I-Moss agate iyitshe eliyigugu eliyigugu elakhiwa nge-silicon dioxide. Kuyindlela ye-chalcedony efaka amaminerali ombala oluhlaza oshumekwe etsheni, kwakheka imicu namanye amaphethini asikisela ubulembu. Inkambu iyi-quartz ecacile noma emhlophe, futhi amaminerali afakiwe ikakhulukazi ama-oxide we-manganese noma i-iron. Akuyona ifomu le-agate eyiqiniso, ngoba ayinaso isici esichazayo se-agate sokubopha okugxilile. I-moss agate ingeyezinhlobonhlobo ezimhlophe ezinokufakwa okuluhlaza okufana nobulembu. Kwenzeka ezindaweni eziningi. Imibala yakhiwa ngenxa yokulandela umkhondo wensimbi ekhona njengokungcola, okufana ne-chrome noma i-iron. Izinsimbi zingenza imibala ehlukile ngokuya nge-valence yazo, isimo se-oxidation.

Naphezu kwegama layo, i-agate yama-moss ayinayo indaba engokwemvelo futhi ivame ukubunjwa ukusuka emadwaleni aqhutshulwa yi-volcanic.

I-Montana moss agate itholakala kuma-gravelvel alluvial oMfula i-Yellowstone. Izintela zayo phakathi kweSidney neBillings, Montana. Kwaqala ukwenziwa endaweni yaseYellowstone National Park iWyoming ngenxa yomsebenzi wentaba-mlilo. EMontana umbala obomvu uwumphumela we-iron oxide. Futhi umbala omnyama uwumphumela we-manganese oxide.

chalcedony

I-Chalcedony uhlobo lwe-silika lwe-cryptocrystalline. It yakhiwa intergrowths emihle kakhulu ye asebenza ngebhethri futhi moganite. Lawa womabili amaminerali e-silica. Kepha ziyehluka kuleyo quartz enesakhiwo se-trigonal crystal. Ngenkathi i-moganite i-monoclinic. Isakhiwo samakhemikhali esijwayelekile. Kususelwa ekwakhiweni kwamakhemikhali kwe-quartz, yi-SiO2 (i-silicon dioxide).

I-Chalcedony ine-luster waxy. Kungenzeka kube yi-semitransparent noma iguquguquke. Kungathatha imibala ehlukahlukene. Kodwa lezo ezivame ukubonakala zimhlophe zibe zimpunga, ziluhlaza okwesibhakabhaka noma zibe nomthunzi obomvu kusukela obala kuze kube mnyama. Umbala we-chalcedony uthengiswa ngokuhweba uvame ukuthuthukiswa ngokugaya noma ukushisa.
