Thenga i-coral yezinsalela zemvelo esitolo sethu

i-agate coral

I-coral fossil iyitshe lemvelo. Kuvela lapho i-silicate kancane kancane ithatha indawo ye-silicate yasendulo. Ekugcineni iba yi-microcrystalline quartz.

Umbala wamakhorali uvame ukuvela njengamaphethini ezimbali ezincane etsheni. izixhobo zamakhorali zazikhula olwandle olufudumele, olungajulile futhi zidla ama-plankton, njengoba kunjalo nanamuhla. Amakhorali yizilwane zasolwandle ezinomzimba ogobile, umlomo, amathente kanye namathambo.

Lona uhlaka lwamathambo olugcinwe emlandweni wezinsalela. Amakhorali angaba yedwa noma enzeka emakoloni amakhulu. Izinga lokushisa lokuvala kanye nengcindezi yokufaka. Lokhu kwabangela ukuthi la ma-coral deposit aphenduke amatshe ngokuhamba kwesikhathi.

Phakathi kwezinhlobonhlobo zamakhorali amathambo atholakala emhlabeni wonke, ama-specimens anemininingwane eminingi evela ezintabeni zase-Indonesia angeminye yobucwebe be-coral obuyingqayizivele kakhulu.

Amakhorali abelokhu ekhula olwandle cishe iminyaka eyizigidi ezingama-500.

Permineralization of coral izinsalela

I-Permerization inqubo yokugcwalisa izimbotshana ngaphakathi naseduze kohlaka lwamathambo ekhorali oluqinile olusele ngamaminerali afakwe ezixazululweni noma afuduke engqungqutheleni yentlenga. Ekugcineni, ngemva kokufinyela kwemvelo, iba itshe.

Ukushintshwa yinqubo lapho uhlaka lwamathambo lwangempela lwamakhorali luthathelwa indawo, i-molecule nge-molecule, ngamaminerali noma amaminerali asuka kwisisombululo. Isibonelo, i-calcium carbonate evela esakhiweni esiqinile se-coral ithathelwa indawo yi-silica evela kuzixazululo eziboshiwe noma ezifudukayo ngesikhathi sokwakhiwa kwamadwala.

Le nqubo yokulondoloza kabili ingenzeka ngokugxila okuhlukene kwamaminerali engeziwe. Lokhu kulondoloza umehluko phakathi kwezicubu ezithambile zokuqala kanye nezinsalela zohlaka lwamathambo e-coral, njengoba amaminerali ahlukahlukene enikeza amatshe imibala ehlukene.

Izimo ze-geochemical kanye ne-geological lapho lezi zinqubo zenzeka khona ngokuvamile zine-acidic kancane, amazinga okushisa aphansi kanye nezingcindezi eziphansi. Idiphozi ewumphumela yomkhiqizo oshintshwayo i-microscopic noma i-cryptocrystalline quartz, evame ukubizwa ngokuthi i-agate.

E-Indonesia, ukulondolozwa kwamakhanda e-coral kusezingeni eliyingqayizivele. Kubukeka kufana nalokhu kwakwenzeka eminyakeni eyizigidi ezingama-20 edlule. Nakuba ukwakheka kwamakhemikhali manje kuhlukile. I-organic chemistry manje i-silica, kanye nensimbi, i-manganese, namanye amaminerali. Kunama-fern coral, ama-brain coral, ama-cube coral, ama-honeycomb coral nokunye okuningi.

uphondo lwamakhorali

I-Rugosa, ebizwa nangokuthi i-Rugosa noma i-Tetracorallia, iwuhlu olushabalale lwamakhorali awodwa kanye namakholoni ayegcwele olwandle kusukela maphakathi ne-Ordovician kuya ePermian engasekho. Ama-rugons awodwa ngokuvamile abizwa ngokuthi ama-hornbeads ngenxa yekamelo lawo eliyingqayizivele elifana nophondo elinodonga olushwabene noma olungalingani.

Intandokazi

Izintandokazi ziwuhlobo olungasekho lwamakhorali e-tabular ane-polygonal, amakhorali aminyene, okulinikeza igama elivamile, i-honeycomb coral. Izindonga phakathi kwama-corallites zibhobozwa yizimbotshana ezibizwa ngokuthi izimbotshana ezivumela ukudluliselwa kwezakhi phakathi kwama-polyps.

Izintandokazi, njengamakhorali amaningi, zazichuma olwandle olufudumele, olukhanyiswe yilanga, zidla ngokusefa amapulangwe amancane ngamathentekeli awo a-spiny futhi ngokuvamile enza ingxenye yezakhiwo zamadwala. Lolu hlobo lwasakazwa emhlabeni wonke kusukela ku-Late Ordovician kuya ku-Late Permian.

Incazelo kanye nezakhiwo zamakhorali ezinsalela

Ingxenye elandelayo ingeyesayensi mbumbulu futhi isekelwe ezinkolelweni zamasiko.

Ngokusho kwemiqondo ye-metaphysical, i-coral petrified iyitshe legumbi elifanele ukwenza izinguquko. I-agate kukholakala ukuthi isiza ukwelapha ukuphazamiseka kwe-pancreatic futhi ithuthukise ukujikeleza nokujikeleza komoya. Amakhorali ayizinsalela asetshenziselwa ukwelapha izifo zamehlo, isikhumba nesisu. Kukholelwa ukuthi lokhu kwandisa impilo yesevisi.

I-Coral Fossil (noma i-Agatized Coral)

Imibuzo Evame Ukubuzwa

Iminyaka emingaki i-coral eboshiwe?

I-coral endala kunazo zonke ineminyaka eyizigidi ezingu-450 ubudala. Iningi lamatshe atholakala namuhla angaba phakathi kweminyaka eyi-100,000 kanye nezigidi ezingu-25 ubudala, nakuba izibonelo eziningi ezindala ziye zatholakala kusukela enkathini yeSilurian, eminyakeni eyizigidi ezingu-390 edlule.

Ungabona kanjani ukuthi i-coral iyi-fossilized?

Umbala wamakhorali uvame ukuvela etsheni njengezimbali ezincane.

Indlela yokuhlanza i-coral eqoshiwe?

Ngemuva kokuhlanza ngokuphelele, cwilisa i-fossil ku-50% we-apula cider uviniga nesisombululo samanzi. Ngicwilisa i-fossil yami cishe ihora elingu-1 bese ngibuya nesixubho sami ukuze ngisize ukususa okunye okubalulekile kwangaphandle. Lapho uhlanza izinsalela, qiniseka ukuthi izinsalela azizange zifakwe i-asidi.
