Gauin, gauinite kana gauinite - tectosilicate mineral ine sulfate - vhidhiyo
Zviri Mukati:
Gauine, gauinite kana gauinite is sulfate tectosilicate mineral ine Na3Ca (Si3Al3) O12 (SO4) tip pattern.
Tenga matombo echisikigo muchitoro chedu
Inogona kusvika ku5 wt. K2O, pamwe neH2O uye Cl. Iyo feldspar uye inhengo yeboka re sodalite. Iro dombo rakatanga kutsanangurwa muna 1807 zvichibva pazvienzaniso zvakawanikwa muVesuvian lava kuMonte Somma, Italy, uye rakatumidzwa muna 1807 naBrunn-Neergard mushure memuFrench crystallographer René Just Gahuy (1743-1822). Dzimwe nguva rinoshandiswa sechinhu chinokosha.
chitarisiko
Iyo inopenya muisometric system, ichigadzira isingawanzo dodecahedral kana pseudooctahedral makristasi anosvika masendimita matatu mudhayamita; inoitikawo sembeu dzakatenderedzwa. Makristasi akajeka kune translucent, ane vitreous kune oiri luster. Rudzi urwu runowanzo kuve bhuruu, asi rinogonawo kuve chena, grey, yero, girini, uye pink. Muchikamu chakaonda, makristasi haana ruvara kana akacheneruka bhuruu, uye streak yakanyatso chena bhuruu kusvika kuchena.
Properties
Dombo iri isotropic. Yechokwadi isotropic zvicherwa haina birefringence, asi ibwe harina kusimba birefringent pamberi pekuiswa mairi. Iyo refractive index ndeye 1.50. Kunyangwe yakadzikira, segirazi rehwindo rakajairwa, ndiyo yakakosha kukosha kwemaminerari kubva kuboka resodalite. Inogona kuratidza tsvuku-orenji kune mauve fluorescence pasi penguva refu yewavelength ultraviolet mwenje.
Iyo neckline haina kunaka, uye mapatya ari kusangana, kupinda mukati uye polysynthetic. Kutyoka kwacho hakuna kuenderana negoko rakaumbwa, iyo mineral ine brittle uye ine kuoma kwe5 1/2 kusvika 6, inenge yakaoma sefeldspar. Nhengo dzose dzeboka re sodalite dzine zvishoma zvishoma, zvishoma pane zvequartz; Hauyne ndiyo yakaomesesa kupfuura ese, asi ine giravhiti chaiyo ye2.44–2.50 chete.
Kana ibwe rakaiswa pagirazi slide uye rinorapwa ne nitric acid HNO3, ipapo mhinduro inobvumirwa kuti iende zvishoma nezvishoma, monoclinic gypsum sindano inoumbwa. Izvi zvinosiyanisa hauine kubva kune sodalite, iyo pasi pemamiriro akafanana inoumba cubic crystals yeklorite. Iyo mineral haina radioactive.
Muenzaniso kubva kuMogok, Burma
