wonke angama-monoclinic, ajwayele amakristalu angama-pseudohexagonal, futhi anokwakheka kwamakhemikhali okufanayo. I-cleavage ecishe iphelele, okuyisici esivelele kakhulu, kungenxa yokuhlelwa kwama-athomu ane-hexagonal, njengepuleti.
Igama livela egameni lesiLatini elithi mica elisho imvuthuluka futhi cishe lithonywa i-micare ukuze likhanye.
Ukuvela kwamashidi e-mica
Kusabalele futhi kwenzeka ezinhlelweni ze-igneous, metamorphic, kanye ne-sedimentary. Amakristalu amakhulu asetshenziselwa izinjongo ezihlukahlukene ngokuvamile akhishwa ku-granitic pegmatites.
Kuze kube ngekhulu lesi-XNUMX, amakristalu amakhulu ayeyivelakancane futhi ebiza ngenxa yokutholakala okulinganiselwe eYurophu. Kodwa-ke, intengo yabo yehla lapho kutholwa izinqolobane ezinkulu futhi zembiwa e-Afrika naseNingizimu Melika ekuqaleni kwekhulu lesi-XNUMX.
I-single-crystal phlogopite eqoshiwe enkulu kunazo zonke yatholwa eMayini ye-Lacey, e-Ontario, eCanada, enobukhulu obungu-10 m × 4.3 m × 4.3 m (33 ft × 14 ft × 14 ft) futhi inesisindo esingamathani angu-330 (320 amathani amade, amathani amafushane angu-360 ). Kuye kwatholakala amakristalu anobukhulu obufanayo eKarelia, eRussia.
Imica yaseMoscow
I-British Geological Survey yabika ukuthi ngo-2005 isifunda sase-Koderma esifundazweni sase-Jharkhand, e-India, sasinemali enkulu kunazo zonke emhlabeni. I-China ibingumkhiqizi omkhulu kunabo bonke, ibalwa cishe ingxenye yesithathu yamasheya omhlaba, ilandelwa yi-US, iSouth Korea neCanada.
Amadiphozithi amakhulu eshidi lensimbi ambiwa eNew England kusukela ngekhulu le-19 kuya kwele-XNUMX. Izimayini ezinkulu bezikhona e-Connecticut, eNew Hampshire naseMaine.
Ukukhiqizwa kwamatshe e-mica
Izinsalela nama-flakes we-mica akhiqizwa emhlabeni wonke. Ngo-2010, abakhiqizi abakhulu kwakuyiRussia (100,000 68,000 53,000 t), Finland (50,000 20,000 15,000 t), South Korea (350,000 t), South Korea (XNUMX t), France (XNUMX XNUMX) kanye ne-XNUMX (XNUMX) . Ukukhiqizwa komhlaba wonke bekungamathani ayi-XNUMX, yize ibingekho imininingwane ethembekile yeChina.
Iningi ishidi likhiqizwa eNdiya (3,500 amathani) naseRussia (1,500 amathani). Ama-flakes avela emithonjeni eminingana: idwala le-metamorphic elibizwa ngokuthi i-schist, eliwumkhiqizo wokucubungula izinsiza ze-feldspar ne-kaolin, i-sediments, kanye nediphozithi ye-pegmatite.
Imithombo ebaluleke kakhulu yeshidi lensimbi yi-pegmatite deposits. Izintengo zamaqabunga ziyahlukahluka ngokwezinga futhi zingasukela ngaphansi kuka-$1/kg ngekhwalithi ephansi iye ngaphezu kuka-$2,000/kg ngekhwalithi ephezulu.
Incazelo ye-mica kanye nezakhiwo zokuphulukisa zezakhiwo ze-metaphysical
Ingxenye elandelayo ingeyesayensi mbumbulu futhi isekelwe ezinkolelweni zamasiko.
UMika unciphisa amandla ezinzwa, uthulisa ingqondo ecabanga ngokweqile, uqinisa kahle izifiso zobuhlakani nezimo zengqondo. Ingasetshenziselwa ukwelapha ukuqwasha nokunciphisa isidingo sokulala ku-mononucleosis. Ingasetshenziswa futhi ukusiza ukukhulula ukuphelelwa amanzi emzimbeni.
Abanye bathi itshe lihlotshaniswa ne-chakra yenhliziyo, kanti abanye bakholelwa ukuthi umbala wetshe uthinta ukuthi iyiphi i-chakra ehlotshaniswa nayo.

Imibuzo Evame Ukubuzwa
Iyini i-mica?
Itshe liwuthuli lwamaminerali olwenzeka ngokwemvelo oluvame ukusetshenziswa kuma-cosmetic substrates, njengokugcwalisa usimende netiyela, nanjengento yokuvikela ezintambo zikagesi. Kutholwe kokuthi: izimonyo, amathayela ophahleni, iphepha lokunamathisela odongeni, okokufaka, usimende netiyela.
I-mica yenzani ngokomoya?
Itshe liyinhlobonhlobo ye-muscovite ene-sheen enhle, ekhanyayo ye-pearly eza ngama-flakes, amapuleti, nezingqimba. Ikhuthaza ukucaca kombono kanye nemfihlakalo. Itshe linciphisa amandla ezinzwa, lithulisa ingqondo ecabanga ngokweqile, liqinise kahle izifiso zomqondo kanye nezimo zengqondo.
Ingabe i-mica iyingozi esikhumbeni?
Njengenye yamaminerali abaluleke kakhulu ezimonyoni, isetshenziswa kabanzi ukwengeza ukukhanya nokukhanya. Ngenxa yokuthi ikhiqizwa ngokwemvelo, iyisithako esidume kakhulu phakathi kwemikhiqizo yobuhle bemvelo nemvelo futhi iphephile ukuthi isetshenziswe cishe kuzo zonke izinhlobo zesikhumba esinemiphumela emibi emincane noma engenazo nhlobo.
