Moldavite ndi roketi yobiriwira ya silika yopangidwa ndi meteorite impact - kanema

Moldavite ndi mwala wobiriwira, wobiriwira wa azitona kapena wobiriwira wobiriwira wopangidwa ndi meteorite impact kum'mwera kwa Germany pafupifupi zaka 15 miliyoni zapitazo. Uwu ndi mtundu wa tektite.

Kwa nthawi yoyamba, moldavite inaperekedwa kwa anthu asayansi mu 1786. Monga ma chrysolite a Tyn nad Vltavou mu nkhani ya Josef Mayer wochokera ku yunivesite ya Prague, yoperekedwa pamsonkhano wa Czech Scientific Society Mayer 1788. Zippe mu 1836. Moldavskaya Mtsinje ku Czech Republic, kumene zitsanzo zoyamba zomwe zafotokozedwa zidawonekera.

Katundu

Chemical formula SiO2 (+ Al2O3). Maonekedwe ake ndi ofanana ndi amitundu ina ya magalasi, omwe amati kuuma kwa Mohs kuyambira 5.5 mpaka 7. Ikhoza kukhala yomveka bwino kapena yowoneka bwino ndi mtundu wobiriwira wa mossy, wokhala ndi zozungulira ndi thovu zomwe zimatsindika maonekedwe ake a mossy. Mwalawu ukhoza kusiyanitsidwa ndi magalasi obiriwira obiriwira poyang'ana ma leschatellerite ngati nyongolotsi.

ntchito

Miyala yonse yomwe yamwazikana padziko lonse lapansi ikuyembekezeka kufika matani 275.

Pali mitundu itatu ya mwala uwu: wapamwamba kwambiri, womwe nthawi zambiri umatchedwa kuti museum, khalidwe lapakati, komanso nthawi zonse. Madigiri atatu onsewa amatha kusiyanitsa ndi mawonekedwe. Zidutswa zamitundu yosiyanasiyana nthawi zambiri zimakhala zakuda komanso zobiriwira kwambiri, ndipo pamwamba pake zimawonedwa ngati zopindika kwambiri kapena zopindika. Mtundu uwu nthawi zina umawoneka wosweka, kupatulapo mbali zambiri.

Mawonedwe a nyumba yosungiramo zinthu zakale ali ndi mawonekedwe osiyana ndi a fern ndipo amawonekera kwambiri kuposa momwe amawonera. Nthawi zambiri pamakhala kusiyana kwakukulu kwamitengo pakati pawo. Miyala yapamwamba nthawi zambiri imagwiritsidwa ntchito popanga zodzikongoletsera zopangidwa ndi manja.

Ku Cesky Krumlov ku Czech Republic kuli nyumba yosungiramo zinthu zakale ku Moldova, Vltavin Museum. Bungwe la Moldovan linakhazikitsidwa ku Ljubljana, Slovenia mu 2014. Bungweli likuchita nawo kafukufuku, ziwonetsero ndi kukweza miyala padziko lonse lapansi ndipo limaphatikizapo mamembala a geological ochokera kumayiko oposa 30.
