I-Agate yidwala elihlanganisa ngokuyinhloko i-cryptocrystalline silica, i-chalcedony ngokuyinhloko, ehamba ne-quartz ekristalline. Kubonakala ngokusanhlamvu kwawo okusanhlamvu nokuhlukahluka kombala. Nakuba sithole ama-agate ezinhlotsheni ezahlukene ze-rock host. Sivame ukukuthola ngamadwala ezintaba-mlilo. Futhi kungavamile emadwaleni athile we-metamorphic.

Ama-agate amaningi avela njengamaqhuqhuva emadwaleni entaba-mlilo noma lavas yasendulo. Emigodini engaphambilini eyakhiqizwa yizingqimba kusisindo sokuqala esincibilikisiwe. Kwabe sekugcwaliswa, futhi ngokuphelele noma ngokwengxenye, ngodaba oluyisilinda olufakiwe. Ngezendlalelo ezijwayelekile ezindongeni. I-agate nayo ingagcwalisa imithambo noma imifantu, edwaleni lentaba-mlilo noma eliguquliwe elingaphansi kwezixuku ze-granitic intrusive. Ama-agate anjalo, lapho esikwa ngaphesheya, abonisa ukulandelana kolayini abafanayo. Imvamisa kunesimo esibi ngokweqile. Inikeza ukubonakala okuboshwe kusigaba. Amatshe anjalo yi-agate eboshiwe, nayo i-riband agate ne-agate emthende.

Ekubunjweni kwe-agate ejwayelekile, kungenzeka ukuthi amanzi aqukethe isililika esisombululo esithathwe. Mhlawumbe, kusukela ekuqhekekeni kwamanye ama-silicates ku-lava ngokwawo. Ihlukanisa edwaleni futhi ibeke i-gel silicaous ngaphakathi kwe-vesicles. Izinguquko kumlingisi wesixazululo noma ngaphansi kwezimo zokufaka imali. Kungabangela ukuhluka okuhambelanayo emigqeni elandelanayo. Ngakho lezo zibopho ze-chalcedony zivame ukushintsha ezinye zezingxenye ze-quartz ekristalline.

I-Geode

agathe geodes kukhona Geological izakhiwo yesibili okuyizinto zenzeka amadwala sedimentary kanye mlilo. Ziyakwazi ngokwabo Lokudabuka sedimentary futhi ngokwemvelo eyenziwe kwezulu zamakhemikhali. Geodes azinalutho ngaphakathi, ngalokwanele spheroid ukuba uquqaba oblate yezimbiwa ndaba. Lungase luhlanganise zinhlayiya. Kuyinto ifomu noma nge ukugcwaliswa vesicles e wentaba-mlilo ukuze sub amatshe wentaba-mlilo amaminerali imali. Kusukela uketshezi ezingaphansi kolwandle noma kuqedwa Izigaxana igneous noma concretions syngenetic. Futhi ukugcwaliswa ngokwengxenye yizinto ezifanayo noma futhi namanye amaminerali. It is ukugqashuka kusukela amanzi diagenetic, futhi komhlaba noma uketshezi ezingaphansi kolwandle.

geodes agathe zihluke vugs ngefomu. ifomu Its livela ekuqaleni, babanjwa. Bona izakhiwo ngaphakathi idwala ezizungezile. Geodes futhi zihluke ngamaqhubu. A qhuzwana kuyinto mass ndaba amaminerali oye accreted emhlabeni nucleus qhuzwana. Bobabili izakhiwo base amaminerali aqukethwe ngaphakathi, imali ngaphansi komhlaba noma futhi izinqubo ezingaphansi kolwandle
