Igolide le-obsidian eliyigugu
Okuqukethwe:
I-Golden obsidian, eyaziwa nangokuthi i-golden glitter obsidian noma i-gold glitter obsidian, idwala eliqukethe amaphethini amabhamuza egesi asele ekugelezeni kwe-lava, aqondaniswe nezingqimba ezakhiwe ukugeleza kwetshe elincibilikisiwe ngaphambi kokupholisa.
Thenga amatshe emvelo esitolo sethu
Lawa mabhamuza anemiphumela ethokozisayo, abukeka njengokucwebezela kwegolide.
igolide bezinto obsidian
Ingilazi yemvelo yentaba-mlilo yakhiwa ngendlela yedwala elithululwayo elivutha umlilo.
Yakha lapho udaka oluthambile lukhishwa entaba-mlilo luphola ngokushesha ngokukhula okuncane kwekristalu.
Ngokuvamile ingatholakala onqenqemeni lokugeleza kwe-rhyolitic lava okwaziwa ngokuthi ama-obsidian plumes, lapho ikhemistri kanye nokuqukethwe kwe-silica okuphezulu kubangela i-viscosity ephezulu okuthi, uma ipholile ngokushesha, yakhe ingilazi yemvelo ye-lava.
Ukuvinjelwa kokusakazeka kwe-athomu ngalolu daka olunamathela kakhulu kuchaza ukuntuleka kokukhula kwekristalu. Itshe liqinile, liyaphuka futhi li-amorphous, ngakho liqhekeka ngemiphetho ebukhali kakhulu. Esikhathini esidlule, yayisetshenziswa ekwenzeni izinsimbi zokusika nokugwaza, futhi yayisetshenziswa ngokuhlolwa njengama-scalpel blades okuhlinzwa.
I-obsidian yegolide. amaminerali
Akuyona i-mineral yangempela ngoba ayiyona i-crystalline njengengilazi futhi ukwakheka kwayo kuyahlukahluka kakhulu ukuthi kubhekwe njenge-mineral. Ngezinye izikhathi kuthiwa yi-mineraloids.
Yize i-golden obsidian ivamise ukuba mnyama ngombala, njengamatshe ayisisekelo njenge-basalt, i-obsidian inokwakheka kwe-felsic ngokwedlulele. I-Obsidian yakhiwa ikakhulukazi i-SiO2, i-silicon dioxide ivamise ukuba ngu-70% noma ngaphezulu. Amatshe e-crystalline anokwakheka kwe-obsidian amelwe i-granite ne-rhyolite.
Njengoba i-obsidian ikwazi ukumetastable ebusweni bomhlaba, ingilazi igcina iphenduka ibe amakristalu amaminerali acolile; akukho obsidian endala kuneCretaceous etholakele. Lokhu konakala kwe-obsidian kuyashesha lapho kukhona amanzi.
Ukuba nokuqukethwe kwamanzi aphansi, lapho kusanda kwakhiwa, ngokuvamile ngaphansi kuka-1% amanzi ngobuningi, i-obsidian kancane kancane i-hydrates ngaphansi kwethonya lamanzi angaphansi komhlaba, okwenza i-perlite.
